I’m docked 100 yards from this boat. It’s beautiful. A crew member is hosing off the solar panels. My 40’ cat uses no diesel either, as long as the wind blows in the right direction.
FYI I lost my drone in the ocean during the making of this film. RIP Drone ☹️ Approximate location, water depth 14 feet. Welcome to try and find it: Near Biscayne Bay, Florida goo.gl/maps/uRpvzkpz63hTDZPr8 DJI Mavic Pro
You re 1443234566 number in line, who lost their drone in ocean. Wtf. Do you realyze that not so much pictures of drone from oceans. "drone want to break free" :)))
Don't understand people's idea of it's too slow. The point is to be out in the ocean and enjoy the peace. When you finally get to an island or something you can enjoy yourself there.
@@liuwei3102 Dude multiple solar boats have gone across the ocean. Its a boat as long as it doesn't sink it can handle storms and stuff. Otherwise what would sail boats do during a storm when they can't move themselves away.
It is too slow. You need the speed for bad weather. When the clouds are coming I wanna get straight outta there and not cruise with 3 knots in the storm! What's the point of having a solar yacht when you can get a sail yacht cheaper, faster ,more reliable and on top of it more economic
@@kek207 What is the windspeed at which you have to pull in the sail's, just curies. Looks like sailing with the sun for me, more sun more speed and no moving parts but the shaft and propeller
The hell do you mean young enough, there's no deadline put on fulfilling your dreams. I have planned out my life to get a similar yacht and modify it to sail by myself and travel around the world, it's going to take me 15+ years from the point where i am right now. You can find a way to do stuff if you commit yourself to it.
I do like this setup for non sailors. Those who don't want to learn how to run a sail rig. The speed isn't an issue at all as most large mono hulls run at similar ranges. This would be a great boat for someone who wants to cruise the Caribbean but dosen't want to do around the world cruising. Great vid!
I can definitely see the value of totally silent propulsion, although I don't think fuel cost is big at displacement speeds. I only fill my sailboat's diesel tank every two years. The part I can see as a plus is the total silence. Most people agree the best time on a sailboat is when the sails are pulling and the engine is shut off. Beautiful silence.
i grew up sailing with my dad, and you hit it on the head. the minute when the boat settles in . gets happy and picks up a little heel, its just magic.
Maybe the sail version is the best option even if the guy says it is the worst. You could charge the batteries with shore power and use the electric motors only around the mooring or when the wind drops, otherwise use the sails predominantly. The panels can power the creature comforts. Just a sail boat really but with lower maintenance motors.
To translate what he said about how much torque each motor produces: 3700ft/lbs EACH! And it fits in a tiny storage compartment!!! This is incredible and is the future! The one place where battery weight is really not a problem is a yacht or large ship like this!
@@EternallyGod Who says they wont. Lets put it this way, the Graphene batteries should be smaller, lighter and take more charge. Even if they're just smaller and lighter it has to be an improvement.
@@EternallyGod Why are you so aggressive? It's OK to have solar panels but without the battery to hold the energy created there's no point. The two work together, in my uneducated opinion. So get off your high horse. You sound like a right belter, and I would suspect you don't have many friends with your attitude. You, my angry friend, are lacking common sense and should learn how to speak to people.
Did you see the same video as me? Where did you see "no fuel anymore"? This boat can go 6 knots for 60 minutes under its own power under absolutely ideal conditions with full battery. And had no sails. What do you think happens after that? The zillionaire on-board waits two days to recharge to go another 7 miles? No. They burn diesel the rest of the way like everyone else. These solar panels come at the cost of sails. That is a grave cost.
I looked at the Silent Yachts website and at least on the 50 footer they use a pod-drive setup. Something they _DON'T_ list for any of their models is the "air-draft" or bridge clearance. If it's under 15 feet this would be _THE_ perfect "Looper" boat. The power configuration that _I_ would want is: 2x 50kW motors, 300kWh (or larger) battery bank and 150kWh genset.
This is interesting tech for a couple reasons: 1) Pretty soon we'll have batteries that hold twice the capacity. 2) Lighter weight composites using graphene might make it possible to put this boat on hydroplanes. Then you do your Bahamas trip at 25 knots instead of 6 knots.
@@stevenf927 If it can do 17knotts thats a lot faster than some so called performance yatchs and you could make it go faster just by sacrefising space in the hulls or extending the hull water line .... and stripping out all wt Like racing boats.. but i sure as hell wouldnt want to live for weeks or months on one. This is your holliday or full time off grid home and window on the world. EV motors just trash ICE motors In so many ways thats why the first vehicle to reach a 100kph 60mph was electric.. they can run in reverse and even run regen and an average bloke can man handle one in and out a boat try doing that with a 250-600 hp equivalent diesel engine. If you want fast, look at the foiling electric launches which use 2/3 less power when foiling than a displacement hull. 🤷♂️ If you want a race sail boat there are already Katanas etc being built with hybrid and limited electric systems.. Telescopic rigid wing sails are probably more efficient than trad, sails and given some materials advances a lot less hassel.
