As there were many questions regarding range and power - here the answers: Purely solar powered range about 100 miles per day in average holiday conditions / e.g. Med, Carribean ..., about 700 Miles in 7 days without burning any fuel. The "pure solar" speed is about 4 knots, as we have to rechanrge the batteries during daytime while driving, this is only possible at this speed. BUT - it is not the average use of a boat to cross the Atlantic every month. But it is the average use to go out of the marina or bay, go for some swimming, go to the next island and anchor the boat there for the night. So e.g. 50 miles a day are easily feasible at 6 knots, 25 miles at about 7 knots. Purely on solar! Our consumption on the Solarwave 64 is only 12 kW at 6 knots, 19 kW at 7 knots. Any other diesel-powered boat of comparable size and luxury that can do this?And while we are on anchor in a bay, our yachts do not need to run the generator to cook or to run the AirConditioning. BTW - the Solarwave 64 has 2 x 60 kW Motors, topspeed 11 kts, 160 kWh batteries, 15 kWp on the roof with a production of about 80 kWh per day and a generator to refill the batteries in very rare cases with 22 kW. On generator only (not calculating the batteries and the sun) the boat goes 7 knots - 24/7 with a fuel consumption of only 6 liters an hour. The consumption of the household is only 7-10 kWh a day. If you have further questions, please visit our website - Best Regards, Michael, CEO of Solarwave Yachts
This data speaks a lot more and what should be posted in the very beginning. No arguing would appear. Easy to decide speed and range vs clean, quiet and cheap running costs. At this size and cost though battery bank in the 200kWh range would make more sense. I'm planning to start building 30ft light semi-displacement catamaran in summer with 2x15kw and 60kwh battery bank and for this size it's still a close call to make sense going electric. Cruise mostly at 6-7knots with extra power for bad wind/tide times etc. Still a big sacrifice in performance compared to diesels, but i simply hate smell and noise of marine diesels.
Thanks for clearing things up. I have been going on data i got from you guys. I know its all in a starting fase, so i understand, but im sure its all going to be much better in the future. Keep selling!
Thanks "Catamaran channel" for your positive comment and your efforts!!! As we offer 3 models (55, 64 and 75´) and one older one (46´) which we are still mentioning as our "proof of concept" the variety of different values (kW, kWh, A ...) can be mixed up easily - even by our own staff. In addition to that we offer a standard version and optionally more batteries and more powerful motors - which almost every customer orders. So plenty of possibilities for a misunderstanding! ;-) If you or any of your visitors has any question regarding our boats - please feel free to contact me directly via our website www.solarwave-yachts.com - best regards, Michael from Solarwave-Yachts
OH I want the 75 GOOD LORD I want it bad, I do have a suggestion (maybe feasible or not) but what about like 1-3 wind turbines, and like 2 hydro fins? for night operations, understandably a solar boat but while traveling at night the hydro fins should be able to keep the generator on without fuel while it charges the batteries.
I agree. WIND TURBINES on all 4 corners or maybe have them where they can RISE UP and Extend out the blades , when not needed they can Fold down the blades .....just a thought.
Thanks Michael for the summary below. Things can only get better in the future, more speed, longer battery life etc. You are in a great position for the future. Good luck.
Thanks for your kind words, you are absolutely right - things only can get better, and they already get better. For our next boats to be delivered we use batteries of the latest generation. Same brand like Tesla uses, but even higher energy-density = half the size and half the weight to most other lithium batteries on the market - unbelieveable!
Not so sure about the Tesla comparison. I hope this takes off with multiple brands out there and is profitable for most of them. This is a great solution for cat cruisers who just want to take it easy out there, keep the family comfortable, keep the skipper happier with less maintenance and challenges, and allow 2-12 loved ones to visit many sunny and warm places, if not putter around the globe with the solar/generator combo. I'm looking forward to watching this innovation move forward with SolarWave and inevitable competitors to come. Fair winds.
If they can make 1 solar yatch every 9 minutes = then it's the Tesla of the seas... Why has no one tried to mass produce ships ? Stamping them out like model Ts ? They are still being made like cars in the 1920s - slowly by hand. Inefficient .
Love the idea but was disappointed in the interior design and especially the woodwork and cabinetry. I would expect more on such a beautiful boat. Is that customizable?
I been day dreaming about this cat for years now and I wish I could eventually get one. However I would completely reconfigure it for a new life out on the open ocean so I can circumnavigate many times over. Both hulls would be configured for mostly dry storage and maybe a single head. The upper area would get a much smaller Nav area and be mostly configured for living, food preparation, dining and sleeping. Don't need gigantic wasteful sleeping areas. On a cat like that I want to be high up always paying attention to the waters and the horizon even when it comes to my sleeping time. Lol
SolarWave 64 e-catamaran Walkthrough at cannes 2017! 100% solar and emission free. Solarwave 64 has 2 x 60 kW Motors, topspeed 11 kts, 160 kWh batteries, 15 kWp on the roof with a production of about 80 kWh per day and a generator to refill The label says 62 but from now on all 62's are 64's according to the factory. Imagine cruising the seas forever, without looking/paying for diesel or gas.
Catamaran Channel I have been imagining that for about 20 years now. What's crazy is, that has been possible for quite a while now and yet no one has ever really tried to pull it off until now. I could have designed and built this ten years ago myself. Only money stood in my way. Happy to see a manufacturer take solar seriously and build something that actually works and looks good doing it.
Then you got some great imagination, and (maybe) crafting skills. Yes i think this is a fantastic design. (solar powered) As for al the people/experts that doubt the capabilities of this boat. Time will tell and so will buyers or those who get on board during a sea trial.
Solar energy is still really limited. This catamaran probably quite fun for slow cruising at daytime and in protected waters for rich folk. Li-ion batteries got better and cheaper, solar panels also got cheaper and a bit more efficient, especially considering weight/area ratio. That's why we see this boat only now. And even with all those technological advances it's barely enough to move during daytime. I'm all for electric propulsion, but solar alone is far from enough expect for some limited use. Oh, i'm actually planing on building 30ft electric catamaran myself. But i won't be using solar panels, it's just expensive gimmick on a boat. Keep in mind that 1hp is equal to 745watts.
+xellzor entire cities run on solar. it's a matter of how many panels do you have room for. this cat has been extensively tested, so I don't expect it will run out of energy in the middle of a crossing. Thanks for watching!
