It's nice to have but limited to their power usage! Only for short distances. But for practical voyages .. impossible and very unreliable unless they use more advanced technology to harness power

@Dumb how long it took them? 60 days at max 5knots?

@@nr3059 I dont understand the willful ignorance. Plenty of information to show that its perfectly viable for long distances. Is it the best option if you are looking to cross the Atlantic in the shorted time possible? No. Is it one of the more comfortable? Yes, probably.

@@SuWoopSparrow Your only source for moving is Solar as an energy storage. Get stuck in a boiling sea with no sun light ... Wishes doesn't safe life! 5Kn is slow in comparison to many other boats. The min. in my opinion should be 8kn not less .. Ignorant to ignore facts!

@Sabar sabar What does any of this have to do with the fuel technology of a boat? Any boat of a similar size will have issues with those things. Anyways, Catamarans are more stable than boats of similar size, so if anything this will do better than many other options.

Fully agree - his dedication is truly admirable!

with 3D-printing you will be able to reduce a large amount of the producing cost. but in a few years it will be much better due to better batteries

Yes in only a few years everyone will be able to afford an 80 foot long luxury yacht! Eat the rich.

@@bial12345 "and when everyone is super, no one will be" _ Syndrome

@@Humbulla93 I do not think 3D printing will be that useful. Pretty much all 3D printed objects suffer from decreased mechanical strength when compared to same objects made using traditional techniques. Of course, with 3D printing you can optimise struts and the shape to be better and thus more sturdy, something what you sometimes are simply unable to do with traditional manufacturing. But if you were able to get the same shape with traditional methods, it would be stronger.

@@TheBlobik 3D printing can definitely be used for constructing the molds/plugs. Though it will be a few years (10-15) before we get 3D printing to the point where entire boat hulls can be popped out.

Thanks I wanted to know the price as well

So is tesla going to have charging buoys all over the ocean?

@@wesm3915 probably not suitable for ocean crossing! Yet! :) One way to achieve it (to start with) is a combination of sails with the electric system.

thank you for the price info I totally agree very nice price fuel coast will be worth the money in the future

Magnificent yacht that nobody can afford haha.

I wonder how she would handle rough seas?

Yeah, and I wonder how much all the power requirements of that extra volume play with the solar collection. I suspect it has more issues with range/speed limitations than the 55/60 did. Probably has a larger fuel tank and genset. (and probably mandatory on the 80)

Still looks good, is on the verge of gaining a "double decker" bus style, but manages to maintain.

doesnt take just any cake it takes the whole triple tiered wedding cake xD

Thank you very much Thierry!

Same. 🙏🏼🙏🏼🙏🏼

Only $5 mill haha

@Michael Teeple ignoring cost of lithium ion production. Cruising under solar in my opinion is similar to sailing. Just without the hard work. Diesel electric generators would be perfectly fine. I mean if they are good enough for military submarines I think you can use them on a surface boat.

Spirit 111?

Same here

If you open a business you will,specially a business you can scale.See you in the water.Good luck.

@@marcosoliveira6470 Curious what you do and how it's weathered the pandemic.

Arm floaties for my yachting experience

Every dream started at some point ;)

You can buy an older used one for cheaper and fix it up yourself

O dear they didn't mention it can have a KITE to help it along

@@keithbolger6760 The best ever are foldable trimarans. A Danish Dragonfly 28 with a modified steep gaff rig, that's my goal.

Not that big but maybe wait till you see Metal Shark Catamaran 48 meter Magnet. That thing is a beast with 11.000 nautical miles range at 10 knots.

THANKS SO MUCH RUDI!

Posh British accents awe Americans like myself

My pleasure! It's our first post-lockdown video and was a real joy to film!

Stay tuned for our SILENT 80 to be launched towards the end of this year!

@@silentyachts We are eagerly waiting!!!!

@@silentyachts Will YFS David be doing an update on the silent 80 at the factory in 2022? Thanks 😊

That's exactly what I thought when I started watching the video

Great for cruising around the Med or Africa ... Not so much the British Isles. Also ... they look very slow.

they could use wind power?

@@steveatx8295 Kite

I agree. This should be the standard of all new yachts and as for large ships (cruise ships, container ships) they could be powered by liquid hydrogen. I've seen it on a small scale.