@@KentSpain85 Silent yachts like this have about the same kind of maintenance as a regular house, except, you don't have to pay for the electric bill, so... technically, it's better than a house. :P
if a yacht is better than a house then why dont you see the average person buying yachts instead of houses? the target demographic for yachts are millionaires. they're a luxury
Been watching videos about boats for a while now and this is the closest to what I'm looking for. In 10 years I still won't be able to afford this one, but it gives me hope that my perfect boat may some day become a reality
Roy Moon I an other vid, Silent Yachts said that with maximum speed of 4 knots, you can sail 24/7 without the generator (if the days are sunny OC). And adding the kityake, well that will top up the speed depending of the wind. For me that sounds all nice
Roy Moon That’s excellent when you go from the US to Europe. You just follow the stream and don’t have to care about areas with no wind😎. And when going the other direction, you simply avoid it and turn on the generator when you cross it. Well, I honestly don’t think the boats purpose is to make passages on a daily basis. It’s possible to make long passages, but when at destination it is (according to me) an ideal vessel to island hop. I see it like convenient as a motorboat with advantages of a sailboat.
as a person that enjoys boating I can attest that the main 2 drawbacks when driving a boat is 1) the noise of the motor 2) paying for the gas silent yachts is for sure hitting a really niche market (not many people can afford 1.5 million dollar boats) but the overall EV boat market is sure to grow rapidly over the years.
Cost of fuel is cheap compared to the cost of replacing the battery pack. And as far as noise goes, any lengthy time under power will require the diesel generator to kick in.
@@stevenf927 Fuel ...Not now it isnt certainly in many countries and it will get a lot worse .. fast because the oil companies will want to ring as much out the burners as they can before time they have to stop because the games over. The battery tech does have to get better and cheaper though ... there are alternatives being tested and on the way. The blade cell bing one step. But also Including the single use 100% recyclable Aluminium air cell. Which gives a very long range for a low wt and uses a common metal thats easy to recycle.
Good for coastal cruising and using in sunny areas. Not practical up north. Great to see technology in solar growing and the use of long life electric motors....would be fun to have in Miami let the Bahamas!!!
@@maryormb1742 I'm assuming that's why OP said "deployable" wind turbines. Meaning that the wind turbines could be folded, retracted, or collapsed in some way when in motion.
Electric Future I understand that but maybe the next video you can do one that is equipped with a kite sail.Would love to see it in action on a Silent yacht.And sorry about your drone
Electric Future I’ve never seen any video of this alleged kite sail. I wrote silent yachts and they linked me to some small company that had videos of initial tests of a prototype that was not ready for production by a long shot.
I was thinking the same thing every time he talked about needing the generator. Sure you want it still, but a few smaller wind turbines on the back or such to snag maybe another few KW hours of power.
As somebody who used to kitebuggy, I can confirm how much power a good aerofoil kite can produce in the right conditions. Highly efficient, as I could regularly achieve speeds at least 1.5 to 2x more than the actual wind speed. Speeds in excess of 80kph easily achieveable with a little 2.5 metre kite! I would suggest that the kites on these boats should be repositioned to be flown beam on, ie 90 degrees to the yacht's direction of travel, as that is where these kites generate the most power, rather than from the bow. They are generally much easier to control when used like this and require a lot less input into controlling them.
@Billy West at 5-6 knots, wind turbines wouldn't create drag. In fact the wind may be blowing faster than that from the aft, such that the turbines are charging facing the rear of the boat, even while underway. I'd add 2-4 turbines, depending on size, placement, and efficiency. Typically when there isn't any sun on the water, there's wind. This would help whether stationary or on the move, day or night.
@Billy West Don't be negative. Wind turbines would be a great addition in certain conditions like when anchored or if you have a big tail wind as he mentioned. I thought similar about both having a wave generator power system and wind turbines.
@Billy West You're completely incorrect. I suggest you look at others that actually do live on their boats and they have small wind turbines and they say they work great. If you've actually worked in any such related field as you claim, I feel bad for you. Not sure if you realize that when people live on their boat, the boat is most often not moving and the wind is blowing... Imagine being anchored in a bay for weeks or months and the wind blowing while you aren't going anywhere... Also when in motion the massive sails collecting wind moving the sailboat forward easily make up for the tiny drag by one or two small wind turbines. Common sense guy.
I would say it is a great idea but will require more speed, weight reduction and space utilization to be effective. I don't think some yacht owners care much about the cost and they want to get to their destination on a timely basis. However, this is just the beginning of solar battery technology and with the improvements in battery technology expected to be announced in the next couple of weeks and years to come this will be a viable option in the future. Those who can adopt these changes into their craft quickly and on a regular basis (like Tesla) will prove to be the big winners.
No you can't. There are no sails here. In fact the host said if there were sails, it would cover up the solar panels. So no. Sail or solar, pick one but not the other.
