This tech would actually be decent for house boats. For the most part they arent moving around all that much so over the course of a day you'd supply all your power and be able to charge the batteries so when you want to move the boat around you've got the power to do that.
With a house boat, you could also have wind turbines, for when the house boat isn't moving. Perhaps they collapse when the boat is moving, and then you raise them up when the boat is anchored, so you're generating power from the wind as well.
I thought of that too, but a lot of area is lost and even sun area is shaded, when using sail. You are better off (I believe) using more solar panels, and a new "Sharrow" propeller which is 36% more efficient, that I don't see mentioned often on these shows. Imagine that! For the rest, you can have high-concentration solar panels, with external fennel lenses and internal high-concentration solar cells, that move on the inside to capture every angle of the Sun. Cooled by sea water, which can be used in a heat exchanger to heat internal water, or for radian floor heating. Imagine capturing 50% more energy (by maximizing efficiency at different angles of the Sun, having more efficient and cooled panels, and capturing the heat). While also having a new Sharrow Propeller for maximum efficiency. You could literally cross the OCEANS! At no further cost.
1. The weight of EVERYTHING on this boat matters and that's why SY have been fanatical about weight reduction and friction reduction. I've seen the extended hours-long interviews with the designers. 2. Yes there is. It's called cloud cover. We get it months a year in the Northern Hemisphere. 3. A true wind sail interferes with the solar collection, but they DO come with Kite Sails to help.
The benefit of a boathouse is the weight doesn't matter if you compare it to a trailer. Weight matters only if you want to travel fast, but not if you live on the boat.@@darthkek1953
You understand nothing about physics and engineering. Weight "doesn't matter" when you're floating in the water, but it ABSOLUTELY matters when you're trying to propel *_TONS_* of weight through the water! But it's obvious that you've memorized all the sales pitch lies. Lol Silent Yachts just filed for bankruptcy because customers are finding out that the performance doesn't match what they were promised. Diesel/electric hybrids are the only reliable option currently available! Which is why Greenline Yachts can't make their hybrids fast enough to meet demand, but Silent is going out of business! If solar was a viable option, they would be selling them faster than they could make them.
It’s a cool thought you can possibly travel the world in one of these and never have to refuel. I’m sure it’s not practical yet but it’s a dream I’d love to live.
Plenty of people already doing this with normal sailing yachts or sailing yachts with electric conversions. Sailing Uma is a great YT channel that’s doing this already for a price range available to the middle classes if you wanted an example.
Cool video article. I wish there was more talk about the technology from the perspective of plug-in yachts and where the megawatt charging system (MCS) will fit in the industry.
It’s so stupid we didn’t have solar electric yachts sooner. The sun has always been there. True energy independence. We got suckered into paying for oil.
Seems silly to not also have wind turbines which could be used when the boat is anchored and at night. They could lie flat, and then you push a button and they rise up and start generating wind power. Or it could even be an automatic thing, if the boat is idle for more than a few minutes, they just automatically pop up and start working.
It's because wind isn't as efficient lower down and moving parts that raise and lower a mast is a cool bit of boating callback, but hardly an efficient use of space or a reliable mechanical part on the water. There's a reason offshore wind installations are MONSTERS.
They (Silent-Yachts) make a huge kite sail that they run from the bow that does help if you are going to be sailing for long enough to warrant the hassle of deploying it. Wind turbines are kind of noisy and don't really put out enough power to bother with.
@user9b2 What is the benefit? Tell us where the nearest hydrogen filling station is to every port in the world? LOL, dum dum. Or does your wishful thinking create hydrogen filling stations worldwide??????
@@bftjoeyou are the dumb dumb here! Hydrogen can literally be produced everywhere around the world using even renewable energies sometimes excess of energy and also searchers are working on a much better hydrogen storage solutions...

I am all up for electric transportation. And these boats are great! But they always avoid mentioning the cost of replacing the battery bank, which is a huge cost. With time, batteries will improve and become cheaper. But for now, you must consider that HUGE replacement cost, which will inevitably come.
@gse3862 You need to do some research on how often batteries need to be replaced and the cost. I think you will be surprised. As far as I can tell the batteries will last longer than I will if treated right and the cost is half of what it was 6 years ago. TCO should be much less then the diesel you would have burned.
Also the new Sodium Iron batteries that CATL has produced, when improved, might even be way cheaper and more environmentally friendly. Last longer and have more power. The only draw back is energy-density, but even that is set to improve and is only an issue for cars. For boats, they are ideal, as they last way longer and are way cheaper.
