Affordable is a subjective term.
AHAA! Finally someone that gets it and saw the quotes that i used.
Like everything in life, its upon the subject to rank/judge anything, according to hes or her standards.
Thanks for watching!
@@CatamaranChannel Engine maintenance, repair and fuel brings the price down overtime. which makes it affordable in a new term.
I assumed "affordable" simply meant it was priced near the same as a wind powered brand new catamaran of similar size and quality. Am I wrong?
@@k11keeper Close, even if a little more.
@@CatamaranChannel Oh I got what you meant by "affordable"...
I’ve been boating for 60 years, had just about every kind of boat and consider this to be a step ahead in comfortable and practical boating. A proper size genset could make up for cloudy days. Like sailing without the inconvenience of sails and motoring without the inconvenience of big diesels! Plenty of room for another couple.
In February this year a Silent 64 crossed the Atlantic Ocean in very very bad weather. On the day after the arrival at West Palm Beach the boat was exhibited at the boatshow - no damages at all. Only 400 gallons of fuel spent for the whole cruise of 5576 nm from Spain to Florida. It could have been less fuel, but the owner was in a hurry and started the generator to increase the speed .... - so - the boat is not restricted to coastal cruising, it is a pure worldwide cruiser.
"only" 400 gallons of diesel, if that is imperial gallons that is 1,800 liters or 1,520 liters for US gallons. That is not electric - that is a hybrid.
see it realisticly - how much would a sailing boat need for this voyage? 40 days cruising and a total of about 80 days on the sea from start to arrival = 5 gallons per day - including cooling heating (it was wintertime in Europe), cooking, tenderfuel ..... and to cruise 5.576 miles? Show me any hybrid of this size that can do this at this speed. A Lagoon of the same size needed 7000 LIter to cross the Atlantic.
A Lagoon sailing would need nowhere near that much fuel and the journey time would / could be faster. You are the ones that are claiming this vessel is solar. It is clearly not electric, it cannot perform without significant fuel burn, therefore it is a hybrid motor vessel.
Sounds like you're deliberately misunderstanding. Diesel burn is for the generator. It does not need to be relied upon but the owner preferred it and it's a good option to have. Otherwise battery power alone could have done the job and that's already a serious achivement on a 17 ton boat.
Noyan Göksu - Not doing it for that reason, the headline being used for this motor cat is "Electric". That is not being entirely honest. To operate it under average conditions, it is clearly a hybrid - that is all.
When I win the lottery, this or the 64 will be mine ...
Until then, I'm just going to enjoy my Kayak
Work hard and or smart.
Thats all it takes.
Thanks for watching!
Rich R. Get yourself a 44 carver
Think big, work smart and within a year you CAN afford this lovely cat!
@Anthony I completely agree. I am saving my whole life to hopefully buy something like a Fountaine Pajot MY40 at retirement. I could never spend $300,000 on a used cat if I haven't paid off my house, saved for retirement, gotten my kid through college first, saved a rainy day fund to help pay for upkeep on the boat, etc. It would feel irresponsible and wreckless.
Everyone seems to be so hung up on this being on this not being pure electric under every circumstance. It is a real release that is designed to do most possibilities relatively well. It can go fast for a day cruiser or cross the Atlantic as a hybrid (faster) or pure electric (slower). That works for me. They also discuss compatibility with a Sky Sail and that strikes me as a perfect match for this boat. You can gain some speed and efficiency without blocking the solar panels. This is early tech. It will only get better from here. Think about better batteries coupled with more efficient solar panels covering a larger percentage of the boat. Imagine what 2-3 engineering cycles will look like as real world experience can now come in!
pure electric across atlantic,,,60kwh theoretical max.in north atlantic at narrow crossing point maybe 35kwh? 3.5 gallons of diesel a day equivalent. good luck with that
solar panels will never power a boats propulsion system.
they could be 100% efficient vs current 25% and the boat would still only get 40kw or 54hp for 5ish hours a day
thats the theoretical max if you sucked in 100% of the suns energy on the boats surface
I hear the hull in the next gen will be built from pure unobtanium.
Let me correct you there, because im sure you made a typo.
Unobtanium is a cryptocurrency.
What you mean is unobtainium.
Thanks for watching!
The only thing that can be pure electric is a calculator.
An absolutely spectacular vessel. Love love love this!!!
as is it has 10kw? 15x400 and smaller 12x250 panels? maybe 9.5 while website says 9kw
even if you went crazy moving the saloon far back, adding another row of the larger 400 watt panels in front for 5x5 on the roof
making another 2 deploying structings in the front giving 5x5 on the bottom and 2 deploying 2x5 arrays for a total of
45x400 watt panels and 12 250 watt panels you would still only have 21kw of power
----------------
you'd get 28hp equivalent theoretical power for 6ish hours a day?
