Thanks for doing more, these boats are amazing. I really want to consider this as my first real purchase. It’s about the adventure not the speed of which you get there.
as a person TOTALLY NOT into the solar buzz I must admit because of your series on the Silent Yachts I am becoming more and more a fan of this solar solution, Starting to love it
Thanks David, the topics are always complete and detailed. With the possibility of following the project over a long period. For the quality of the video, this is the best. 👍👍👍
While I may not be a part of the yacht buying public, I do make a point to stay up to date on this brand and their products. It is a highly interesting application of solar technology and I truly hope this company continues to succeed.
Silent Yachts cost even less when you factor in all the maintenance and repairs the boats DON'T have - Check Engine Light costs, Oxygen Sensors, Timing Belts, Oil Changes, Oil Filters, Coolant Flushes and Thermostats, Gearbox Services, Leaking Gaskets, Bad Injectors, Spark Plugs, Coil Packs, Ignition Wires, Diesel filters and clogs and various other Engine Sensors. On average, over a ten year ownership that's several THOUSAND dollars EVERY year. Silent Boats - zero $$$
As an engineer, I want to like it, and I'm glad someone is taking on the challenge to make yachts greener. It could work well for owners that do not go too far at a time, but they are trying to represent it as an ocean going yacht with unlimited range, which is highly irresponsible. While the numbers differ for the different sizes, it's the same basic story. Take the 60 as an example, using info from their website, the solar panels are 16kWp (peak, meaning optimal conditions, no clouds), while the smallest motors are 2x50kW. Now if you cruise at 5 knots, they are probably operating at a fraction of that capacity, but then you have to run the a/c, navigation, all appliances, and charge the water toys on top of it, and all from that 17kWp input. The solar panels are just not capable of supplying all the energy needs in that scenario. There's a reason they have a 150kW diesel generator onboard, and a fuel capacity between 600-1600L. So if you are doing more than a few hours of cruising a day, the generator will likely need to kick in. For owners that will use it once in a while to take shorter cruises around the coast, it's probably perfectly fine and will vastly decrease fuel consumption and carbon footprint, and may even be zero emissions. But to use it to cross oceans, you'll probably not be doing more than 60 to 80 nm a day in good conditions, and you'll likely run out of supplies and put lives at risk. I love the concept, but it will only take one owner that has an incident while making a crossing for the media to jump all over this, and that will put the whole concept of clean solar yachts at risk.
Hi Ethan, I interviewed the owner on my other channel (you can see it at th-cam.com/video/T8FCZzRCQVk/w-d-xo.html). Im hoping to interview him again soon on this channel so your comments would make for an interesting discussion.
Hi Ethan, I truly understand the piece of this yacht is not 100% green at all, that the gen will be running for long periods to recharge the battery bank, and there will be days it will be running constantly. But as a sailor that’s the same concept for not having winds while in a sailboat, you’ll have the need to motor sailing and have the gen running. In regards of running out of supplies, well the question I have is, have you done long passages? because the probability to run out of supplies on this yacht would be the same you’ll have in a sailboat, which for those that have done long passage is very uncommon .
No to attack you, but it's clear you're not a sailor. For 3 months a year, I am an Alaskan Fisherman in Bristol Bay. In a 32 ft long 18 ft wide gillnet boat, I easily store supplies for 3 very hard working fishermen, for 21 days at a time. We eat roughly 3 times what we normally would when we're down south, as down there we're not working nearly as hard and not needing the extra energy to keep warm. Passage from Anacortes WA to Hawaii at 5 Knots would take about 21 days. And after running some hull calculations it would require 15kW to propel the vessel at this speed. So (2371.91 / 5)*15kW = 7,115.73 kWh of power to get to Hawaii. (26 kw solar * 12-dy)*21 days = 6,552 kWh generated b the panels. A deficit of 563.73 kWh for the entire trip. Genset hours for the trip: 3.75 All the other electric demand on board, including the AC, would add at most 630 more kWh of demand, bumping my total gen set hours to 8 for the entire trip. Using roughly 367L of fuel.
@@davidblalock9945 As stated, I'm an engineer, nowhere did I claim to be a sailor. I'll take your word for the calculations above, but common sense would dictate that between Washington and Alaska, you would not get anywhere close to the peak output of those solar panels for 12 hours a day, every day for 21 days straight. And it's not about how much food you can pack onboard, but how much is actually taken on by the one planning the trip. You can also easily make stops on that trip, as you are not too far from the coast at any time. Whereas I'm talking about a true ocean crossing, Atlantic at a minimum. Like I said, it only takes one incident and the media will be all over it. I'm not a sailor, but neither are "journalists" that will sensationalize a tragedy and destroy the whole concept just for a few more views and clicks. See early and even some current coverage of Tesla cars, for example.
I just want to clarify that I am not against this concept, the yacht, or the builder. I want them to succeed. My objection is only about their representation about the boat as an ocean crossing vessel with unlimited range, that might get some new yacht owner killed because they might plan for a few small delays, but any sailor knows the weather can be unpredictable and often uncooperative. As an analogy, I raise the same issue with Tesla auto pilot. I like and want electric cars and Tesla to succeed, but it's irresponsible to market the autopilot as some self driving miracle, and people have been killed because they were too reliant on it.