Interesting concept. Imagine if they put solar panels on top the Staten Island Ferries. That would save New York a huge chunk of change in fuel savings.
Easier to just switch to electric with huge battery banks that you plug in at the dock. They could fill up over night and then just get topped up at every stop. I think that is what the Swedish ferries are doing.
Too much weight and drag. The only reason these catamarans work is they have slim catamaran hulls and everything but everything in these vessels is weight concisions. MDF tables instead of glass ones. Plastic shower cubicles. A ferry? Solar panels would provide a millionth of one percent of the power required.
It's a term from the 1920 to differentiate bog-standard yachts and the one-off huge yachts of the mega rich. These are yachts, they are NOT superyachts.

The biggest breakthrough will be solar sails, it's patently stupid to be on the ocean and not make use of the wind. Solar sails will aid in propulsion, and will the electricity needed to run the systems and the motors when needed.
Look at the use of these. They mostly float around the Med, don't move far and then just anchor for a few days while the owners drink/swim/fornicate. You don't need sails for that. Also the learning curve between motor yacht and sailing yacht is large enough that these people don't want to learn how to hassle with sails. Personally I'd go for a sailing catamaran like a HH50 with lots of solar and batteries. I could mostly sail around the world and use diesel when needed.
I've been saving up for my Silent 60 for years... someday I'll have one. I would never consider a gas or diesel boat. That would be like buying a new gas car in 2023... why would anyone want to do that? LOL
SY are diesel by stealth. They come with generators and huge tanks and you'b be a madman to think you won't be using it. It's LOW diesel (only in the sun) but it's not NO diesel.
I work for a Shipping company and i can say it is not possible to make Cargo vessels working only on electric motors because you need a lot of power. They are all to waek. For smaler Ships like Yahts or Small ships that dont travel far it is ok but not for cargo. We are looking for alternatives but there are not much. The next gen. of Cargo ships are going to be probebly bio Diesel or hydrogen when the engines are going to be stronger. And dont forget, the old Ships are nasty asf. But the new ones are very eco friendly compared to the old ones
Powerful? Aircraft carriers have 100% electric drive trains. :) You are right though, you couldn't put on enough solar or have enough batteries. There has been some intresting talk of kite sails and tall spinning tube sails but I dont think those will work well on container ships. Maybe on oil ships (irony?) or bulk cargo with their mostly flat decks.
Absolutely. The only reason SY work iss they are low-drag narrow catamaran hulls and SY were FANATICAL on weight and drag reduction. Plastic glass in the showers and MDF tables.
Superyachts? Mooring fees, maintenance are understandable for the working person or company, but non-liveaboard cruisers have other needs. What’s happening with solar driven smaller yachts in the 30-40’ range?
Advertising and Reality are different. In the brightest of Sun these can drift around fractional speeds. But the reality is they get charged at dock and then they run generators. Oh, didn't they mention each hull has a generator? When the Silent 55 was the first "solar electric" boat to cross the Atlantic an interview with the captain (an experienced Spaniard) said he kept the generator running 24/7 to get enough energy to cross in time.
In the brightest of Sun you can power at the same cruising speed as most other boats without using the diesel generator, While using all comfort needs. It was the Silent 64 that sailed across the Atlantic and he ran the generators for 3 hours at a time because, he was in a storm that lasted a week, with waves as high as 10 meters. He also stated that the solar was still collecting small amounts of power during that time. It looks like it did what they said it would do. Success Story. @darthkek1953 Why be so afraid of Solar? Come on in the future is looking bright.
@@darthkek1953 right, and the hard part is the batteries but if batteries were cheaper you could have the drive engine be electric without any gas or diesel at all. Usually you use the wind anyway so it wouldn't take much electricity used very rarely.
They're not megayachts they're not superyachts they're yachts and they're not zero emission (they have generators on because the sun, frankly, is rarely enough alone).