10kwh is crudely equivalent to a gallon of diesel so as is 6 gallons of fuel saved a day
if they went crazy on the boat you'd perhaps save 12 gallons of fuel a day
realistically the solar panels would need 3+ days at anchor to charge the ships 140kwh of batteries
makes perfect sense as a live aboard, can run the AC indefinitely 60kwh a day, slowly charge your boat and island hop
but theres a huge difference between powering AC/cooking/electronics and the ships motors using solar panels
after all you could just sail over to the nearest island every 3 days, plug in and charge to full in a day for 30$
really dont get why if you wanted to be green/not use motors you wouldnt go with a sailing catamaran with a large flat roof without any skylights similar to what we have here
other than 4/5 thin cables and the mainsail blocking part of the array while sailing it would be largely the same
panels in the back of the boat would be mostly unaffected
solar panels will never provide the power a sail can on a decently windy day
on the other hand they are really not that expensive. a 10kw array should not cost that much
the 140kwh battery is only equivalent to 10 powerwalls at 5.5k a pop for 55k, meaning the solar electronics are only worth some 90-120k on this boat while its price tag runs at 2M vs lagoon/leopard with sailing rigs and diesel motors in the .8M-1.4M price range. 50/58 ft boats
have to say though, if the cost can come down as it has no sail, electric motors that aren't that expensive vs diesels
and the roof structure is largely a flat slab to a price point similar to a lagoon or leopard it could be the tesla of the waves
really don't see why it would be that hard to take say a newer leopard 50 with flat roof, get 7-9kwk of solar on it and add diesel/electric hybrid drivetrain for very little extra cost along with 100kwh storage for some 70k
Finally someone who get's it. This concept doesn't make sense at all. The solar peak power relative to the boat's size displacement weight makes it horribly underpowered. But I think the main problem is the combination of solar and heavy luxury items. This boat is really only made for the marina. Any cruising will quickly require generator power = diesel.
On the other hand I don't believe that being underpowered is in general a necessity for solar boats. It's a matter of choices and priorities. For example, let's take a 6*11 meter catamaran (or trimaran) with solar panels over the entire(!) roof, which should be >10 kW peak, LiFePO4 batteries, light weight foam core construction and a total displacement of ~4 tons (yes, that's totally possible!), narrow beam wave piercing hulls (a bit more like Wharram design instead of those big fat liveaboard hulls)...
SAILING CATAMARANS ALSO USE FUEL FYI....
Plan accordingly, and you can enjoy a QUIET cruise....
QUEIT is the attraction for me personally....
Remove the Motors and Generators ... Sail only :D
Perfect for the charter market, especially in the tropical and subtropical areas. Charter yachts rarely travel over 50 miles per day and majority stay within 2-3 hours sail from thier previous anchorage.
I really hope that with time the range and efficiencies will improve. I think this is just a very optimised diesel-electric yacht that uses solar as its primary energy source and diesel as its ultra long range energy reserve. I like what I see. I would add 2 wind turbines just for a little oomph on windy cloudy days on an anchor. Can't wait to see how this tech pans out. I personally would still use sail as I grew up on this and would like to explore very very isolated places in higher latitudes.
To all of you that cruise at 6 knots on a boat over 55 ft you should really reconsider your hulls and optimise. I think we cruised at 6 knots on a 35 footer, usually, at 55ft you should reach about 8-10kts on a monohull and in theory more on a cat. On Fast cruisers usually even faster. Now with this incredible piece of tech, the 6kt-8kt just from solar is very very impressive.
You should check out the 75 foot version when it's out that's by far my favorite Catamaran not too big not too small, stable, doesn't consume too much fuel and no crew required.
Its going to be 79 foot, its being build as we speak.
I will be there when it hits the water.
Thanks for watching!
Jeff from New York proud owner of a 4670K I can’t wait to see that!!
Neither can i.
Stay tuned!
Catamaran Channel did it hit the water yet?
Such a stunning yacht, all the right things in all the right places. Silent by name silent by nature, I especially love the master cabin.
The helm inside the salon space! Glad someone is thinking realistically!
I really like this company!
UNconventional Me
Agreed 100%
Thanks for the walk through. It would be nice to see people documenting their experience out at sea with this boat. It's the future.
I love the concept and that they demonstrate it can actually work. Slow cruising with solar alone.
Of course a much smaller vessel would be more interesting, less power and batteries needed. But it's hard to get enough solar panels on a smaller catamaran.