Top of the line, highest efficiency solar PV panels at 23% from SunPower. Very nice! I have 10 of the 335 watt SunPower panels on my garage which produce 6,000 kilowatt hour annually. They are also Cradle to Cradle Certified for clean disassembly and re-manufacturing. Our renewably powered circular economy in action.
@@johnarizona3820 The average speeds attained by sailing catamarans would be quite similar, especially taking into account that sailing quite often involves tacking, etc., to make effective use of wind. With the electric motors this catamaran would be very similar to sailing (no engine noise, just wind and water) with the advantage of a more direct path, making this craft faster than sailing at similar speeds.
Henry Nymann except that you would be running your generator all the time. Solar only gives you 5 knots for 5.5 hours a day. That’s fine if that fits your range requirements. But sailboats can cross oceans faster without using as much fuel.
@@RogerWilco1 From Silent Yachts: "A SILENT yacht can cruise up to 100 miles a day without fuel, permanently and for weeks featuring virtually unlimited range. SILENT solar power systems feed the electric propulsion of the catamarans (short term speed up to 20kn) and all household energy needs." Granted, to do only 100 miles per day for a full day means travelling at around 4 miles per hour. But, that would be always in a straight line, and non-stop. Also, multi-day passages are only sporadically done, for the purpose of getting to another destination where one would stay for a while.
Yes sail boat but you do what they did on the black pearl but not sails as such those bendable panels on top of the sail so you also get sun and wind in one shot then when you fold down the sail you have your deck full of panels like it is.
The way of the future, I can't wait to see a solar powered airplane. Just think since you are flying above the clouds it's endless sunshine which equals endless power.
To the "real sailors". Think about how many days you spent waiting for the right winds and how much hours you travel on engines during Atlantic crossing for example? I know for sure one crossing which took 600 h of engines running?!?!
Sail boats cant always sail in the right direction instead zig zaging in close reach. Plus this would allow helm inside the cabin completely out of all weather without the need to be working and changing sails in dangerous storms, at night etc.
I love the idea of solar powered yachts. When he starts talking about the torque necessary for a car vs for a boat, it got me thinking about hydrofoils. One of the reasons why boats require so much more power is because the water is so good at removing momentum due to the amount of frictional surface area in contact. However, hydrofoils have the ability to lift the boat out of the water and reduce the amount of surface area in contact with the water and therefore remove much of the drag. I wonder if there are any solar powered hydrofoil cats on the horizon. I imagine having a hydrofoil would greatly improve power efficiency.
The thing about hydrofoils is you need to expend enough energy to get up to speed where the hydrofoil produces enough lift to get you out of the water. Then you need to keep expending the required amount. Hydrofoils work great on very fast vessels because wind resistance is far lower than water resistance and the amount of lift required only needs to be maintained at a very low level. These vessels also have very high power to weight ratios capable of reaching planing speeds very quickly. A solar powered yacht is on the opposite end of the power to weight ratio spectrum. Low displacement speeds are the best we're going to get for a while on these vessels.
John Arizona it’s kinda weird, $750 to go to Bahamas at high speed, but this boat can’t make it there at 17 knots on its batteries. Free fuel if you go slow- but then the power boat will be pretty cheap if it went slow. On the other hand this boat isn’t that much more expensive to buy than the powerboat.
@@RogerWilco1 It's not 750 at high speed though. You might have been mistaken by the video they showed of a yacht at high speed, but they calculated the $750 with a "2000rpm cruise". Cruising rpm is the most efficient rpm for that particular engine, which would probably be around 5 to 7 knots. When you drive a gas powered boat that size at higher speed you are looking at a much higher fuel consumption, and I mean waaaaayyy higher.
Great idea to beat the cost of fuel and extend the cruising and live aboard capabilities. Yamaha has just introduced the most powerful electric motors, that could be a real boon to this yacht. I would suggest that the cabins or Spartan and need a serious interior design with some fine wood finishes. The tri-decker enclosed is a winner. Great advance in the marine world. 🙏🐻
Beating the cost of fuel would buch better done with sails. This boat as the narrator said can do 7mph for one hour under its own power. After that it's diesel. Where are the sails? Sorry, but sails work better for boats than solar. Do you really wanna spend a long distance trip going 7 miles, stopping yo fully recharge (who knows how long that takes) and the going another 7 miles? For the whole trip? Otherwise you're burning diesel like all the other yachts. This is a farce. This is a diesel yacht with auxiliary solar power at best.
One of the best technical tours of this boat I have seen. Thank you. Am I correct in hearing that it can cruise @ 6knots for 60 miles until the batteries are empty?
It can probably cruise at 6knots indefinately as long as the sun is shining and giving them 10kW. But they I notice all up he is pretty sly and doesn't actually say. It could be that you can cruise at 6 knots using 10kW from solar, and 20kW from batteries. Who knows. Why does he have a 150kW electric motor? Most likely this is boat is used for 1 hour trips and thats it.