For a catamaran, solar can make sense. The ship is relatively light weight, it does not have as much drag on the water, and it has prolonged periods of rest while at port. Integrating solar panels doesn't make too much sense if the ship is meant to last more than 25 years. It means the ship will effectively be a waste product in 25 years. Unlike a steel boat, the fiberglass boat will also be more difficult at end of life. The solar panels will also have issues in both hot and cold environments. The batteries don't do well in the cold. The panels don't do well in the heat. For larger vessels, solar won't work. These vessels are constantly at sea, so they don't have those long periods to recharge batteries. It may help with crew conditions while waiting in queue at port. Nuclear is an option for the exceptionally large vessels, but decommissioning will be an issue and I don't think those vessels will be on the sea for over 50 years. One thing that is possible is to use an electric engine that is powered by both solar and diesel. There are periods where the diesel engine works less efficiently to maneuver or change a ship's speed. If it was possible to use electric power here so the diesel engines could be run under optimal efficiency, then the overall efficiency increases. But physically it may not be worth it.
Interesting points, solar wont be sufficient to fully replace combustion engine power but it can certainly improve the running cost by reducing the amount of fuel needed for voyages. Presumably the reduced fuel saved by solar would allow for greater loading capacity also, since cargo ships carry huge fuel loads as well.
Yeah because you never spend another dollar on your super yacht after buying it. Fixing solar panels after 20 years is definitely a deal breaker. Before you know it our landfills will be full of super yacht solar panels. 😂
Silent Yachts just filed for bankruptcy because buyers have found that the performance doesn't match the hype. I'm really looking forward to when solar is a viable option, but until then. Diesel/electric hybrid are the most reliable clean option. Which is why Greenline Yachts can't make their hybrids fast enough to meet market demand and why Silent is going out of business.
Not everyone can or wants to sail. It's a high-skill physical discipline. (And besides, loads of sailing boats have their generator on for the fridge, navigation and of course the A/C)
The only negative I have, is these solar powered yachts don't seem to have the sleekness of a conventional yacht. It seems that a lot of these yachts are too boxy in design, which IMO, really detracts from their overall aesthetic appeal.
They are not considered hybrids in yachting because that has its own definition and companies like Greenline are in that niche. But they ARE hybrids in reality. Their generators are connected to the batteries and you can top the batteries up faster than the engines can drain them. In fact the Silent 55 that crossed the Atlantic had the generators on 24/7
The generators are indeed run often. But if you go port to port, or port to cove to port, depending on the weather and speed you choose you might be able to get away with not using them, or only briefly. But in fairness other "normal" boats would have their generators running 24/7.
The point of these yachts is not to appease a grumbly witness. The purpose of these yachts is to drift, silently, into a cove where you and your family and friends have a vast private Island Oasis.
It's not about distance, it's about speed. The faster you go the EXPONENTIALLY more energy you use. If you drift around at displacement speed, don't use the A/C and have good sun, you can have unlimited mileage.
sorry to say this ,but eco should be fully no negative impact on environment in long term also and these solar panels and lithium batteries are not recyclable after some time and it will be hard to us to stay with that.
Those yachts are definitely NOT "powered by the sun"; that area of solar panels would barely run the AC and icemakers. Boats like these use about 1-2 liters of diesel per km of travel; there's zero chance you could cruise the Med on solar power. For example, on the Silent Yachts website, the fuel capacity is 1000L to 1900L, hardly silent.
Yes and no. If you charge at dock you run on battery at very slow to a cove, if you don't run A/C and stay at a cove a day or two then you might get enough charge to return to dock. It's not impossible. But for passage making yeah you really do need the generators on several times a day. HOWEVER thanks to the large batteries MUCH of that journey is Silent if you're going cruising not racing speed the generators fill the batteries much faster than they are drained, so you fill the battery (up to whatever level) and then turn the generator off. If you're doing a high-speed dangerous passage-making (e.g. Atlantic) then that's when you have them on 24/7.
Yup because the environmental problem with super yachts is their fuel consumption -_- I would bet that a yacht with a bunch of solar panels on it has higher carbon cost to make then the carbon cost of a median humans entire life...
Yes and no. I say yes but they don't claim it directly because Greenline hybrids (the first boat hybrid brand) do it differently and they didn't want to claim an unclaimable overlap.
would be nice if they would make those vehicles that can take water to make hydrogen and electricity... ideal for yachts as they can take sea water where theysail...
What would be the purpose of that? It takes energy to split water into hydrogen and oxygen, so there's no energy savings. The only difference is that you'd be storing energy in hydrogen gas, rather than in batteries. But seems a long (and expensive) way to go just to store energy differently.
They are CE Cat A rated which is the highest level of specification. That is they're rated to go Blue Water, trans-Oceanic, and are rated to withstand any storm short of a named Hurricane.