It's also interesting that they used flexible lightweight solar panels on the flybridge roof and glass panels everywhere else. The flybridge design is really cool.
I could not even afford one of them models.. which are real kewl. Are they R/C? When the 79 is done I hope you can show us. For the money in the long run this is what you need. The fuel savings. The minimal maintenance. (compared to a power the same size) No ropes or sail, unless you do the Sky-Sail but that is automated mostly. You can have sails too if that is what you want. Hopefully by the time the batteries start to go the price on them will go down. 28 would be a big chunk o change. The great part is they can build it to suit you. There is even a spa option on the larger version. If they used the ferry version and got some nets.. they could clean up the plastic problem for 2/3 the cost of fueled vessels. Maybe less.
maintenance will be amazing/non existent possible entirely outside of the water pumps touching saltwater
i agree sail+7kw+ of solar is an interesting combination!
I was on a nuclear submarine for six years, you'd think that the most dangerous thing on that boat would be the reactor but you'd be wrong, it was the danger of battery fire/explosion. What safety systems are in place on this vessel? 🇺🇸
that and a motor or motor controller fire, i have seen many let out the smoke while working in industry
I always wondered about that
The most dangerous things in the submarine where the weapons and the soldiers holding them
Hi can i have your email?? I have one important question
I could care less about this boat, but thank you for your service!
I wasn’t going to buy one of these guys until I saw that there were cup holders on the fly bridge. Now I’m sold !!
This is the future of cruising! Thanks for posting. I was looking for a good video of this yacht.
So pretty! the rooms look spacious and bright!
WOW The future is here and it's silent, very cool.
I think there might be a way to get more speed out of a solar or passive powered catamaran, by applying or merging other systems. But this is a good starting concept.
Stunning yacht! Low cost to operate is the way to go.
Plus a small antenna mast for sailing and voltaic sails, no more heavy fuel just a small mast prop at night... just thanks to all the guys who made this dream machine into das boat... Thumps up !!!
If you live in the Bay Area,a house costs a minimum of twice this,and has to stay in the same spot year round.
This could convince me to get back into boating. One of the reasons I got out of boating was that I was sick of being gouged by the boat yards for services and maintenance, with electric I should imaging that would remove 80% of the annual maintenance over ICE boats.
I´d just like to shout out to the sound designer..
beautiful soundtrack..I´ve saved this video to listen to it during my ablutions haha
Go to see that you finally picked up on those ablutions.
ITS ABOUT TIME!!
I'm 64 years old. They told me when I was a kid that someday everybody would be using flying cars. No flying cars yet, but this is pretty close.
Yes.. its neither a car nor is it flying.. i get what you mean ;)
Flying cars have been built, driven & flown. They're just not practical. There's always a compromise, so they don't make good cars or planes. Also, if everyone had one, they'd make current road casualties look like nothing. I realise you weren't being entirely serious, but I too shared the same dream, then I talked to some aero engineers & they laughed at me.
I dunno why but I could see myself just living on a boat like that.. Even if only mooring.
This is one badass boat. She is sexy gorgeous and very beautiful. I would be proud to own a boat like this. Both bedrooms were breathtaking and beautiful. The salon and kitchen area were wonderful. And the helmsman area was wonderfully apointed as well. But the cockpit was the real charmer. It was very spacious and beatuiful. Tons of room i could host a 10 person party out there serving beautiful bloody maries, and filthy dirty martinis, along with wonderful snaks as well. This cat was a wonderful luxury boat by far. Hats off to the builder!!! Good job chum!!!!
Thanks Joseph, thank you so much!
Thanks so much for doing one of the Solar Silent Yacht models for us. I've been so curious about this yacht manufacturer and their layout and amenities, but couldn't ever get more information. What fantastic and beautiful ship. I wonder what configuration, engine-wise, was that last shot of the video cruising as it appeared to be going well over 10 kts. Don't believe I saw the Starboard side hull in the video either smallsmalliver and I was curious about the sleeping arrangement there as well.
please go to www.silent-yachts.com or write me an email - you find it on the website
This boat is beautiful and massively roomy except it fails to have the one thing that matters most to me and is a deal breaker. That is a Salon Living Area with an opposing chair/seat. The massive table in the salon is ridiculous. Also they could do with some rounded corners on the countertops in the kitchen and salon area. I really do like so much about this yacht that they they got right and I hope it does well.
Lucky its all custom. You can add or remove anything you like.
Thanks for watching!
If I win the lottery I will be coming to see you guys, amazing boats.