How long would it take for the solar panels to fill those huge battery packs? Does it plug into shore power to speed up the charge process? Lots of unanswered questions. Cool concept, tho. Love the kite.
Well battery is 140Kwh and there are 10Kwh of solar panels. So at peak generation 14 hours but realistically 2 to 3 days as no sun at night. I imagine it would have a shore power inverter.
@@theoysterman1 Solid info, thanks. Presumably the batteries don't get that low on a regular basis, you charge them up when at port and run the motor slowly enough for them to not discharge all the way before your destination. I love this concept, I love that it appears to work so well with no sacrifices, and even some big benefits like silent running.
The thing is so long as the panels generate electricity the boat will run. At 10Kwh it will run at 5knot without battery draw. Theoretically you coukd run at say 2 knots and charge batteries at the same time. If you don't mind slow and like quiet this would be ideal.
Very nice boat. A few years ago, I was living in the caribbean and it would have been a very nice alternative to a house. Low speed is not an issue, since if you add a starkink connection all the family can work and study and be entertained. Furthermore, with the challenge of fighting climate change, the only alternative is sailing, probably with quite less comfort and space.
@@greglastname4453 Sure, and 99% of climate science is wrong. And IPCC experts are paid by China to destroy the USA, as if the USA need anybody to crash. And off course Biden is a robot controled by China since the USA has signed the Paris agreement. Etc.
It’s not really proper to call it unlimited range. You can’t safely cross an ocean on these without a lot of diesel. The solar panels (at 10kW as you claim) will only gather 5-6 hours of running time, a day, so you can’t travel 24 hours. And if they are powering the motor at 5 knots, they can’t charge the batteries as well. 8-10kW required to go 5 knots, only 10kW of panels. But thanks for making a video in the technical details of this boat. Got some facts I hadn’t been able to find out before.
You can cross the ocean. the Solarwave 64 the precursor to this model did cross from spain to the US in 2017. In solar only mode your average speed is similar to a sail boat.
Jean-Marc Zanni Sure, you can cross the ocean using diesel. But not solar. They are misleading about this and it makes the company look dishonest. You can’t do it just using sun, not safely. Even if you ignore currents and wind- and if you ignore them, you are being unsafe- the math doesn’t work. A whole days charging gets you only a few hours run time. 5 knots costs 8-10kW. Let’s assume the wind and currents are a non issue and it’s only 8kw. Day one: 210kwh in batteries are start. You make 50kwh from the solar panels for the full day, giving you a supply of 260kwh total. 24 hours at 5 knots costs 192kwh Day two starts and you have 260-192kwh=68kwh in your batteries. That day you have perfect sun again and get an additional 50kwh from your solar panels That means your budget for that day is 118kwh. 118kwh @ 5knots/8kw gives you 14.75 hours running time. Now it’s night. Your batteries are tapped out, and there’s no solar power, so you have to run the generator overnight. Day 3: Sun comes up. You’ve been running the generator. At best you have burned though diesel to fill the bank completely and run the motors. That puts you at the day 1 scenario again. This means you are running the generator %25 of the time - 12 out of every 48 hours- and only making 5 knots And praying you don’t have wind or current or a cloudy day. Any of that and you’re running the generator more.

Loanword Eggcorn No, I never said anything about sailboats. Stop lying. I never said they didn’t cross an ocean either. Lying about what I said and then saying “facts are facts” when the facts directly from Silent Yachts President proves you wrong is pretty rich. And pretty stupid. The fact is, crossing an ocean requires running a generator more than %25 of the time, based on the numbers given by the companies president. Stop lying.
Dont forget the costs of the batteries, replacement and upkeep. The upfront cost of the panels can be amortized since they last, but batts are expensive / not as expensive as fuel, but a consideration.
@ 2:45 he says you can go 60 miles at 6 knots. That must be the capacity of the batteries before they need a recharge. So if you want to go further than that you are running the generator?
I feel like that would be the ultimate goal, but we need to make super flexible solar cells before that happens. We already have flexible ones, but they can only bend so much
Of course if you had sails you wouldn't need that much area of solar panels, simply enough to top off your cruising/marina motor. Of course you could just plaster the deck with solar panels like this as well, the Sun will only be blocked on part of the deck anyways by the sail, and in the case of no wind, bring down the sail and all the panels can charge up.
@@kek207 It's aimed at a completely different public with a completely different set of skills. And the point of such a boat is to enjoy the ocean. If you want to go fast, use a car or a plane.
@@uputku yes but the problem is: sailboats are designed to last more than 20 years. This thing is done after 5-10 years. Why? The battery technology is advancing at quite a fast pace. Why would you want to buy that if you can go cheaper, faster and more efficient once solid state batteries come out?
@@uputku yeah thats true but people who can spend 2 million dollars on that thing will have enough money for a crew man who does the work for you. That's the problem. Why would you wanna use the power of the sun? It's slow, unreliable and inefficient. Wind however is almost always there. So what's the point of having a solar boat if you have to use your diesel generator to get from point A to point B?