Interesting to see how some of the comments are very similar to EV sceptics. But when you take them for a ride in a Tesla, they all want one. Change is difficult for many people to accept.
This is more like PHEV, not EV. I believe these are bought by experienced owners who figured out their own use case and decided one of the Silent models will fit them. Or willing to accept some adjustment to live with its limitations. For me, this is a brilliant solution as long as one does not like to go fast. Makes lot of sense.
Love the 80. The power gen/consumption is still confusing even after watching all vids. Question: With the mid choice of battery/motor choice how many knots can the 80 do in calm seas with full sun ☀️ and no ac, but have avionics and fridges going. In other words how many knots 4-6? On solar. Solar with bats. And how long. 2hours? 8hrs. Full sun no generator
Their website claims 17kwp panels can generate about 100kwh a day. Enough got a silent 60 to travel 125miles (no speed mentioned but I reckon about 5knots) and it also covers all the aux draw. Silent 80 has 26kwp panels. I'd imagine similar all electric self sustaining range to the 60 model.
@@TsLeng Thanks, The CEO says that its about the same as sailing speeds 4-6knots. But doesn't elaborate too much. Too bad he's not interested in more panels that slide out on actuators, locked in place with poles to protect against winds. Just like yacht have awnings.(as an example +5 panels in front, +5 in aft, +3 per side, I did the math) That could bump up generation to 46-50kwp, and maybe a speed of 10-12knots without AC and generator. That would be the wholly grail.
@@Paul37Ontario that will add complexity and weigh I guess. At it is, it is pretty good and even if you have to use a bit of diesel during the day to hold some charge for night aux power (complete silence without generators) it isn't the end of the world. Really suits trips that have lots of anchor time too. With the biggest battery at 400kwh, one can even sail through a night on battery.
@@TsLeng I see your point. My point is that doing the math it would just add 400-600 kilos, on a 80 foot vessel that's like 8-10 people, not any weight to talk about. And at a cost of 6.5 million I would expect the most effort or some other manufacture will do it.
@@Paul37Ontario you have a point. I am thinking also if overhanging panels will negatively impacts aesthetics and shade more of the boat which might not be desirable for the occupants. After all , people want to sunbathe, look out at scenery etc. Apparently they do have a kite sail system which helps for long journeys. Not sure how well it works but if it does, that solves the problem of non fuel range
I just discovered this video. Wow! The Silent 80 looks like the Tesla of Yachts. Simple. Clean. It even outshines Elon by using clean solar to charge the batteries. I'm impressed. My one concern is, how has solar energy advanced over the last decade? Solar cells seem to still be rather inefficient.
Boaters are not looking for environmentally friendly boats. This is an assumption. Boaters are looking for independence from land, from people, from repair and foremost from petroleum! Your assumption that boaters want environmentally friendly boats show you don’t know your market in the least.
Hydrogen would make a better generator than the diesel they currently use. That can be achieved very soon as there are already hydrogen powered cars. That would make it truly zero emissions.
@@Ethan7s till they perfect hydrogen storage its a non starter just like it always has been. and hydrogen production has never been zero emissions. no "green tech is completely zero emissions. take your trolling elsewhere man
@@TheCort1971 Several car makers have been offering hydrogen powered cars for years, so commercialization has already begun. Don't project your ignorance onto me as trolling.
@@Ethan7s and not a dam one of them is selling. Dont even try it troll boy. Its a non starter. Trying push that sloppy bs all the while trying say that battery power is good enough. Back to the hole you crawled out of troll
I don't think it's the environmental friendliness that's the reason. It's total freedom, you never have to worry about diesel or anything else. If you have a desalination device and a fishing rod, you can stay on the water until the motors give up.
I couldn't agree more. These yachts enable peace of mind in its purest form. I always hated the idea of having to run a generator at anchor even if you just wanted to microwave a bag of popcorn. Making every single resource onboard renewable and basically free is amazing.
Absolutely right. I've never believed in or cared much about the global warming lie, but I've been a major proponent for so-called renewables for the very simple reason of fuel availability. These boats exemplify the very concept. Freedom from burning fuel. The near complete removal of maintenance requirements on diesels is just compounding that fact. I'd be perfectly content cruising at 5kts so long as I also have the ability to run at 15-20kts to avoid weather when needed. These two have clearly thought about what matters.
A great company and people behind it. Also a great watch, really enjoyed it thank you

Would love to see more silent yacht videos.
You should built silent 100 with XPeng 2 landing in the front and big jacuzzi on the 2nd flloor, with BYD batteries to avoid fire and faster charging.
Looking forward to the layout videos.

Hello and a Happy New Year ! When do you think you will make a complete video tour of a 80 Silent ? Thank you and best regards, keep the good work.
Would love to see a walk through of the 120!!!
Excellent Boat
Would love to see a kite assist model come out.
Optional
Nice