When someone creates solar sail cloth this technology will sky rocket!!
mrabrasive51 I would buy solar sails in a heartbeat and put them on a Tesla for infinite driving
Some has. French sailmaker Alain Janet is the founder of Solar Cloth System which has been busy developing a practical system for generating electrical power from thin photovoltaic films laminated onto modern sail fabrics…
Let’s Talk good to know I will try to buy those for the sailboat I will be able to afford to live on one of these days
Solar needs to be 90 degrees to the sun
As a concept it's quite nice but in practice I'm guessing it has varous shortcomings (see various arguments in comments below). Personally I'd take the concept much further and add the following:
Kite: wind power offering reduced shading of solar cells vs conventional sail rigging.
Wind and impeller seondary and tertiary battery charging options.
Foils: higher speed for less power output and greater energy efficency.
Now you have something which is a zero emmisions, silent, renewable energy, bluewater, fast cruiser with a shallow draft, low height and max clearance.
I'd buy that for a dollar... shy of a milion dollars.
AdeboFunkyVoodoo this one is already 1.3, so with all the addons you want it will be closer to 1.8
Beautiful and well designed.
With 140Kwh battery power and 125Kw motors, a full speed drive would last roughly 60minutes with general electrics onboard.
The 10Kw solar panels would need a minimum of 14h direct sunlight to charge fully ( 2 days ).
It is interesting to see yachts catching up on the new E-trend.
Lightweight material options will ensure lower prices or increased performance ( batteries are expensive ), more power is necessary to increase flexibility.
Diesel hybrid would be a nice solution offering security to stay moving, at the same time charging and providing heating when needed.
everyone will use it with 30x2 motors. and yes even with them i would recomand200 kw+ bank
Pretty sure the batteries are 500KWh each not 5kWH. Totaling 1.5GWh in capacity. The really cool thing is that you don't need a starting battery!
Beautiful catamaran !!! Good to see this . Awesome .
I am in love , but could not even afford the dingy , so I will keep buying lottery tickets and praying, LOL
You and me both, man. I'd love to be able to afford this thing, and just spend the rest of my life cruising.
Dreams without goals are just dreams.
Thanks for watching!

Hey, I'm building one of those 1:10 scale.
First I know of an E-Cat was from a swiss guy that move to thailand about 2yrs back doing custom E-Cat for clients, then Sunreef released theirs 1st quarter of this year with their 67ft version at euro2million plus & now this. This is fantastic! & definitely the way to go.
that could have been me - we retrofitted a Wharram cat in Thailand - still cruising around the world - but it was at least 4 years ago.
@@michaelkoehler5845 Hey! It is u! Sorry if I got the years wrong. Lol! Still going, that's great! Me can only watch for now. But I am aiming for a zero emission cat like urs in the near future.
Michael Koehler u should check out this guy gerrad morin or something, he created a hyperdrive(Motor) that only uses a miniscule of amperage via rf frequency that...it can be use in any electric vehicles or boat or whatever u want it to, according to him. A tad to tedious to explain here. He has a youtube channel if u want to check him out.
Hi Noor - thanks for the advise, I´ll check it!
@Brian Foote stop assuming u know everything. & Stop trying to make arguments when u don't like something u don't understand.
Can you post the stats on the 250 kw motor please
Wonder what the sun glare is like when using the upper deck to navigate when heading into the sun?
I love this boat, but if I'm not so bad in math, with two 250KW motors and fully charged batteries of 140KWH (what may take two days of charging) the boat can run only 28min at full throttle. Right?
I get 16.8 minutes (0.28 Hours). And at 10KW of charging, you need 14 hours of daylight to replenish the batteries. So, that's like about 6 nautical miles per day of sunshine at full throttle. I think you generally want to avoid full throttle on these.
Multiply 0.28X60 = 16.8 = 16min. 48sec. That's it. But it is not very likely to obtain 500kW even as peak power from 140kWh battery.
@@milesjackson2178 Correct, 0.28Hr.
@@sergeykorn Sooo, after all I think the only thing we can conclude is that you actually "are so bad in math".
Regarding the power it will probably help every battery's life span when it isn't emptied in under an hour. And regarding the range the same things that applied to real diesel passagemakers still applies: To go REALLY far, speeds around 6 knots are optimal (disregarding special conditions like currents) and going solar only those energy-minimizing speeds are suitable for continuous operation. That will never really change, regardless of battery capacity and also regardless of solar panel efficiency, as long as they do not reach 100% which is completely unrealistic.
Rainer Zufall Do you even know what math is? I don't see any math at all in your "scientific" blah-blah about how to be frugal to save limited resources. "... regardless of battery capacity and also regardless of solar panel efficiency...." do you even understand what you're saying, smart guy?! :)))
why was there wires not connected in the battery compartment? 7;57 mark pause and there are a few....