Which has nothing to do with powering a catamaran, energy requirement is simply too different for available area and weight. Can't even mount panels at an angle for better efficiency as on land. Even cowering all available area on this large cat you get peak 15kW output. Which is 20hp and it's available only during few hours in a sunny day. Cruising in calm waters and short distances, anything else will require large genset and stronger motors. I really like electric propulsion myself, but you need to be aware about limitations, especially in marine environment where it can directly affect your safety.
With battery technology improving this is the way of the future. This size of a boat could easily use a 300kw pack, using a higher battery voltage would make this system more efficient. Love this boat.
Hi, you are absolutely right! We offer different configurations regarding powertrain and battery - also with high voltage system and larger battery capacity - even above 300 kWh. This specific model is an economic and high efficient version - 2 x 60 kW motors, (upgraded to now) 160 kWh battery. Just to give you an example: consumption of 12 kW @ 6 kts, 19 kW @ 7 kts, 30 kW @ 8 kts, 45 kW @ 9 kts and 60 kW @ 10 kts - fully equipped with a total weight on the hook of about 30 tons! ..... is there any other boat of comparable size and comfort on the market that consumes as little as this "Silent Yachts - Solarwave 64"? Please check our 55 and 75 foot Silent Yachts! Best Regards, Michael PS: This specific boat is right now on the way to the Caribbean - crossing the Atlantic ocean. Remember - unlimited range!!!
I am impressed. However, I was a bit disappointed that they chose to make the external cockpit so large, thereby severely limiting the space inside the salon. Then I figured it out. By doing that, they have a smaller AC footprint. Shame, shame...
I can understand that, and your not the only one. This thing is a true "house' on the water. A family of 5 can live on this cat no problem. Its a 64 foot cat with the widest hulls i have ever seen, and ive seen allot. The space you get is all you will ever need. I love it! Thanks for watching!
I absolutely love the concept of Silent Yachts, they are by far the solar power market leaders with very good reason. However the interior space, furnishing and natural light availability just falls flat.. especially as a live-aboard. The size of the cockpit is great for party charters, but impractical as a family living space, it makes the 55 feels more spacious.. I would like to see them rework to bring in some owner operator practicality, comfort and luxury design elements that match the ticket value.
just what everyone needs on their luxury yacht a hatch from a scary dark interior workroom directly into your shower and bedroom cue Psycho music everytime you close your eyes to wash your hair or try and sleep! ;)
its a beautiful concept, just feel like it can be combined with wind power sail boat for a wider application. I know there have already been large yachts that place solar panel on their sheets to reduce emission (really large), anyway, the potential is great. but a boat based only on solar power seems too costly or have too much constraint
Guys dc motors can be wired in two ways one way is to run a dc motor off of the other dc motor and vice versa so if you get both motors running and flip a switch changing the wiring the motors will run at about 45% off their own electricity nonstop for as long as 10,000 hours! If solar were added then maybe 60% without batteries! The batteries would only be needed to get the motors up to about 50% maximum! However I would not recommend going to far without sails!
Lol, you got a point there. Lucky for future buyers that this actually isnt from the tesla factory. Catamarans in general are pretty good in holding up there value.
I also see a lot of complaining about speed. I like electric motor. They are small and light enough for you to change out at sea by yourself. Electrical is easier to fix than oil engine. A lot of people are switching to electric motor for their fish pond in Vietnam because they are more reliable. I rather go with something I can repair or replace by myself than speed. For a lot of people that never travel. You may go to countries that doesn't speak the language or you couldn't exchanged to their currency. It's a lot of headache. Beside they probably won't have the parts or labor to do it.
@@aoristuberon21 It has really matured to the level of decreasing returns. Right now if you are fully charged and motoring at sunset you have enough battery to run 5 knots thru the night. Come daylight you keep running 5 knots and end the day with fully charged batteries...............repeat indefinitely. If your batteries could store double the amount of power, you could start the passage at 7 knots but only be given maybe 6 hours at that speed. The additional charge for those batteries would not be realized until you stop the boat. Battery storage would need to be 10 times current tech to make a discernible difference. And even then you would need to be on anchor for 5 days or even longer to store that much solar power. For east coast to the Caribbean this would work very well. I could see 8 months of cruising using very little fuel or even NO fuel as long as 5 knots works for you. And really, 5 knots in a straight line whenever you want is pretty decent. Quick 20 mile hops could hammer down and have battery power to last thru the night.
So, this would be a SUPERB island hopper, which is the 99% usage time of all yatchs. While island hopping you can run exclusively on solar power, if you do a crossing you then need to use the diesel generator to re-charge. Once that is understood the product can be truly appreciated.
I thought I was the only person looking for alternative to a bomb shelter. I think it's a better alternative. Unlimited fish for food. You are more mobile, instead a bomb shelter. You are like a sitting duck.
Dear Silent Yacht, Thank you for answering most of the questions. Good for you to have the vision. I will be following your progress over the next few months as technology advances rapidly. cheers. Also are you a private company or do you trade publicly?
If ever I had the money to build one of these, I’d design way less tables and seating areas. There’s always way too many places to sit! How many tables does a yacht this size need man!? I’d replace a few areas with more functional purpose based areas. Same for bathrooms.... too many.
I get where your coming from. But that would be a seatrial video, wich would be fine by me. The motors you dont hear, ive heard them running and they are very very quiet. Thanks for watching!
I kind of love the sound of an electric engine :). BTW you could make a video where you talk about the benefits of having a solar powered yacht. Make it similar to online marketing youtube videos. Like: Hello my name is xxx and (what role you have). We are sitting here and enjoying the silence, the waves, the wind and my freshly squeezed Orange juice. Today I wanna talk to you about the top X reasons why you should have a solar powerer yacht. Numer 1: No cost in fuel... (elaborate) Number 2: No smell... (elaborate) Number 3: Can you hear the engine (put the microphone as close to the water near the propeller as possible. Yes it is really silent. (more talking) Number 4: ...... Alright so if you like our trip with the yacht and want to know more the click the link below in the description and it will take you to our sign up page where you can get more information and news before everyone else and we will also show ..... Please subscribe, like and share and please contact us and tell us how much you like solar powered yachts and if you're planning to buy one in the future. Let us know how we can improve our channel and what other videos you would like to see about our yachts. Again my name is .... and see you in the next video. Take care and God bless. So this is my tip. Stay engaged with you audience. Give them value. Also be consistent with your videos because youtube gives you more authority if you do. Cheers :)
I understand why you are saying that. Let me add something i didnt mentioned before. It has a diesel generator on board with 1000 liters of fuel. How smart is that?? Really smart i think. They thought of everything.
the layout is not very good, the fridge is out side. i did not see pocket in the roof for exterior removable wall. if the weather get bad the only dinner is out side. not good for normal operation across many weather type. but the power system is great. it look like a half done design...