Yeah but 2M+ for just one is dang expensive. Let see that base catamaran only around 700K max because is new then you install solar which add up to 1M+ which is reasonable prices but no they charged labor works too. Nothing is free in this world.
Green washing at it finest. That "back-up" diesel generator is what's doing the real heavy lifting here. Those solar panels won't even produce enough power to run the ships accessory systems, let alone the propulsion. A couple hours out from port and those batteries will be dead and 99% of the energy will be coming from fossil fuels. Even if they could magically power the entire thing on solar, lets not forget the massive environmental cost of building these ships before they ever touch the water.
Maybe solar yatchs can have a sail or giant kite for cloudy but windy scenarios. Regardless, this is just greenwashing for few rich braggarts with minimal impact.
Tipical modern information. You get all ecconomic informations (which you didn't ask for) and none technical informations. Speed, range, autonomy, how doesi t function, what about if there's no sun tc., etc...
Speed is up to 18 knots, range is dependent on speed but at displacement and in the sun, without A/C, pentially unlimited. After that, balances. If there is no sun or you run low, there is a generator connected to the batteries. So you top it up with diesel.
solar/electric is the 8 track tape of energy....the main problem is batteries and because of this it's just a stepping stone....to......fusion power that is the future of energy.....safe, constant, on demand power, with no storage needs...
Not true. I mean, yes if you're going at speed you'll be using the generators. But if you don't use the A/C then these panels will run both hotel (fridges, etc.) and engines.
From the pic ，there is not enough PVS to push it go fast. For the inverter it should apply the IP65 in this area. Currently it' a aux part but it's green.
This tech would actually be decent for house boats. For the most part they arent moving around all that much so over the course of a day you'd supply all your power and be able to charge the batteries so when you want to move the boat around you've got the power to do that.

It was the Silent 64 that sailed across the Atlantic and he ran the generators for 3 hours at a time because, he was in a storm that lasted a week, with waves as high as 10 meters. He also stated that the solar was still collecting small amounts of power during that time. It looks like it did what they said it would do. Success Story. @darthkek1953 Why be so afraid of Solar? Come on in the future is looking bright.
There's very few technologies as good as sailboats. A solar electric/sailboat would be an awesome boat!
Most sailboats these days have solar panels on them.
@@darthkek1953 right, and the hard part is the batteries but if batteries were cheaper you could have the drive engine be electric without any gas or diesel at all. Usually you use the wind anyway so it wouldn't take much electricity used very rarely.
silent yachts went bankrupcy
The fact the term zero emissions was used even once in a video about mega yachts is the definition of irony.
They're not megayachts they're not superyachts they're yachts and they're not zero emission (they have generators on because the sun, frankly, is rarely enough alone).
Someone get the narrator a drink of water! Her vocals are frying!!
For a catamaran, solar can make sense. The ship is relatively light weight, it does not have as much drag on the water, and it has prolonged periods of rest while at port. Integrating solar panels doesn't make too much sense if the ship is meant to last more than 25 years. It means the ship will effectively be a waste product in 25 years. Unlike a steel boat, the fiberglass boat will also be more difficult at end of life. The solar panels will also have issues in both hot and cold environments. The batteries don't do well in the cold. The panels don't do well in the heat.
For larger vessels, solar won't work. These vessels are constantly at sea, so they don't have those long periods to recharge batteries. It may help with crew conditions while waiting in queue at port. Nuclear is an option for the exceptionally large vessels, but decommissioning will be an issue and I don't think those vessels will be on the sea for over 50 years.
One thing that is possible is to use an electric engine that is powered by both solar and diesel. There are periods where the diesel engine works less efficiently to maneuver or change a ship's speed. If it was possible to use electric power here so the diesel engines could be run under optimal efficiency, then the overall efficiency increases. But physically it may not be worth it.
Interesting points, solar wont be sufficient to fully replace combustion engine power but it can certainly improve the running cost by reducing the amount of fuel needed for voyages. Presumably the reduced fuel saved by solar would allow for greater loading capacity also, since cargo ships carry huge fuel loads as well.
Yes, solar panels are impossible to replace. LOL
Yeah because you never spend another dollar on your super yacht after buying it. Fixing solar panels after 20 years is definitely a deal breaker. Before you know it our landfills will be full of super yacht solar panels. 😂
You just made up 95% of that.
Steel hulls would be a terrible choice, aluminium hulls on the other hand would be smart thinking.