@Andris Falks.... you are wrong on so many levels but I doubt its worth trying to have a dialogue with someone with such a mindset

@@Ski3HigH It's best his doctor has a dialogue with him, just as soon as he stops bouncing off the walls of his padded cell 🤪

@Andris Falks you talk about batteries, yes, the productioni pollutes the environment. Have you thought about, how much fuel and the generation of fuel pollutes the environment? I drove with my Tesla 40.000 km last year, I produced with solar panels all the power myself. For this amount of km a conventional car would have needed about 5.000 liters of fuel. TO produce and to ship this amount of fuel requires about the same amount of fuel. What do you think, what pollutes the environment more - 10.000 liters fuel per year during 10 years =100.000 liters of fuel or some solar panels and some batteries - that last 20+ years and can be to about 90% recycled. Can burnt fuel be recycled?

@Andris Falks "Tell me about" All the answers are here www.tesla.com/impact-report/2019

@Andris Falks Your pollution point has been thoroughly debunked and is just propaganda put out by those with an interest in electric cars failing. The specific study you probably read compared cradle to grave of an EV against gas without considering the pollution of building the gas car. They also assumed the EV would only have a lifespan of 100k miles which is obviously wrong as Tesla's are some of the higher mileage cars on the road. Obliviously on the car side EVs are going to win and pretty much everyone in the industry at this point has come to the same conclusion with all of them building EVs. While electric propulsion does have scaling issues on yachts not matter how much money you have, if you have enough money they can certainly perform very well in the majority of situations. Sure you could do the same for less money in a diesel yacht but part of the luxury you are paying for is not needing generators running at all why on the hook. If you are bouncing around island groups you might not ever need it except for longer passages.

We love your excitement for what we do - thank you! Meanwhile our SILENT 60 has been launched into the water. You can check out the video here: ukposts.info/have/v-deo/jYCkaaWkj6JnpoE.html

It surely is possible! Feel free to check out our channel for more videos!

same, i never knew they had this much space.

Yeah, wonder how much more maintenance this thing takes with unconventional hard to find electric and solar parts? Good thing cats don't take more maintenance then standard boats, oh wait...

@@chrissinclair4442 electric should be easy to maintain. There is no design reason the motors will not be accessible. As for maintenance costs, these are in the mega-yacht league with mega-yacht maintenance pries.

Na, that would be trump 😊

Solar boats have already gone around the world.

@@uni4rm You want to argue this vessel against Solar Planet? Go right ahead.

Great! I´m looking forward to building a wonderful Yacht for you - Michael Köhler, CEO of Silent Yachts

That version looks huge. I'm curious how effectively solar panels can move it.

I think the world touring "energy observer" had vertical wind generators but changed those to retractable wing sails. You could also make (never seen, just had an idea:-) foldable helical wind generator quite easily. Those could be useful in windy cloudy anchor situations or when moving other than upwind..

@Daver G I'm don't take issue with any of your calculations but I do with your conclusion. You simply can't compare HP between a diesel and electric motor and get any understanding of how it will perform. You have to pair each motor up with a prop that matches it's torque. Electric drives are 95% efficient where diesel is only 40% at best considering the torque curve is a lot harder to pair with a prop while an electric motor has a flat torque curve.

I've yet to find a wind solution that isn't noisy. All the vertical solutions have failed in the market. I still think it's possible but more engineering is needed I guess.

@@gregb7353 Daver is a regular on any You Tube post on Silent. It is almost like it was personal.

If I remember correctly the founder of the company said the motors themselves need a replacement bearing after 20,000 operating hours. I haven't heard anything about the batteries but judging by the reliability of something like a Tesla's batteries I'd say they're probably good to go for years. We'll have to wait and see how the reliability of the boat's systems are over time though as that will probably come down to a quality assurance issue rather than parts.

the maintenance is extremely minimal. It is said that 20% of ones time is spent on maintenance when sailing, these are more like 1%. Maybe Washing the decks down?

@@user-dy2qq5wh4b There are probably more systems that need regular maintenance besides the engines. (Watermaker, etc.) And you need to paint the hull below the water line with antifouling. The engine maintenance is just one part of the overall maintenance, but I don't know how big this part is compared to the rest.

@@Scdouglas Hi - I´m Michael, founder of Silent Yachts - it is unbelievable 50.000 hours - at 500 /year it would be 100 years ....

Michael Koehler wow 50,000 hours is wild to think about in relation to that kind of maintenance. Hopefully one day I'll be asking questions as a buyer instead of a very interested observer. Thanks for taking the time to reply, it's cool of you to reply to the community like that and it's something I think more companies should do.

I second your opinion!

What do you think of their shared ownership options?

Not enough area for solar collection i think

@@jamespardue3055 They make solar 55's, which is 16.7m

site says the 60 fotter can travel up to 125 miles on a day of solar charging. Better than I expected. I don't know the range at full charge though

How much money?

@@MrDJE1970 2-3 million $$

I understand that they have equal share ownership plans that allow multiple owners the ability to own, lease or finance by various options. Please check them out.