Champs Visions 3D Considering the price, I think this is targeted at people that will predominantly be underway in summer or in warmer regions, so it kinda makes sense. But I’m sure it would be relatively easy to spec windows / sliding door and a hatch for the fly-bridge, turning it into a giant living room. Now I just need to win Lotto...
I love the vessel,, I do have 2 major concern tho, 1: open ocean voyage- i would defiantly take this to the south pacific (mostly philippines area) so while there really not seeing a problem, just getting there is what concerns me. 2: Dinghy- Where does the dinghy go? Living anchorage would be a must to have one.
to your questions: 1; getting there is no problem, much smaller boats went there already, all our boats are A-certified (open ocean), for longer periods of bad weather the range extender /diesel-generator supplies you with ample energy. 2; there is a dinghy-garage under the bridgedeck, the middle part of the stern opens. We offer also a hydraulic dinghy-platform in the back. On our Silent 75 you can put a up to 4,40 m long dinghy (Williams Sports-tender 440) into the stb hull + a second dinghy or up to two jetskis on the hydraulic platform. And - you can have another tender-garage in the port hull ---- here the link www.solarwave-yachts.com/english/yachts/silent-75-ready-for-order/
I know this is a catamaran channel, but I think this company should consider at least trying to make a trimarans electric yacht. Trimarans travel faster than catamarans and are much safer: and as for energy ideas, I would have put a type of V.A.W.T turbine as they're much more reliable than a regular turbine. Another thing I would add is a water propulsion drive boat. You dont see very much a trimaran yacht in the water and considering that they are faster, stabler, and safer. I think it would be interesting to see if they would do something with this.
+Raymond Pugh I think the concept is fantastic. the refrigerator is there just for easy access. I don't think they mind the energy it draws when it's standing outside. guess the solar panels make up for it. Thanks for watching!
I understand why you are waiting, it might be allot more affordable then the others. Unfortunately the smallest one out is the 55, wich is going to be available around april/may 2018 with a price-tag starting at €1.270.000. I also think that it depends how much demand there is and how much room for smaller projects there is on there yard. And of course on how successful they are in general. (more capital gives more room for other/different projects) Thanks for watching!
Yeah, shrink this one down just a bit, but keep a lot of the solar panels and batteries. It also doesn't need as many heads, but a nice size master berth and storage space.
Just curious...what happens if you're doing a transatlantic and gets struck by lightning and power is blown? How long is the lifespan for this solar power system before it would need replaced? I know nothing about solar yachts..
+Justin M Like everywhere else, when your struck by lightning, you got a problem :-) if your lucky. The solar panels have the same lifespan as any other solar panel with the same specs. Ofcourse over time they will decrease in efficiency, There's nothing "special" about the panels used here, so there as good as the ones that you can buy for any other boat. Hope that clears it up a little for you. And if you have any more questions just let me know. Thanks for watching!
Is there a way to upgrade the solar panels and add say a Tesla power wall, as tech improves. For example Sunpower makes the highest efficiency panel on the market at about 22% conv efficiency. What are the specs on your panels? Can we swap them for better panels relatively easily?
Alot of not so good looking space consuming furniture in the kitchen and bedrooms... Also I'd prefer 1 large toilet instead of 3 so i can actually not feel claustrophobic when taking a plunge..
great technology demonstrator. even better - a sailboat full of flexible solar panels running electric drives could be useful for motor sailing. avoiding masses of heavy batteries, solar with electric drives would add power at very little extra weight.
she´s good to go already without sails. Why add 1,5 tons of weight, pay 150-200.000 Euro for the rigg, spend a lot of time and money on maintenance - and most of all - produce shade on the panels which would diminish the production significantly and therefore result in a higher fuel consumption? Under "normal and average holiday conditions" the sails would diminish the production of solarpower more than they contribute to the propulsion. Only exemption: really long range cruising in areas with reliable winds like crossing the Atlantic Ocean. But I take any bet, that our Yachts cross the Pacific faster, more comfortable and using less fuel than any other boat of comparable size and comfort. www.silent-yachts.com
11 knots is slow, and I was shocked to read the batteries are drained while it's running with the sun out? How about using some supercapacitors or batteries with supercapacitor technology in series for take-off speed and enabling the use of the sun's energy directly from the panels? Lithium batteries are on their way out. Graphene? Saline or other batteries? A solar generator as well?
Well, it would be nice for Mr. Musk to buy your company and upgrade production to true Mass Production, cranking out a few hundred yachts per day... 35s, 55s, 64s, and 80s Wind / Solar Hybrid Yachts.
The measurement unit for energy, for example as stored in batteries, is kiloWatt-hours. A kiloWatt is a unit of power. Power integrated over time is energy. Power and energy are not the same thing. So presumably you mean 50 kWh battery capacity, which would run the combined 50 kW motors at full power for 1 hour. For the size of the boat, the battery pack and motors are undersized. More powerful motors and a larger battery pack would probably be more practical in terms of reaching destinations in a reasonable amount of time. That said, even the smaller motors probably move the boat much more efficiently under electric propulsion than people expect. Electric drive is highly efficient. Also, while this all seems somewhat esoteric and unusual now, due to falling battery costs, most new (sail)boats and many retrofitted ones will have electric motors and battery packs within a decade or two. As battery costs continue to fall, it becomes cheaper to install electric drive than internal combustion. Electric is about 3x more energy efficient than fossil fuels and vastly simpler, quieter, smoother, more reliable, etc. No cooling systems, no oil changes, no balky transmissions, almost zero maintenance, instant response at all times, etc. For long distance sailing a fossil fuel electric generator can be added, but for most sailing, solar panels, wind generators, shore power, and hydro generation (regeneration) can charge the battery pack; multiple of those can work while sailing. Electric drive has strong synergies with sailing, particularly due to hydro generation, which recharges the battery pack due to the motion of the boat through the water while under sail.
Probably it's not efficiency of electric motors, but what most people don't realize is how little power you need to move a large boat at slow speed. At least when not going against tide or wind or both at same time. Although electric certainly isn't 3x more efficient than ICE, it's always has high efficiency from lowest to highest rpm. For example if boat runs at different speeds often, electric propulsion and genset might save quite a bit of fuel, if run mostly at same speed there will be barely any difference or even burn more fuel than traditional combustion engine setup. I will be making electric 30ft catamaran in near future, but i'm doing it only because my planed use and location allows it. 2x15kw and 50-60kW pack, which will allow for modest cruising speeds and some extra power for short periods of time when necessary. And my selected hull is rather light and efficient, most power cats won't go far with this little power. Sadly until energy storage gets way better than currently available, electric propulsion won't go mainstream. Another problem is dealing with high current, while in my case it's still not that big and relatively safe, for larger boats it becomes another problem to deal with.