WOW all the haters on here. Guys, this is fantastic innovation and a beautiful product. In a few years (~10) I hope that these will be commonplace, and just about the right time I'm ready for early retirement! Keep out the great work, and don't pay attention to all those socialists asking for handouts and complaining about affordability. Those of us that are dedicated to enriching our lives through education, dedication and good old fashioned hard work, will be your future clients.

I think thats because the have been around for quite a long time and proven themselfs over and over and over again, to be very practical and trustworthy.
Thanks for watching!
I just seen this ... Some of those whining about price / go look at a 55 Cat that sails ,,,Trick the sailboat to be a live aboard and the price competitive / Rigging and sail replacement VS battery replacement ,,, that needs researched , The square edges on all built in cabinets , 1 sink galley , hmmm not so much Full re-fridge ,,,NICE ...... Running around Philippines , US's inter-coastal high way , VI and Bahamas she seems almost perfect
tesla model s has 100kwh. may shoud be upgradable up to 1000kwh in the yatch? also there should be other extendable solar charge panel to make this yatch usable.
Actually the 2x 135kw motors are probably more than enough to get to hull speed, going any faster is just using lots more power to go a tiny bit faster.
I Love catamarãs 😍😍😍

If only they had invented some type of water craft years ago that harnessed replenishable energy........perhaps some type of canvas that harnessed the winds energy??
Yes, like wind sails or something. Now imagine that boat, let's call it a "sail boat", sitting at anchor (were it will spend most of it's time) with almost no power and running a generator for hours a day to power refrigeration, hot water, electronics, pumps, etc. Also imagine sweating your ass off because there isn't enough power to run AC without running a generator almost 24x7. Man, that is the future.
@@CL-gq3no No ones saying dont have solar or wind or a water turbine. Running electric engines instead of wind for and ocean going yacht, is just silly.
@@GerardIrvine, I disagree. For "cruisers" it makes a ton of sense. little to no maintenance for electric motors. Only one lightly used diesel engine to maintain (the generator) instead of three (genset x 1 + propulsion x 2).
Ability to run off of direct solar or batteries for either long durations at low speed (24x7 at ~4 knots) or shorter durations at higher speed (several hours at ~7 knots). Diesel as backup when conditions require both distance and speed. Otherwise you could hop from place to place for months without using any fuel at all. Basically similar pros/cons to a sail boat, but with some significant advantages at anchor and no need to manage/maintain sails and rigging.
When at anchor (most of time for cruisers) you have a giant solar array and house battery bank to power everything. No need for other fuels such as propane/butane for cooking since there is more than enough solar/battery power for electric cooking appliances. No need to run a genset for hours a day when AC, water makers, etc. are needed. My 2000 sqft Florida pool home uses less energy in the middle of summer than that boat can produce and store on a cloudy day so there would be no concerns about energy on those boats when at anchor.
Now, if we are talking about people that want to get from Miami to the Bahamas and back over the weekend and don't care about the cost of hundreds of gallons of fuel, then this is not the boat for them. And I agree that sailboats are great, but I don't see this as a bad option at all. It is similar in many ways to sailboats, but with different ways of accomplishing similar goals. For some cruisers this approach may be a better fit.
@@CL-gq3no add that this could be a one man show with close to very little boat experience vs a similar sized sail boat.
Who are you mostly likely to hear in action, the affordable e-catamaran or an affordable screamer?
Finally a complete solution. I hate diesel/petrol fuel. It stinks, it's expensive and when you run out then what. With the sun your journey is endless.
If this were diesel generator, solar and wind then I could get behind your statement. With several days of cloud cover mixed with night time you'd run out of power. I understand that ultra violet light still gets through clouds and you'd have a little power generation but not much with the size of the array they have fitted. You would need to go into conservation mode, so not to drain what little power you have.
Lol...sorry at the time I made this comment. I was unaware that it's toting a diesel generator backup to drive the motors. Very disappointing. I'm sure it will one day be all electric. Still it's a beautiful boat and worth looking into.
It can be all electric.
Its the buyer that decides.
Thanks for watching!
@@CatamaranChannel True. One can decide to sail it according to the amount of charge they are getting from solar panels, and can go without using any fuel.
It is a clever design, but probably its real value is in lower running costs. Not just fuel used, but maintenance costs. You still have to maintain and fuel a generator, but you aren't also feeding and maintaining one or two big diesel engines on top of that. And for people saying get a sailboat, this also drops all the costs of maintaining sails, lines, standing rigging, etc. No boat is maintenance free, but this one is going to require a lot less intensive care and feeding.