FusionFall If you’re amazed by the space/floor plan, most catamarans (power or sail) of that size use the exact same layout. I think it’s a cool proof of concept, but I would wait for better things to come.
I live in the tropics where we have lots of thunder storms with hail stones. Won't the hail stones destroy the solar panels? Also what maintenance is required for the solar panels and how easy are they to maintain? Birds will be defecating on the panels making them less effective as will salt caking on top of the panels. How much does it cost to replace defective solar panels? I never hear these questions being asked.
That's because most boaters have weather analysis systems aboard to detect and avoid storms. Also, all boats need regular fresh water washdowns to avoid corrosion. Pricing depends on a whole host of market and design variables.
amazing. Can't wait to see them implement Hydropower with fuelcells instead of that combusiton engine. Would produce drinking water on top of storing energy for that long range.
The Hybrid Electric-Diesel Gen system makes a lot of sense. If you price out a luxury sailing cat of 55' it's very expensive also. Solar and battery technology advancements will make boats like this more common in the future. I wonder if a scaled down 45' version works and what the cost would be. Using a wind gen seems to be logical but they make a lot of noise.
@@jaysparc I hope you don't shit on people all the time for no reason, that's remarkably dimwitted. Its actually quite a good idea - like how rockets use chemical propellants to get to space and then switch to ion engines for long missions.

It needs to be combined with a sailing rigging. On their Atlantic crossing they still burned hundreds of gallons of diesel to run the generators when the cloud cover ran the batteries down, and I would be willing to bet that during that time there was plenty of wind. This boat with sails on it could travel the world without a drop of fuel.
I love it how Tesla became a generalization for every thing going electric with batteries. Imagine he would always say. “Batteries like an RC car”, “ Motor like am RC car”

@@MichaelNNY It's not really a boat by engineers either, just listen to the video again, the engineer clearly explains why solar isn't good for boats and why this boat requires a diesel motor to actually go anywhere.

I absolutely these boats, interested in one day getting a silent 60. The cost around 2.2+ but they do need to bump up their "intererior" for what they are charging. It's nice, but it's still looks like a floating Ikea.
I think tech is amazing, but id have sails as a backup atleast. But sailing La vagabonde and Gretta would be proud though lol, probably they're next boat lol. I was about to make a comment and then i seen yours .
When buying a boat add up all the cost. Purchase price, maintenance, estimated repairs, running cost, insurance, etc. Calculate the total then double it. Because, when it comes to boats, if you can't afford to buy/run two, you can't afford to buy/runone.

This would be a great boat for someone who wants to cruise the Caribbean but dosen't want to do around the world cruising. Great vid!
I can definitely see the value of totally silent propulsion, although I don't think fuel cost is big at displacement speeds. I only fill my sailboat's diesel tank every two years. The part I can see as a plus is the total silence. Most people agree the best time on a sailboat is when the sails are pulling and the engine is shut off. Beautiful silence.
i grew up sailing with my dad, and you hit it on the head. the minute when the boat settles in . gets happy and picks up a little heel, its just magic.
Maybe the sail version is the best option even if the guy says it is the worst. You could charge the batteries with shore power and use the electric motors only around the mooring or when the wind drops, otherwise use the sails predominantly. The panels can power the creature comforts. Just a sail boat really but with lower maintenance motors.
Solar price has come down a lot. When storage of power follow, this set up makes perfect sense.
Solar panels need to be more efficient for this to be viable, not enough sq footage to generate the power needed.
Dim Sum how much is the price

I love this boat! It's really fabulous! No fuel anymore. And silent. Chapeau!
Did you see the same video as me? Where did you see "no fuel anymore"? This boat can go 6 knots for 60 minutes under its own power under absolutely ideal conditions with full battery. And had no sails. What do you think happens after that? The zillionaire on-board waits two days to recharge to go another 7 miles? No. They burn diesel the rest of the way like everyone else. These solar panels come at the cost of sails. That is a grave cost.

Sure would love to see the 80 footer on here. 👍😁
I didn't know they had electric yachts. I think this is the best one I have seen electric or other wise. I love the style and simplicity of it.
THAT is MY kind of Yacht! BRAVO!
I looked at the Silent Yachts website and at least on the 50 footer they use a pod-drive setup. Something they _DON'T_ list for any of their models is the "air-draft" or bridge clearance. If it's under 15 feet this would be _THE_ perfect "Looper" boat. The power configuration that _I_ would want is: 2x 50kW motors, 300kWh (or larger) battery bank and 150kWh genset.

This is interesting tech for a couple reasons: 1) Pretty soon we'll have batteries that hold twice the capacity. 2) Lighter weight composites using graphene might make it possible to put this boat on hydroplanes. Then you do your Bahamas trip at 25 knots instead of 6 knots.

If it can do 17knotts thats a lot faster than some so called performance yatchs and you could make it go faster just by sacrefising space in the hulls or extending the hull water line .... and stripping out all wt Like racing boats.. but i sure as hell wouldnt want to live for weeks or months on one. This is your holliday or full time off grid home and window on the world.