Thermodynamic energy efficiency of electric vehicles is about 3x that of fossil fuel vehicles. EVs become equivalent in efficiency if fossil fuels are used as a range extender to generate power for electric propulsion over much longer distances than the battery pack can hold. It's actually pretty similar for cars. A BMW 3 series has about 4x more (fossil fuel) energy used per mile than a Tesla Model 3, etc. Same for Hydrogen fuel cells, etc. Plug in hybrids become less efficient as the fossil engine is used for longer distance travel. Propulsion energy goes up exponentially with speed for a displacement hull, so yes, slower speeds are more efficient. No one would really run a (reasonably sized) electric motor at full power for a long time if they wanted efficiency. Slower is better, within some ranges of practical speeds.
3x if compare worst engine to best electric and not taking into account any losses for electricity storage and transfer, i.e. not related to actual use. Controllers, charging/discharging batteries, resistance etc all take a big chunk of total efficiency that you didn't include. If fuel doesn't leak anywhere and it shouldn't, engine will burn same amount of fuel you got from your source. But input electricity and what can be used by motor is considerably higher. And i think can forget about hydrogen fuel cells for a while, round trip for hydrogen is way too inefficient, energy density is really high if can solve storage problems, but that's it. I'm not even touching source of electricity. Which is yet another topic and is highly depended on location.
3x does take into account all losses including charging and discharging the battery pack, but mostly from automobiles that use highly efficient AC induction or permanent magnet motors and high voltage Lithium ion battery packs. DC motors, low voltage systems, etc. are less efficient, but higher efficiency electric propulsion systems for boats are starting to become more available, and the efficiency of boat electric drives will only improve as automotive EV technology migrates over. The costs will also fall as they have for electric automobiles. Electric drive on the boat is arguably the most flexible of all. It can use as input energy: fossil fuels via an internal combustion generator, wind generators, shore power, solar panels, hydro generators (regeneration by water flow over the props during sailing), alternator on conventional motor, (currently highly impractical) fuel cells, etc. Several of those are very low Carbon footprint.
How you are getting 3x? A good engine transfers 30-45% as power, the rest going into heat. Fuel from the place it's produced to the point it's used in engine doesn't reduce by any significant amount. First can start with batteries, li-ion has about 80-90% round trip efficiency at best, do any relatively fast charging and this efficiency drops dramatically the faster you charge. Controller then reduces this by another 10% on average. Then PMAC motors are 90-94% and that's one of best ones, brushed motors are in the range of 80-84%. Throw in any necessary current conversions from sources and wiring loss... you still think it's 3x more efficient?
Yes i forgot to film them. In the next video, there latest build, the silent yacht 55. I did film everything, including motors and batteries. Stay tuned! Thanks for watching!
I saw some of these are more affordable than their diesel counterparts and you're not spending as much money on maintenance I just wish I had the money for these maybe my life wouldn't be as miserable
Government killed off the original Tesla creator, he had created a motor that can run forever, only using earths energy. But oil and gas companies didn't like that.
I thank you for the vid, however you did not let us get a good look at the motor. Trying to sell someone on electric motor and not be able to see it is a downer.....i feel like i wasted some time watching this.
nice concept, but still not good enough. Not designed for regular circumnavigation, so it is just another weekend boat. makes me sad, would have loved to see it as a world cruiser, but I guess technology isnt there yet
Clicks on video hoping for an in depth review of the boat. One second in and the trademark irritating you tube channel music starts up. 🙄Immediately heads back over to Aquaholics channel.
Of course she has watertight sections - there are another 5 meters in front of the master cabin and about 4 meters behind - absolutely weatertight sections. BTW - ask and better check other cats for that, you would be surprised!
Why not add small propellers under the boat that generate additional electricity when you are driving the boat, simple way to increase zero emission range

As there were many questions regarding range and power - here the answers: Purely solar powered range about 100 miles per day in average holiday conditions / e.g. Med, Carribean ..., about 700 Miles in 7 days without burning any fuel. The "pure solar" speed is about 4 knots, as we have to rechanrge the batteries during daytime while driving, this is only possible at this speed. BUT - it is not the average use of a boat to cross the Atlantic every month. But it is the average use to go out of the marina or bay, go for some swimming, go to the next island and anchor the boat there for the night. So e.g. 50 miles a day are easily feasible at 6 knots, 25 miles at about 7 knots. Purely on solar! Our consumption on the Solarwave 64 is only 12 kW at 6 knots, 19 kW at 7 knots. Any other diesel-powered boat of comparable size and luxury that can do this?And while we are on anchor in a bay, our yachts do not need to run the generator to cook or to run the AirConditioning. BTW - the Solarwave 64 has 2 x 60 kW Motors, topspeed 11 kts, 160 kWh batteries, 15 kWp on the roof with a production of about 80 kWh per day and a generator to refill the batteries in very rare cases with 22 kW. On generator only (not calculating the batteries and the sun) the boat goes 7 knots - 24/7 with a fuel consumption of only 6 liters an hour. The consumption of the household is only 7-10 kWh a day.

I agree. WIND TURBINES on all 4 corners or maybe have them where they can RISE UP and Extend out the blades , when not needed they can Fold down the blades .....just a thought.
The layout is not very effecient but it looks really nice. I wish the main area wasn't so tight but out of 10 it's a really nice 8.5.
Thanks Michael for the summary below. Things can only get better in the future, more speed, longer battery life etc. You are in a great position for the future. Good luck.
Thanks for your kind words, you are absolutely right - things only can get better, and they already get better. For our next boats to be delivered we use batteries of the latest generation. Same brand like Tesla uses, but even higher energy-density = half the size and half the weight to most other lithium batteries on the market - unbelieveable!
This yacht is on my bucket list. I will own the beautiful boat.
I really liked that big crawl space in storage area off the shower.
Wish there was a person standing in the shots to give a sense of scale. Great video!
Not so sure about the Tesla comparison. I hope this takes off with multiple brands out there and is profitable for most of them. This is a great solution for cat cruisers who just want to take it easy out there, keep the family comfortable, keep the skipper happier with less maintenance and challenges, and allow 2-12 loved ones to visit many sunny and warm places, if not putter around the globe with the solar/generator combo. I'm looking forward to watching this innovation move forward with SolarWave and inevitable competitors to come. Fair winds.
what you described is what about 98% of the sailors are looking out for.