Trye, Maintaining a generator is way easier than maintaining an engine used for propulsion. Generators are much simpler machines. For peace of mind, one could get an additional, smaller genset installed as backup.
I'm in bus station using public WiFi.
I can't even afford watching the clip! I guess this is life. Watch what you can't afford and when you afford it, find something else. 🙄
yeah dude get out of the city
I know someone, who bought a small steel sailboat for £3500 and spent another £2000 on it. He has already sailed med, caribbean and back in UK now.
what they don't tell you is your cruising range on batteries, how long it really takes to fully recharge drained batteries with the solar, the 9Kw is only going to be around noon on a very sunny day, and how much you will have to use the fossil fuel generator on a long cruise, solar is great for living at port but try to run it a few thousand miles
I started thinking, "What kind of insane idiot would put the engine directly underneath the bed?" Then I remembered it was an electric motor...
@xwriter100 That's probably not the spot I would choose for my afternoon nap. ;)
Its silent soooooo!
Great for those with more money than brains...reading previous comments people don't seem to understand that the solar panel array will produce at best 40kwh a day average which will run the 2x22kw motors for less than an hour at 8 knots max and they don't even mention the size of the battery bank but they claim 100nm autonomy which would have to be over 500kwh which would take 2 weeks to charge up by panels. Either you are cruising at sailboat speeds of 6 to 8 knots for 12 hours before draining battery bank or maybe 1-1/2 hours at 12-20 knots (2x135kw) Then your running on gen or back to dock to charge the batteries. Which is great if you just want to spend the day on the boat and back to port, but don't kid yourselves into believing that this boat is a viable ocean crossing vessel. BTW 500kwh battery bank would weigh roughly 5000kg which is highly improbable in which case autonomy is greatly less than advertised.
What is the range on this model?
For instance if you wanted to cross the atlantic or pacific ocean and if there were a few days of bad weather...
Does the solar capacity on a sunny day eclipse the cruising speed power consumption?
In case of bad weather you simply run the gen for a 2-3 hours per day
Brian Foote yes, the motors could drain the batteries in less than a half hour at 20 knots. But the power needed to drive the boat is an exponent of your desired speed. At 6-7 knots it would take 20 hours to drain the batteries. So the boat has unlimited range as long as you’re cruising at 6 knots.
Looks like there are generators to produce electric energy! 400 galllons are still a lot in Liters = 1512! Okay its not too much or crossing the Atlantic but its a lot just to produce Electricity! That means you need Diesel!!!
I’ll buy it! Don’t mind to live on ocean. Can go anywhere. Don’t mind the lockdown. Whoo!
Great concept, but I find it butt ugly. Looks like something IKEA would build. Lots of sharp corners that could be dangerous in heavy seas. 10,000 watts is about 13 HP... Would be reluctant to venture out in hurricane season. Solar boats keep improving, that’s for sure, but I will hold on to my power cat for awhile. I like my twin Yanmar 440’s...
Wish the top deck had more floor space, and the solar panels moved on top of a larger over hang. You could have an epic party deck on the fly bridge!
I would add two wind turbines just for that extra power. Could this be used for off shore sailing long distances? If it's only for coastal sailing then it's not very useful.
Wind turbines would not work for obvious reasons.

Why is that so obvious?

Shading
A couple of small VAWT's all the way in the bows would work to supplement the solar and they shouldn't shade the solar panels to any real extent.
The forward view from inside is terrible. I think the layout for long term cruising could be much better on a boat this size.
Why wait for wind when you have the sun!
Ian Hughes in Norway we have 20 hours of sun during the summer, he could charge 100KW - 150KW of sun every day. I sail, and make 6 knots on a good day - 20 hours for a 120 nm stretch. They can do the same during the night. But I have a constraint on equipment at 15m / 10 tonnes.
Ian Hughes - Not much sun at night, or at high latitudes in the winter.
Theres a common thing boaters do, they follow the sun.
Thanks for watching!
@@poruatokin This boat will do 6 knots endlessly with 12hrs sun/day - there's batteries for nighttime. I wouldn't cruise in winter anyways. Sails or emotor.
And no sails or rigging to maintain, no tacking or reefing, no extra crew required. This is the future.
Ian Hughes - There are many problems with your statement.
1) The sun does not shine directly downward for 12 hours. PV peak efficiency is limited to 2-3 hours centered around local noon. It tails off dramatically in the morning and late afternoon and with latitude.
2) Not every day is brilliant sunshine, even / especially in the tropics. A few squalls or hours of cloud will seriously put a dent in power generation, then you are back to burning diesel.
3) Looking at the figures being discussed, running propulsion on battery through the night is not possible, they are required to run the generator on a routine basis.