EV motors just trash ICE motors
In so many ways thats why the first vehicle to reach a 100kph 60mph was electric.. they can run in reverse and even run regen and an average bloke can man handle one in and out a boat try doing that with a 250-600 hp equivalent diesel engine.
If you want fast, look at the foiling electric launches which use 2/3 less power when foiling than a displacement hull. 🤷♂️
If you want a race sail boat there are already Katanas etc being built with hybrid and limited electric systems..
Telescopic rigid wing sails are probably more efficient than trad, sails and given some materials advances a lot less hassel.
That sounds like so much money but then I remember how much a house costs. I would way prefer to live on a yacht like this.
I'm sure yacht maintenance is considerably higher than an average house.
got any idea how much mooring are ,trying to think what it would be like on a rough day ,stay in your house and buy a jet ski much more fun.
You're not factoring maintenance costs.
@@KentSpain85 Silent yachts like this have about the same kind of maintenance as a regular house, except, you don't have to pay for the electric bill, so... technically, it's better than a house. :P
if a yacht is better than a house then why dont you see the average person buying yachts instead of houses? the target demographic for yachts are millionaires. they're a luxury
Been watching videos about boats for a while now and this is the closest to what I'm looking for. In 10 years I still won't be able to afford this one, but it gives me hope that my perfect boat may some day become a reality
pretty much the perfect yacht, not cheap, but worth every penny....IMO
checkout the website and the warranty. It is better than most new home warranties.
I don't think 5-6 knots the perfect yacht. In the real world I don't see anyone sailing this thing across the ocean.
Roy Moon
I an other vid, Silent Yachts said that with maximum speed of 4 knots, you can sail 24/7 without the generator (if the days are sunny OC).
And adding the kityake, well that will top up the speed depending of the wind. For me that sounds all nice
@@chukwow5738 Google show the Gulf stream cam reach speeds of 5.6 knts.
Roy Moon
That’s excellent when you go from the US to Europe. You just follow the stream and don’t have to care about areas with no wind😎.
And when going the other direction, you simply avoid it and turn on the generator when you cross it.
Well, I honestly don’t think the boats purpose is to make passages on a daily basis. It’s possible to make long passages, but when at destination it is (according to me) an ideal vessel to island hop.
I see it like convenient as a motorboat with advantages of a sailboat.
as a person that enjoys boating I can attest that the main 2 drawbacks when driving a boat is 1) the noise of the motor 2) paying for the gas
silent yachts is for sure hitting a really niche market (not many people can afford 1.5 million dollar boats) but the overall EV boat market is sure to grow rapidly over the years.
Cost of fuel is cheap compared to the cost of replacing the battery pack. And as far as noise goes, any lengthy time under power will require the diesel generator to kick in.
@@stevenf927
Fuel ...Not now it isnt certainly in many countries and it will get a lot worse .. fast because the oil companies will want to ring as much out the burners as they can before time they have to stop because the games over.
The battery tech does have to get better and cheaper though ... there are alternatives being tested and on the way. The blade cell bing one step. But also Including the single use 100% recyclable Aluminium air cell. Which gives a very long range for a low wt and uses a common metal thats easy to recycle.
The boat is amazing, but did you see that dolphin at 10:18 ?? :)
I saw it
I'm for sure going to own one of those sweethearts in the future!
Wonderful video! So nicely filmed and presented. This is the first time I have heard of kite propulsion, but I love it! well-done! I have subscribed!
Same!
Very cool the speed is perfect. It's a yacht not a speed boat, it's about the journey not the destination, that's what planes are for.
Even though i cant afford one, im still waiting for the owners of those to film their voyages and share the insights, like.. real owners..
you can totally make this yourself, if you really want it
Good for coastal cruising and using in sunny areas. Not practical up north. Great to see technology in solar growing and the use of long life electric motors....would be fun to have in Miami let the Bahamas!!!
Seems like deployable wind turbines would be a great asset for all the small stuff.
I agree and maybe higher altitude wind generators would be even better ua-cam.com/video/pYv6k5A-kHg/v-deo.html
They already do. Modern sailboat yachts are equipped diesel engines, wind turbines & battery banks for redundancy.
Small Wind turbines to generate electricity while it's docked or there's no sunshine. Possibly help power the lights?
@@maryormb1742 I'm assuming that's why OP said "deployable" wind turbines. Meaning that the wind turbines could be folded, retracted, or collapsed in some way when in motion.
Great idea , the drag coefficient would create more energy than would be lost
I will never be able to afford a boat like this. However, I fully appreciate the tech and scope of sailing something like this. Happy Trails

Next video maybe show the deployment and retrieval of the kite sail.
This model was not equipped with a kite option.

Definitely will film the kite if I get the opportunity
Electric Future I’ve never seen any video of this alleged kite sail. I wrote silent yachts and they linked me to some small company that had videos of initial tests of a prototype that was not ready for production by a long shot.