If they can make 1 solar yatch every 9 minutes = then it's the Tesla of the seas... Why has no one tried to mass produce ships ?
Stamping them out like model Ts ? They are still being made like cars in the 1920s - slowly by hand. Inefficient .
I'm just here to become better informed about boating. It's amazing how people can make an argument about ANYTHING!! 😂😂😂😂😂.
Love the idea but was disappointed in the interior design and especially the woodwork and cabinetry. I would expect more on such a beautiful boat. Is that customizable?
Yes whatever you want on this one, fully custom.
Thanks for watching!
I been day dreaming about this cat for years now and I wish I could eventually get one. However I would completely reconfigure it for a new life out on the open ocean so I can circumnavigate many times over. Both hulls would be configured for mostly dry storage and maybe a single head. The upper area would get a much smaller Nav area and be mostly configured for living, food preparation, dining and sleeping. Don't need gigantic wasteful sleeping areas. On a cat like that I want to be high up always paying attention to the waters and the horizon even when it comes to my sleeping time. Lol
like a 2017 Neel 45?
rgray318 oh my gosh, you and I are thinking the same thing (bug out boat)
A single head is begging for that head to break in the middle of an ocean someplace...
SolarWave 64 e-catamaran Walkthrough at cannes 2017!
100% solar and emission free.
Solarwave 64 has 2 x 60 kW Motors, topspeed 11 kts, 160 kWh batteries, 15 kWp on the roof with a production of about 80 kWh per day and a generator to refill
The label says 62 but from now on all 62's are 64's according to the factory.
Imagine cruising the seas forever, without looking/paying for diesel or gas.
Catamaran Channel I have been imagining that for about 20 years now. What's crazy is, that has been possible for quite a while now and yet no one has ever really tried to pull it off until now. I could have designed and built this ten years ago myself. Only money stood in my way. Happy to see a manufacturer take solar seriously and build something that actually works and looks good doing it.
Then you got some great imagination, and (maybe) crafting skills.
Yes i think this is a fantastic design. (solar powered)
As for al the people/experts that doubt the capabilities of this boat.
Time will tell and so will buyers or those who get on board during a sea trial.
Solar energy is still really limited. This catamaran probably quite fun for slow cruising at daytime and in protected waters for rich folk. Li-ion batteries got better and cheaper, solar panels also got cheaper and a bit more efficient, especially considering weight/area ratio. That's why we see this boat only now. And even with all those technological advances it's barely enough to move during daytime. I'm all for electric propulsion, but solar alone is far from enough expect for some limited use. Oh, i'm actually planing on building 30ft electric catamaran myself. But i won't be using solar panels, it's just expensive gimmick on a boat. Keep in mind that 1hp is equal to 745watts.
+xellzor entire cities run on solar. it's a matter of how many panels do you have room for. this cat has been extensively tested, so I don't expect it will run out of energy in the middle of a crossing.
Thanks for watching!
Which has nothing to do with powering a catamaran, energy requirement is simply too different for available area and weight. Can't even mount panels at an angle for better efficiency as on land. Even cowering all available area on this large cat you get peak 15kW output. Which is 20hp and it's available only during few hours in a sunny day. Cruising in calm waters and short distances, anything else will require large genset and stronger motors. I really like electric propulsion myself, but you need to be aware about limitations, especially in marine environment where it can directly affect your safety.
Thanks for the authentic and positve video - Michael Köhler, from Solarwave-Yachts
Thanks for the compliment.
And of course, Thanks for watching!
With battery technology improving this is the way of the future. This size of a boat could easily use a 300kw pack, using a higher battery voltage would make this system more efficient. Love this boat.
Hi, you are absolutely right! We offer different configurations regarding powertrain and battery - also with high voltage system and larger battery capacity - even above 300 kWh. This specific model is an economic and high efficient version - 2 x 60 kW motors, (upgraded to now) 160 kWh battery. Just to give you an example: consumption of 12 kW @ 6 kts, 19 kW @ 7 kts, 30 kW @ 8 kts, 45 kW @ 9 kts and 60 kW @ 10 kts - fully equipped with a total weight on the hook of about 30 tons! ..... is there any other boat of comparable size and comfort on the market that consumes as little as this "Silent Yachts - Solarwave 64"? Please check our 55 and 75 foot Silent Yachts! Best Regards, Michael
PS: This specific boat is right now on the way to the Caribbean - crossing the Atlantic ocean. Remember - unlimited range!!!
At a 100 miles a day crossing the Atlantic you better have a hell of a lot of fridge space lol.
@@jimbotheassclown The average 40 foot or so sailboat travels 100 miles per day on trans ocean trips. The occupants don't starve.
I am impressed. However, I was a bit disappointed that they chose to make the external cockpit so large, thereby severely limiting the space inside the salon. Then I figured it out. By doing that, they have a smaller AC footprint. Shame, shame...
This is exactly what I want to get when I retire.
I can understand that, and your not the only one.
This thing is a true "house' on the water. A family of 5 can live on this cat no problem.
Its a 64 foot cat with the widest hulls i have ever seen, and ive seen allot. The space you get is all you will ever need.
I love it!
Thanks for watching!
I am retired at 44 and looking up custom options for this boat, look out world.
Thats great news, congratz.
Thanks for watching!
Can i join the journey :))
It's nice, but can they manufacture 1,000 of them each day ? You can't call it the Tesla of the seas unless they can reallly mass produce.
Wow! Great video. Who ever designed the layout, did a great job! It’s like they thought of everything
My dream, congratulation for this really nice Boat! Kind regards from Germany
Thanks for watching!
I absolutely love the concept of Silent Yachts, they are by far the solar power market leaders with very good reason. However the interior space, furnishing and natural light availability just falls flat.. especially as a live-aboard. The size of the cockpit is great for party charters, but impractical as a family living space, it makes the 55 feels more spacious.. I would like to see them rework to bring in some owner operator practicality, comfort and luxury design elements that match the ticket value.
just what everyone needs on their luxury yacht a hatch from a scary dark interior workroom directly into your shower and bedroom cue Psycho music everytime you close your eyes to wash your hair or try and sleep! ;)
its a beautiful concept, just feel like it can be combined with wind power sail boat for a wider application. I know there have already been large yachts that place solar panel on their sheets to reduce emission (really large), anyway, the potential is great. but a boat based only on solar power seems too costly or have too much constraint
A sheet on a boat is a rope.
Guys dc motors can be wired in two ways one way is to run a dc motor off of the other dc motor and vice versa so if you get both motors running and flip a switch changing the wiring the motors will run at about 45% off their own electricity nonstop for as long as 10,000 hours! If solar were added then maybe 60% without batteries! The batteries would only be needed to get the motors up to about 50% maximum! However I would not recommend going to far without sails!