4) Sounds like a very boring future then. Might as well live in a house and have a wall sized TV that shows scenery going by.
5) Did I mention it is Fugly.
6) Related to 5) above, possibly because they are trying to make flat areas to mount the panels, the whole design is horribly boxy with a huge amount of windage that will seriously affect performance in many conditions.
It’s beautiful. sight lines look a little challenging, but not to bad
someone should make solar powered cargo ships too.
half the max weight of the vessel will be the weight of batteries, and half solar panels. There won't be any scope of loading any cargo.
Beautiful boat, not sure about the *affordable* comparison just yet. But I get the point for what you get.
its Affordable! i'll take 3. its only 1.5million dollars. saaaweeeet
that 1.4 million "pounds".
more like 2.3 million U.S. dollars.
its euro.
Thanks for watching!
@Gordon mather --- I LIKE THE WAY YOU THINK... AT THAT PRICE, WHY BUY JUST ONE......
the prices run from 2 to 3 million from what I have seen on the net. which for a new batch isn't bad for the size
Did you watch the end of the video?
The 'wave' of the future, today !
Somehow i feel its a missed opportunity to not have sails at all? I would like to know why something like a wing-sail and/or a spinnaker/parasail wouldnt be an option? A wing sail would provide the added advantage of presenting more surface to place solar panels as well. Anyhow, i think its a missed opportunity.
czcams.com/video/QcgGht4eX-8/video.html
@@CatamaranChannel Not the correct mix as well. Such a big boat and it only has 5kw solar generation (max i assume!) so more like 2-3kw on average. Which is WAY too little. I know we are talking luxury crafts here and in this case its kinda just a "hype" item to pride around about for these type of users. But as a consumer wishing for less luxury and actual solar cruising along with sailing, this aint it. Its a half way compromise like this. I guess I am waiting for something that isnt out yet.
Smiling...I want the SW64!!!
I have to agree with you on that one.
This one is very different.
Thanks for watching!
Awesome if they keep thinking further maybe they'll be able to make a boat move on an other renewable energy. (I don't know maybe something like the wind?)
Wind? That's just crazy talk :)
By far one of the coolest boats on the market. Now if they would just get rid of the gas engine on the tender.
Theres an option for that to, electric outboard motors are already for sale.
Thanks for watching!
my idea would be some of those foldable solar panels on the roof of the dingy .. keep batteries charged. They need to invent light weight batteries..
A lot of people comment about the word "affordable" and I agree is a subjective term that in it self shouldn't be used for marketing. The market these people are selling this boat to already more or less know the price so they don't need to be told is affordable, they already know they can buy it. So the word affordable should not be used in marketing , so that way people who can't afford it keep commenting the same thing.
'The market these people are selling this boat to already more or less know the price so they don't need to be told is affordable' No they dont. This one is the cheapest untill now, wich makes it affordable for them. the one before this one was allot more expensive. ( i think double this price but not sure, its on my channel to)
Thanks for watching!
1.4 Million Euros. Great! Let me check my bank account....
Catamaran channel, I liked this video because you asked me to at the beginning of the video. Why is there no sound for the first forty seconds? I'm glad you put the price in there, it is a goal to work towards. It's a beautiful boat, I think I can own one in ten years. I love the idea of sailing with all the solar panels.
It should be background noises, but it might be to soft.
Oh dear... Lets do some math?
10Kw of solar (although the specs at the end say 9) with the average 4 sun hours = ~40kWh of power generated per day.
40kWh / 24 hours = 1600W continuous available.
1.6kW motor (2hp) pushing a 17ton boat... Suuuuuuure!
But it gets worse... That 1600W also has to handle the house loads (cooking, refrigeration, AC, etc)
This thing -may- be able to sit at anchor without a generator , provided its sunny and you don't need to much AC to stay comfortable.
Any claim that it has "unlimited range" or can travel at >4Kts on solar alone is outright lies.
The manufacturer should be ashamed.
Where did you come up with the 1.6kwh motor?
By the way the motors dont run on the panels, they run on the batteries.
Thanks for watching!
So.. if the panels dont run the motors... where does the power for the motors come from? Burning diesel! But in a terribly inefficient process because you're turning diesel into mechanical energy, then into electricity (generator/alternator) , then transferring it to an electric motor , then back into mechanical energy. This thing will burn significantly more fuel than a direct drive diesel.
Theres been allot of testing done on this concept.
Did you read the pinned comment up top?