DiLithium Crystals when?
Silent Yachts just filed for bankruptcy because buyers have found that the performance doesn't match the hype.
I'm really looking forward to when solar is a viable option, but until then. Diesel/electric hybrid are the most reliable clean option. Which is why Greenline Yachts can't make their hybrids fast enough to meet market demand and why Silent is going out of business.
They should. 👍
Its maybe a bit out of the box thinking but why they just don't use wind as propulsion?
Sailing is a lot of work. Some people want more relaxation/ less effort.
Not everyone can or wants to sail. It's a high-skill physical discipline. (And besides, loads of sailing boats have their generator on for the fridge, navigation and of course the A/C)
The only negative I have, is these solar powered yachts don't seem to have the sleekness of a conventional yacht. It seems that a lot of these yachts are too boxy in design, which IMO, really detracts from their overall aesthetic appeal.
From the outside, yachts beat catamarans. From the inside, catamarans beat yachts.
What's wrong with hybrids? What would you do if you're stuck in a storm? The onboard generator could not keep up!?
They are not considered hybrids in yachting because that has its own definition and companies like Greenline are in that niche. But they ARE hybrids in reality. Their generators are connected to the batteries and you can top the batteries up faster than the engines can drain them. In fact the Silent 55 that crossed the Atlantic had the generators on 24/7
With solar panel efficiency almost double over next 18 months thanks to china these yachts are the future
I wonder how much fuel is planned for the generator to run.
The generators are indeed run often. But if you go port to port, or port to cove to port, depending on the weather and speed you choose you might be able to get away with not using them, or only briefly. But in fairness other "normal" boats would have their generators running 24/7.
Imagine a battery catching fire
Better idea, get rid of superyachts
Boys must have toys
I didn't know this was a channel for the poor complain in
Get rid of the super yacht owners 😉
Envy is such a bad trait
Disparity of wealth is amazing.
What about a sail made from solar panels?
Angle of the sun means little collection.
Yatcht is a must have to show your class and stature
Absolutely. Sure. Now go finish your homework and go to bed.
Yachting is now more affordable for wealthy
You still probably want a gas/diesel backup engine.
They don't offer a diesel engine but every SY has a generator connected to the batteries. So it's really hybrid.
How do I get to be rich explorer and adventurer? Im from Detroit😂
Have you thought about a wind powered yacht...?
Bezos yacht is sail -ish
those era some beautiful yachts, with all those solar panels 😂
The point of these yachts is not to appease a grumbly witness. The purpose of these yachts is to drift, silently, into a cove where you and your family and friends have a vast private Island Oasis.
Is there a risk of the batteries catching fire or exploding?
Like diesel?
Thermal Runaway
@@HardstylePete diesel is a low fire risk. It doesn't explode and is relatively difficult to set alight. Petrol/Gas on the other hand... BOOM!
did they mention how far boat can go?
It's not about distance, it's about speed. The faster you go the EXPONENTIALLY more energy you use. If you drift around at displacement speed, don't use the A/C and have good sun, you can have unlimited mileage.
Question is, can they sink?
I sure hope they are very sinkable.
@@piku5637envy doesn't look good on you 😂
No ship has ever sunk so it's not likely to be the first ever one.
Nuclear powered vessel would work much better like they use on aircraft carriers. Those boats can run for decades
sorry to say this ,but eco should be fully no negative impact on environment in long term also
and these solar panels and lithium batteries are not recyclable after some time and it will be hard to us to stay with that.
Those yachts are definitely NOT "powered by the sun"; that area of solar panels would barely run the AC and icemakers. Boats like these use about 1-2 liters of diesel per km of travel; there's zero chance you could cruise the Med on solar power. For example, on the Silent Yachts website, the fuel capacity is 1000L to 1900L, hardly silent.
Yes and no. If you charge at dock you run on battery at very slow to a cove, if you don't run A/C and stay at a cove a day or two then you might get enough charge to return to dock. It's not impossible. But for passage making yeah you really do need the generators on several times a day. HOWEVER thanks to the large batteries MUCH of that journey is Silent if you're going cruising not racing speed the generators fill the batteries much faster than they are drained, so you fill the battery (up to whatever level) and then turn the generator off. If you're doing a high-speed dangerous passage-making (e.g. Atlantic) then that's when you have them on 24/7.
Imagine if it could use water or wind to generate power....
Like a sail?