I would invent a roll out solar array that can be deployed from both sides with floats
It would increase your current array by 300%
ideally I want to do this on a sail boat. Being able to use air conditioning and not running a generator is a big thing.
Pro level footage and cool music! These boats are amazing, yes the Tesla of the ocean!
So worthless after 3 years? Lol hopefully they get better parts support than tesla...🙄
Lol, you got a point there.
Lucky for future buyers that this actually isnt from the tesla factory.
Catamarans in general are pretty good in holding up there value.
Lololol @0:25 "that salon is bigger than my entire boat!" 🤣
I also see a lot of complaining about speed. I like electric motor. They are small and light enough for you to change out at sea by yourself. Electrical is easier to fix than oil engine. A lot of people are switching to electric motor for their fish pond in Vietnam because they are more reliable. I rather go with something I can repair or replace by myself than speed. For a lot of people that never travel. You may go to countries that doesn't speak the language or you couldn't exchanged to their currency. It's a lot of headache. Beside they probably won't have the parts or labor to do it.
I may want to wait for improved solar and battery to catch up to this idea for transocean travel.
They’ve improved it with the 80. I think solar electric sailing around the equator on the Silent Electric 80 would be the best of all worlds.
@@aoristuberon21 It has really matured to the level of decreasing returns. Right now if you are fully charged and motoring at sunset you have enough battery to run 5 knots thru the night. Come daylight you keep running 5 knots and end the day with fully charged batteries...............repeat indefinitely. If your batteries could store double the amount of power, you could start the passage at 7 knots but only be given maybe 6 hours at that speed. The additional charge for those batteries would not be realized until you stop the boat. Battery storage would need to be 10 times current tech to make a discernible difference. And even then you would need to be on anchor for 5 days or even longer to store that much solar power. For east coast to the Caribbean this would work very well. I could see 8 months of cruising using very little fuel or even NO fuel as long as 5 knots works for you. And really, 5 knots in a straight line whenever you want is pretty decent. Quick 20 mile hops could hammer down and have battery power to last thru the night.
Perfect yacht for Cabo San Lucas, Mexico. Please Lotto god, do me a favor for once!
So, this would be a SUPERB island hopper, which is the 99% usage time of all yatchs. While island hopping you can run exclusively on solar power, if you do a crossing you then need to use the diesel generator to re-charge. Once that is understood the product can be truly appreciated.
I love this boat and wish that I can afford it ( perfect bug out boat)!
If my checkbook could support it I'd be heading there tomorrow to get them started customizing mine.
I thought I was the only person looking for alternative to a bomb shelter. I think it's a better alternative. Unlimited fish for food. You are more mobile, instead a bomb shelter. You are like a sitting duck.
Dear Silent Yacht, Thank you for answering most of the questions. Good for you to have the vision. I will be following your progress over the next few months as technology advances rapidly. cheers. Also are you a private company or do you trade publicly?
What is the yearly maintenance on this boat?
If ever I had the money to build one of these, I’d design way less tables and seating areas. There’s always way too many places to sit! How many tables does a yacht this size need man!? I’d replace a few areas with more functional purpose based areas.
Same for bathrooms.... too many.
Its custom.
Çok güzel. Güneş enerjisi insanlığın kurtuluşu olacak. Umarım hızla yaygınlaşır.
Izlediğiniz için teşekkürler!
Do you have any videos where we can hear the electric motor, winds and the waves with no music?
I get where your coming from.
But that would be a seatrial video, wich would be fine by me.
The motors you dont hear, ive heard them running and they are very very quiet.
Thanks for watching!
I kind of love the sound of an electric engine :).
BTW you could make a video where you talk about the benefits of having a solar powered yacht. Make it similar to online marketing youtube videos. Like:
Hello my name is xxx and (what role you have). We are sitting here and enjoying the silence, the waves, the wind and my freshly squeezed Orange juice. Today I wanna talk to you about the top X reasons why you should have a solar powerer yacht.
Numer 1: No cost in fuel... (elaborate)
Number 2: No smell... (elaborate)
Number 3: Can you hear the engine (put the microphone as close to the water near the propeller as possible. Yes it is really silent. (more talking)
Number 4: ......
Alright so if you like our trip with the yacht and want to know more the click the link below in the description and it will take you to our sign up page where you can get more information and news before everyone else and we will also show ..... Please subscribe, like and share and please contact us and tell us how much you like solar powered yachts and if you're planning to buy one in the future. Let us know how we can improve our channel and what other videos you would like to see about our yachts.
Again my name is .... and see you in the next video. Take care and God bless.
So this is my tip. Stay engaged with you audience. Give them value. Also be consistent with your videos because youtube gives you more authority if you do.
Cheers :)
62ft? Also, is it possible to do some vertical farming inside?
Maybe someone could invent a wind powered boat.
+Benjamin Nordland Problem with that is, when the wind is gone your stuck.
Thanks for watching!
Wind powered boats .... hmmm sounds familiar...
Catamaran Channel when the sun is gone ... this one will be stuck also. Good luck with storing enough energy....
I understand why you are saying that.
Let me add something i didnt mentioned before.
It has a diesel generator on board with 1000 liters of fuel.
How smart is that?? Really smart i think. They thought of everything.
If it has a diesel generator with a 1000 liters of fuel that makes the zero emissions line false.
the layout is not very good, the fridge is out side. i did not see pocket in the roof for exterior removable wall. if the weather get bad the only dinner is out side. not good for normal operation across many weather type. but the power system is great. it look like a half done design...
Champs Visions 3D Considering the price, I think this is targeted at people that will predominantly be underway in summer or in warmer regions, so it kinda makes sense. But I’m sure it would be relatively easy to spec windows / sliding door and a hatch for the fly-bridge, turning it into a giant living room. Now I just need to win Lotto...
I love the vessel,, I do have 2 major concern tho,
1: open ocean voyage- i would defiantly take this to the south pacific (mostly philippines area) so while there really not seeing a problem, just getting there is what concerns me.
2: Dinghy- Where does the dinghy go? Living anchorage would be a must to have one.
to your questions:
1; getting there is no problem, much smaller boats went there already, all our boats are A-certified (open ocean), for longer periods of bad weather the range extender /diesel-generator supplies you with ample energy.