@@RogerWilco1 I found this similar idea in production: ua-cam.com/video/pYv6k5A-kHg/v-deo.html
That was v informative, largely because the guy was refreshingly frank.
I would add a folding wind turbine to extend the power!
wind turbine for windy day and solar for sunny makes sense.
@@rhianngacusan1227 That's a very wise decision.
It's already been done just on a smaller scale !
ua-cam.com/video/2FbGKQbWlYc/v-deo.html
I was thinking the same thing every time he talked about needing the generator. Sure you want it still, but a few smaller wind turbines on the back or such to snag maybe another few KW hours of power.
Wind turbines are prone to break down, take more room then it’s solar power counterpart, and caused drag making the boat less efficient.
As somebody who used to kitebuggy, I can confirm how much power a good aerofoil kite can produce in the right conditions. Highly efficient, as I could regularly achieve speeds at least 1.5 to 2x more than the actual wind speed. Speeds in excess of 80kph easily achieveable with a little 2.5 metre kite! I would suggest that the kites on these boats should be repositioned to be flown beam on, ie 90 degrees to the yacht's direction of travel, as that is where these kites generate the most power, rather than from the bow. They are generally much easier to control when used like this and require a lot less input into controlling them.
Why not compensating with wave propulsion and wind turbine or a kite?
@Billy West at 5-6 knots, wind turbines wouldn't create drag. In fact the wind may be blowing faster than that from the aft, such that the turbines are charging facing the rear of the boat, even while underway.
I'd add 2-4 turbines, depending on size, placement, and efficiency. Typically when there isn't any sun on the water, there's wind. This would help whether stationary or on the move, day or night.
@Billy West Don't be negative.
Wind turbines would be a great addition in certain conditions like when anchored or if you have a big tail wind as he mentioned.
I thought similar about both having a wave generator power system and wind turbines.
@Billy West You're completely incorrect.
I suggest you look at others that actually do live on their boats and they have small wind turbines and they say they work great.
If you've actually worked in any such related field as you claim, I feel bad for you.
Not sure if you realize that when people live on their boat, the boat is most often not moving and the wind is blowing...
Imagine being anchored in a bay for weeks or months and the wind blowing while you aren't going anywhere...
Also when in motion the massive sails collecting wind moving the sailboat forward easily make up for the tiny drag by one or two small wind turbines.
Common sense guy.
and that is a correct way to do a hybrid! only electric propulsion but with generator
100%

Spot on👍
I’m soo in love in this yacht.
I would say it is a great idea but will require more speed, weight reduction and space utilization to be effective. I don't think some yacht owners care much about the cost and they want to get to their destination on a timely basis. However, this is just the beginning of solar battery technology and with the improvements in battery technology expected to be announced in the next couple of weeks and years to come this will be a viable option in the future. Those who can adopt these changes into their craft quickly and on a regular basis (like Tesla) will prove to be the big winners.
very cool boat! I love that you can sail by wind as well.
sails would block the sun from panels, but you could figure out a way to have the sails pulling the boat, the way spinnakers do.
No you can't. There are no sails here. In fact the host said if there were sails, it would cover up the solar panels. So no. Sail or solar, pick one but not the other.
Top of the line, highest efficiency solar PV panels at 23% from SunPower. Very nice! I have 10 of the 335 watt SunPower panels on my garage which produce 6,000 kilowatt hour annually. They are also Cradle to Cradle Certified for clean disassembly and re-manufacturing. Our renewably powered circular economy in action.
Motivation. I will own one of these.
It only goes 6 knots. If your going to dream, dream better. 1.5 million for the worst one.
@@johnarizona3820 The average speeds attained by sailing catamarans would be quite similar, especially taking into account that sailing quite often involves tacking, etc., to make effective use of wind. With the electric motors this catamaran would be very similar to sailing (no engine noise, just wind and water) with the advantage of a more direct path, making this craft faster than sailing at similar speeds.
Henry Nymann except that you would be running your generator all the time. Solar only gives you 5 knots for 5.5 hours a day. That’s fine if that fits your range requirements. But sailboats can cross oceans faster without using as much fuel.
@@RogerWilco1 From Silent Yachts: "A SILENT yacht can cruise up to 100 miles a day without fuel, permanently and for weeks featuring virtually unlimited range. SILENT solar power systems feed the electric propulsion of the catamarans (short term speed up to 20kn) and all household energy needs."
Granted, to do only 100 miles per day for a full day means travelling at around 4 miles per hour. But, that would be always in a straight line, and non-stop. Also, multi-day passages are only sporadically done, for the purpose of getting to another destination where one would stay for a while.
I'd rather make one
Nice concept. I'm looking forward to 20%+ efficiency solar sails. That would be a great combination.
Yea. Sails made of thin film collectors that can be furled and unfurled and a regenerative motor would be optimal.
Hmm if only there were a way to combine this electric drive system with wind powered propulsion to increase daily range.