The comment regarding the Altantic crossing? Yes.. Samuel (owner) initially wanted to cross without burning any diesel, however he soon realised this wasn't possible and had to fire up the generator. This is exactly my point... All of the specifications mentioned (range, speed, consumption) are possible, but not together. ie. I'm sure it can do 20knts (for less than 30minutes) , or it can travel indefinitely (at less than 2knts, with no current) but the marketing material has potential buyers believing they'll be crossing oceans at 6-8knts or better. It's simply not possible.
I admire the goal silent yachts have of reducing emissions but the reality is this thing will burn MORE fuel than a standard diesel cat due to the inefficient propulsion system.
Ok.
Do you know the owner?
And how long do you think it can run at 6-8 ,knots?
If i was given a Silent 55 I would pilot it anywhere and everywhere.
There are a few hints that the designer of this craft chooses form over function too often.
I can't imagine servicing the generator in anything but a dead calm. I didn't see inside the port aft compartment, but I am forced to assume a redundant gen set exists there due to this being an electric vessel.
The sharp corners everywhere in the interior are giving me bruises just watching this video. These countertops in the galley may never harm a soul in your kitchen, but there they dont pitch, roll, or heave. Forget about letting children on board whos heads are at this level.
I hope that this platform was designed to showcase the technology packed inside it, by adults, tied to a pier because the packaging is not sea worthy.
How well can this handle cold weather and storm?
It has been specifically designed to perform poorly in cold weather and storms.
Not fond of the IKEA interior.
Hopefully prices will go down over time. Not convinced by the choice to reduce visibility from the dining area and increase it in the master bedroom. It is not coherent with the functions of each space.
Unlimited cruising range my ass. How many miles at 12 knots without sun or charging?
Just like sailing vessels. No wind no cruising...
@@mbirra not true if you run out of juice you have to wait to recharge even if the sun is out. Remember you still have heating,watermarker,fridge etc Wind is instantaneous. we all know battery has a range they should publish. If you had to choose between solar or wind for trans Atlantic which would you choose? Which is the safer choice? No gas. wing cats are the future
135KW motors with 140KWH of storage so 13.8 miles in 1 hour at 12 knots. then you kick in the diesel genny and it becomes a diesel trawler.
sailboat: no wind no cruising. Solarboat: no sun - still cruising on the battery - for hours. And - how often per month does the average sailor cross the Atlantic ocean??? For 99% of the typical holiday cruising a Silent Solar Yacht is the much better solution. And even for transocean it is not superior, but comparable to a sailing cat of similar size and comfort.
135KW motors with 140KWH of storage so 13.8 miles in 1 hour at 12 knots... blabla NO, you dont know much about electrics do you :), they intentionally use overdimensional electric motors as watt usage increase exponentionally, wich means they lock them maybe at 50-60% at max usage, that will decrease power usage maybe 65% or more, its not like running half speed will use 50% power, it will use far lower then 50%.
Stunning, beautiful, a lifetime investment in luxury, safety, and world cruising family fun!
affordable to who???? the 1% ...talk abut click bait
Dumbass, you thought you can use your food stamps to buy this cat?
Let me explain, people who arent in the market for these kinda boats get confused, i understand that.
If your in the market for a 55 foot catamaran, this one is affordable and it might even be your best buy.
I hope that explains it for you.
Thanks for watching!
i have a 2007 36ft catalina ...what is food stamps you talk about?
@@johnathanray8977 Do you think 36 foot boats tend to be the same price as 55 footers? Do you know what 55 foot cats usually cost? Obviously the poster meant it was affordable compared to similar boats, not compared to your bathtub.
what are you talking about... closest you ever been on a boat was on a vidio game
Cool boat!
By far it is still the best yacht on the water
Probably a dumb question..... but what are the potential consequences of a major lightning strike?
At last a nicely arranged catamaran !!
well if you think what it can do and what it really is it is affordable. it's a floatable house ready to go. it can even make water from saltwater ffs. i wonder though if you were to compare it with an equal size apartment or house which one would be cheaper? i mean like insurance and annual payments and stuff.
would have been nice if you shut that music down and gave an opportunity to listen to the conversations and specs. which are recored in very low voice. Also does it have a kite sail option?
Why oh Why does this not have a split sink (2 sinks ). That is a flaw. Also why the raised bathroom sinks - they are so difficult to use efficiently. Other than that ..It is absolutely breathtaking. I LOVE it.
Stunning, the future is now.
its a nice concept.... but i dont see taking this baby out to cross oceans on it its too nice to have it destroyed by a storm wave ..the only way i see world travel is Viking style..meaning staying close to the coastlines of continents as you travel ....whats the msrp on this btw ?
about $1.5 million USD / $1.4 million euro. Also, the silent 64 already did a cross Atlantic from Spain to Florida in bad weather with no damage.