2; there is a dinghy-garage under the bridgedeck, the middle part of the stern opens. We offer also a hydraulic dinghy-platform in the back. On our Silent 75 you can put a up to 4,40 m long dinghy (Williams Sports-tender 440) into the stb hull + a second dinghy or up to two jetskis on the hydraulic platform. And - you can have another tender-garage in the port hull ---- here the link www.solarwave-yachts.com/english/yachts/silent-75-ready-for-order/
Beautiful............................
The video says silent 64 but the transfers stuck on this boat says silent 62 !? Which one is it ?
Bob Fox, dont place links to other sites please.
How much is this
I know this is a catamaran channel, but I think this company should consider at least trying to make a trimarans electric yacht. Trimarans travel faster than catamarans and are much safer: and as for energy ideas, I would have put a type of V.A.W.T turbine as they're much more reliable than a regular turbine. Another thing I would add is a water propulsion drive boat. You dont see very much a trimaran yacht in the water and considering that they are faster, stabler, and safer. I think it would be interesting to see if they would do something with this.
One word. Space.
Trimarans dont have allot of living room.
Thanks for watching
I love the boat. It has a great feel and glow about it. My one question is why is the refrigerator outside? Seems like the worst spot to have it.
+Raymond Pugh I think the concept is fantastic. the refrigerator is there just for easy access. I don't think they mind the energy it draws when it's standing outside. guess the solar panels make up for it.
Thanks for watching!
Is it possible to put water turbines under the boat so as the boat goes it makes more electricity.
Yes it is, as long as you pay for it.
Thanks for watching!
Catamaran Channel I wish I could afford it man I have a small business in Canada but I wish someday I buy something like this and sail the world.
Its what most of us dream of i think.
Where the mind goes the body will follow.
does it have to be catamaran style to go solar? cant we have a regular looking yacht to do solar? i just feel a waste of space on the catamaran.
wish the soundtrack was silent.
It is.
@@CatamaranChannel sorry, yep, apart the crap music, totally silent. silly me.
Ant to se this boat,just love it
+TheJustonemore This boat is where the future will be going. Sailing is zo 80's ;-p
Thanks for watching!
Is there a technical limit to the size you could build a solar yacht like this? Could you, for example, build one 300 ft long?
yes we can - please contact me, you finde my email address on our website www.silent-yachts.com
Seems to me this is more of a lake boat, and does not really have the power when rough seas demand it.
i am waiting for the 40 feet solarwave when are the coming out ?
I understand why you are waiting, it might be allot more affordable then the others.
Unfortunately the smallest one out is the 55, wich is going to be available around april/may 2018 with a price-tag starting at €1.270.000.
I also think that it depends how much demand there is and how much room for smaller projects there is on there yard.
And of course on how successful they are in general. (more capital gives more room for other/different projects)
Thanks for watching!
Yeah, shrink this one down just a bit, but keep a lot of the solar panels and batteries. It also doesn't need as many heads, but a nice size master berth and storage space.
yes will be nice cz i can only afford half a million us dollar
I want the 75.. perfect for me..
Me too
Is it possible to add another one or two battery banks to allow closer to 10 knots?
Just curious...what happens if you're doing a transatlantic and gets struck by lightning and power is blown? How long is the lifespan for this solar power system before it would need replaced? I know nothing about solar yachts..
+Justin M Like everywhere else, when your struck by lightning, you got a problem :-) if your lucky.
The solar panels have the same lifespan as any other solar panel with the same specs. Ofcourse over time they will decrease in efficiency, There's nothing "special" about the panels used here, so there as good as the ones that you can buy for any other boat.
Hope that clears it up a little for you.
And if you have any more questions just let me know.
Thanks for watching!
Loved it.
a man can dream...
Can add winds power generators
Why does it have a v bed when the other bedrooms have a full bed?
Is there a way to upgrade the solar panels and add say a Tesla power wall, as tech improves. For example Sunpower makes the highest efficiency panel on the market at about 22% conv efficiency. What are the specs on your panels? Can we swap them for better panels relatively easily?
Alot of not so good looking space consuming furniture in the kitchen and bedrooms...
Also I'd prefer 1 large toilet instead of 3 so i can actually not feel claustrophobic when taking a plunge..
So cheap for so much... does one Lease the batteries or what? how long will they last? Can you Deliver?
batteries come with a warranty of 10 years! Yes, we can deliver - we´re producing three types (55, 64 and 75)
Love it@ MUST buy
Slick idea, but... No sun, no fun. 😅
Does the e come with a sail option?
great technology demonstrator. even better - a sailboat full of flexible solar panels running electric drives could be useful for motor sailing.
avoiding masses of heavy batteries, solar with electric drives would add power at very little extra weight.
she´s good to go already without sails. Why add 1,5 tons of weight, pay 150-200.000 Euro for the rigg, spend a lot of time and money on maintenance - and most of all - produce shade on the panels which would diminish the production significantly and therefore result in a higher fuel consumption? Under "normal and average holiday conditions" the sails would diminish the production of solarpower more than they contribute to the propulsion. Only exemption: really long range cruising in areas with reliable winds like crossing the Atlantic Ocean. But I take any bet, that our Yachts cross the Pacific faster, more comfortable and using less fuel than any other boat of comparable size and comfort. www.silent-yachts.com
I'd want molded carbon handrails above the windows along the side of the haul.
Awesome cat. But the trampolines in black is a no no. You'll burn your skin on that
Jiany Star Massa vich and your pocket!
Thanks for watching!
Look for Bali catamarans if you dont want trampolines.
Bucket list
thank you
11 knots is slow, and I was shocked to read the batteries are drained while it's running with the sun out? How about using some supercapacitors or batteries with supercapacitor technology in series for take-off speed and enabling the use of the sun's energy directly from the panels?
Lithium batteries are on their way out. Graphene? Saline or other batteries? A solar generator as well?
Well, it would be nice for Mr. Musk to buy your company and upgrade production to true Mass Production, cranking out a few hundred yachts per day... 35s, 55s, 64s, and 80s Wind / Solar Hybrid Yachts.
What are those spaces under the stairs?
how about a motor that run on sea water
Vertical wind generator
Silent Yacht 64 .. No it's not. It's a Sola Wave by Serenity
need to learn your camera settings/control for white balance and exposure......
Yes i agree.
Maybe you can tell me a little about it.

Nice boat. Video is less than useful without commentary and a review.

How many bbathrooms are there so far o only see 1
Watch again, there are more.
The measurement unit for energy, for example as stored in batteries, is kiloWatt-hours. A kiloWatt is a unit of power. Power integrated over time is energy. Power and energy are not the same thing. So presumably you mean 50 kWh battery capacity, which would run the combined 50 kW motors at full power for 1 hour. For the size of the boat, the battery pack and motors are undersized. More powerful motors and a larger battery pack would probably be more practical in terms of reaching destinations in a reasonable amount of time. That said, even the smaller motors probably move the boat much more efficiently under electric propulsion than people expect. Electric drive is highly efficient.