Yup because the environmental problem with super yachts is their fuel consumption -_- I would bet that a yacht with a bunch of solar panels on it has higher carbon cost to make then the carbon cost of a median humans entire life...
What was the carbon cost for you to make this useless comment?
@birdness idk ask Google, they could tell you I'm sure.
Useless bet, show numbers, or shut up.
Really, there’s no need to destroy the environment while trying to enjoy it 🤔
Polish maker is really really cool. The Austrian giggollo saying that he is Tesla of the sea is a Mickey Mouse.
Very good 👍❤❤❤❤🎉🎉🎉
So these boats are hybrids.
Yes and no. I say yes but they don't claim it directly because Greenline hybrids (the first boat hybrid brand) do it differently and they didn't want to claim an unclaimable overlap.
Cost about the same as a house in cananda lolzz
would be nice if they would make those vehicles that can take water to make hydrogen and electricity... ideal for yachts as they can take sea water where theysail...
What would be the purpose of that? It takes energy to split water into hydrogen and oxygen, so there's no energy savings. The only difference is that you'd be storing energy in hydrogen gas, rather than in batteries. But seems a long (and expensive) way to go just to store energy differently.
@@enargins and there are losses at each step. Hydrogen rarely makes sense in transportation. Storage is way too large for most mobile uses.
Are they any stronger than other superyachts?
Doubt it. They still haven't made trucks to pull cargo strong enough yet(at least 5 years they did have them. Haven't seen any yet really)
They are CE Cat A rated which is the highest level of specification. That is they're rated to go Blue Water, trans-Oceanic, and are rated to withstand any storm short of a named Hurricane.
who travels to other countries in ships these days?
People who get cruises?
Sailors.
Yeah but 2M+ for just one is dang expensive. Let see that base catamaran only around 700K max because is new then you install solar which add up to 1M+ which is reasonable prices but no they charged labor works too. Nothing is free in this world.
Very good prices for same-size motor yachts. Sailing yachts are cheaper but require much more skill and huge amounts of labour to work.
Green washing at it finest.
That "back-up" diesel generator is what's doing the real heavy lifting here. Those solar panels won't even produce enough power to run the ships accessory systems, let alone the propulsion. A couple hours out from port and those batteries will be dead and 99% of the energy will be coming from fossil fuels.
Even if they could magically power the entire thing on solar, lets not forget the massive environmental cost of building these ships before they ever touch the water.
Lithium and water dont get along well .. if there is failure in the battery, the whole yacht going to burn
They'll make good reefs
Sails 🥱
Sailing is hard work and requires skill.
Maybe solar yatchs can have a sail or giant kite for cloudy but windy scenarios. Regardless, this is just greenwashing for few rich braggarts with minimal impact.
They do have Kite Sails.
they can go electric if they install a nuclear power plant inside it. otherwise no way. they consume too much
Tipical modern information. You get all ecconomic informations (which you didn't ask for) and none technical informations. Speed, range, autonomy, how doesi t function, what about if there's no sun tc., etc...
Speed is up to 18 knots, range is dependent on speed but at displacement and in the sun, without A/C, pentially unlimited. After that, balances. If there is no sun or you run low, there is a generator connected to the batteries. So you top it up with diesel.
I file this under things I don’t care about and things I’d never want to own even if I was super wealthy.
Not everyone is a millionaire
Probably good beause SY can't scale up to make one per person.
solar/electric is the 8 track tape of energy....the main problem is batteries and because of this it's just a stepping stone....to......fusion power that is the future of energy.....safe, constant, on demand power, with no storage needs...
Cant be long before one of these is blown sky high by exploding batteries, as they commonly do with electric cars.
Forget Super Yachts. Just give me all the excess money you don’t need. 🤑
Fly to your port with private jet burning jet fuel.
just get a sail.....
can't stand her vocal fry!!
I though that trend went away already
If its Gods money then man wrote the Bible not god
Greenwashing
That amount of panels barley can power the inverters. This is a scam
Not true. I mean, yes if you're going at speed you'll be using the generators. But if you don't use the A/C then these panels will run both hotel (fridges, etc.) and engines.
From the pic ，there is not enough PVS to push it go fast. For the inverter it should apply the IP65 in this area. Currently it' a aux part but it's green.
Such a gimmick to placate common man's concern
Turkey really! Move your manufacturing to another country.
Turkey is a world leading yacht and superyacht manufacturing zone. Surprising to hear, to some.
I DON"T CARE CNBC