Also, while this all seems somewhat esoteric and unusual now, due to falling battery costs, most new (sail)boats and many retrofitted ones will have electric motors and battery packs within a decade or two. As battery costs continue to fall, it becomes cheaper to install electric drive than internal combustion. Electric is about 3x more energy efficient than fossil fuels and vastly simpler, quieter, smoother, more reliable, etc. No cooling systems, no oil changes, no balky transmissions, almost zero maintenance, instant response at all times, etc.
For long distance sailing a fossil fuel electric generator can be added, but for most sailing, solar panels, wind generators, shore power, and hydro generation (regeneration) can charge the battery pack; multiple of those can work while sailing. Electric drive has strong synergies with sailing, particularly due to hydro generation, which recharges the battery pack due to the motion of the boat through the water while under sail.
Probably it's not efficiency of electric motors, but what most people don't realize is how little power you need to move a large boat at slow speed. At least when not going against tide or wind or both at same time. Although electric certainly isn't 3x more efficient than ICE, it's always has high efficiency from lowest to highest rpm. For example if boat runs at different speeds often, electric propulsion and genset might save quite a bit of fuel, if run mostly at same speed there will be barely any difference or even burn more fuel than traditional combustion engine setup.
I will be making electric 30ft catamaran in near future, but i'm doing it only because my planed use and location allows it. 2x15kw and 50-60kW pack, which will allow for modest cruising speeds and some extra power for short periods of time when necessary. And my selected hull is rather light and efficient, most power cats won't go far with this little power. Sadly until energy storage gets way better than currently available, electric propulsion won't go mainstream. Another problem is dealing with high current, while in my case it's still not that big and relatively safe, for larger boats it becomes another problem to deal with.
Thermodynamic energy efficiency of electric vehicles is about 3x that of fossil fuel vehicles. EVs become equivalent in efficiency if fossil fuels are used as a range extender to generate power for electric propulsion over much longer distances than the battery pack can hold. It's actually pretty similar for cars. A BMW 3 series has about 4x more (fossil fuel) energy used per mile than a Tesla Model 3, etc. Same for Hydrogen fuel cells, etc. Plug in hybrids become less efficient as the fossil engine is used for longer distance travel.
Propulsion energy goes up exponentially with speed for a displacement hull, so yes, slower speeds are more efficient.
No one would really run a (reasonably sized) electric motor at full power for a long time if they wanted efficiency. Slower is better, within some ranges of practical speeds.
3x if compare worst engine to best electric and not taking into account any losses for electricity storage and transfer, i.e. not related to actual use. Controllers, charging/discharging batteries, resistance etc all take a big chunk of total efficiency that you didn't include. If fuel doesn't leak anywhere and it shouldn't, engine will burn same amount of fuel you got from your source. But input electricity and what can be used by motor is considerably higher.
And i think can forget about hydrogen fuel cells for a while, round trip for hydrogen is way too inefficient, energy density is really high if can solve storage problems, but that's it.
I'm not even touching source of electricity. Which is yet another topic and is highly depended on location.
3x does take into account all losses including charging and discharging the battery pack, but mostly from automobiles that use highly efficient AC induction or permanent magnet motors and high voltage Lithium ion battery packs. DC motors, low voltage systems, etc. are less efficient, but higher efficiency electric propulsion systems for boats are starting to become more available, and the efficiency of boat electric drives will only improve as automotive EV technology migrates over. The costs will also fall as they have for electric automobiles.
Electric drive on the boat is arguably the most flexible of all. It can use as input energy: fossil fuels via an internal combustion generator, wind generators, shore power, solar panels, hydro generators (regeneration by water flow over the props during sailing), alternator on conventional motor, (currently highly impractical) fuel cells, etc. Several of those are very low Carbon footprint.
How you are getting 3x? A good engine transfers 30-45% as power, the rest going into heat. Fuel from the place it's produced to the point it's used in engine doesn't reduce by any significant amount. First can start with batteries, li-ion has about 80-90% round trip efficiency at best, do any relatively fast charging and this efficiency drops dramatically the faster you charge. Controller then reduces this by another 10% on average. Then PMAC motors are 90-94% and that's one of best ones, brushed motors are in the range of 80-84%. Throw in any necessary current conversions from sources and wiring loss... you still think it's 3x more efficient?
can i get one in toronto on canada
Yes you can.
Beautiful shop, but i would like yo ser the engines; and batteries.
Yes i forgot to film them.
In the next video, there latest build, the silent yacht 55.
I did film everything, including motors and batteries.
Stay tuned!
Thanks for watching!
@@CatamaranChannel thanks to You.
I saw some of these are more affordable than their diesel counterparts and you're not spending as much money on maintenance I just wish I had the money for these maybe my life wouldn't be as miserable
Government killed off the original Tesla creator, he had created a motor that can run forever, only using earths energy. But oil and gas companies didn't like that.
Can you give a link from that motor?
Thanks for watching!
I thank you for the vid, however you did not let us get a good look at the motor. Trying to sell someone on electric motor and not be able to see it is a downer.....i feel like i wasted some time watching this.
You are right.
I did it in the other video and i will do it on every other e-catamaran i visit.
Thanks for watching!
It's a bit squeeze for me like one of those midget subs !! 😸
nice concept, but still not good enough.
Not designed for regular circumnavigation, so it is just another weekend boat.
makes me sad, would have loved to see it as a world cruiser, but I guess technology isnt there yet
Oil smells funny :)
No doubt it is innovative as wall as it's price... I would buy 3 Amel 50'' boats if I had that much in my pockets.
I dont think a full fitted amel goes for 500k.
1000k will get you one, if im correct.
Thanks for watching!
Clicks on video hoping for an in depth review of the boat. One second in and the trademark irritating you tube channel music starts up. 🙄Immediately heads back over to Aquaholics channel.
Was ist bei Wassereinbruch? Man sieht keine wasserdichte Schotten!!
Of course she has watertight sections - there are another 5 meters in front of the master cabin and about 4 meters behind - absolutely weatertight sections. BTW - ask and better check other cats for that, you would be surprised!
Why not add small propellers under the boat that generate additional electricity when you are driving the boat, simple way to increase zero emission range
App Magician that does not work. Goes against physics. Sorry
Damn the interior styling and format was disappointing. Needs an upgrade there
Its all custom, so whatever you want they put in.