It’s called a sailboat. Yes people do this.
You still want a diesel generator of course.
@@-John-Doe- I was being sarcastic m8.i am fully aware sailboats exist.
Yes sail boat but you do what they did on the black pearl but not sails as such those bendable panels on top of the sail so you also get sun and wind in one shot then when you fold down the sail you have your deck full of panels like it is.
You can achieve better propulsion using worm gears engine which will give you extra York,power even with less solar panels;!
kite
The way of the future, I can't wait to see a solar powered airplane. Just think since you are flying above the clouds it's endless sunshine which equals endless power.
They already flew trans-Global back in 2015.
To the "real sailors". Think about how many days you spent waiting for the right winds and how much hours you travel on engines during Atlantic crossing for example? I know for sure one crossing which took 600 h of engines running?!?!
Gorgeous. I would spend a lifetime traveling.
I absolutely love this little ship! I could never afford one, but it is beautiful.

Beats buying a home for the same price. Live on the sea!! 😊
Just have to watch out for the pirates.
I love the idea of solar powered yachts. When he starts talking about the torque necessary for a car vs for a boat, it got me thinking about hydrofoils. One of the reasons why boats require so much more power is because the water is so good at removing momentum due to the amount of frictional surface area in contact. However, hydrofoils have the ability to lift the boat out of the water and reduce the amount of surface area in contact with the water and therefore remove much of the drag.
I wonder if there are any solar powered hydrofoil cats on the horizon. I imagine having a hydrofoil would greatly improve power efficiency.
The thing about hydrofoils is you need to expend enough energy to get up to speed where the hydrofoil produces enough lift to get you out of the water. Then you need to keep expending the required amount.
Hydrofoils work great on very fast vessels because wind resistance is far lower than water resistance and the amount of lift required only needs to be maintained at a very low level. These vessels also have very high power to weight ratios capable of reaching planing speeds very quickly. A solar powered yacht is on the opposite end of the power to weight ratio spectrum. Low displacement speeds are the best we're going to get for a while on these vessels.
The fuel savings are pretty nice, if you can afford to buy one in the first place $$$
What fuel savings? You pay millions to start.
John Arizona it’s kinda weird, $750 to go to Bahamas at high speed, but this boat can’t make it there at 17 knots on its batteries.
Free fuel if you go slow- but then the power boat will be pretty cheap if it went slow.
On the other hand this boat isn’t that much more expensive to buy than the powerboat.
@@RogerWilco1 It's not 750 at high speed though. You might have been mistaken by the video they showed of a yacht at high speed, but they calculated the $750 with a "2000rpm cruise". Cruising rpm is the most efficient rpm for that particular engine, which would probably be around 5 to 7 knots.
When you drive a gas powered boat that size at higher speed you are looking at a much higher fuel consumption, and I mean waaaaayyy higher.
same same for EVs
@@jsmit9484 A Freeman 47 and 37 will cruise at 40-60mph while burning 1.3-0.8 gph.
Great idea to beat the cost of fuel and extend the cruising and live aboard capabilities. Yamaha has just introduced the most powerful electric motors, that could be a real boon to this yacht. I would suggest that the cabins or Spartan and need a serious interior design with some fine wood finishes. The tri-decker enclosed is a winner. Great advance in the marine world. 🙏🐻
Beating the cost of fuel would buch better done with sails. This boat as the narrator said can do 7mph for one hour under its own power. After that it's diesel. Where are the sails? Sorry, but sails work better for boats than solar. Do you really wanna spend a long distance trip going 7 miles, stopping yo fully recharge (who knows how long that takes) and the going another 7 miles? For the whole trip? Otherwise you're burning diesel like all the other yachts.
This is a farce. This is a diesel yacht with auxiliary solar power at best.
One of the best technical tours of this boat I have seen. Thank you. Am I correct in hearing that it can cruise @ 6knots for 60 miles until the batteries are empty?
Yes I believe so.
It can probably cruise at 6knots indefinately as long as the sun is shining and giving them 10kW. But they I notice all up he is pretty sly and doesn't actually say. It could be that you can cruise at 6 knots using 10kW from solar, and 20kW from batteries. Who knows. Why does he have a 150kW electric motor? Most likely this is boat is used for 1 hour trips and thats it.
How long would it take for the solar panels to fill those huge battery packs?
Does it plug into shore power to speed up the charge process?
Lots of unanswered questions. Cool concept, tho. Love the kite.
Well battery is 140Kwh and there are 10Kwh of solar panels. So at peak generation 14 hours but realistically 2 to 3 days as no sun at night. I imagine it would have a shore power inverter.
@@theoysterman1 Solid info, thanks. Presumably the batteries don't get that low on a regular basis, you charge them up when at port and run the motor slowly enough for them to not discharge all the way before your destination.
I love this concept, I love that it appears to work so well with no sacrifices, and even some big benefits like silent running.
The thing is so long as the panels generate electricity the boat will run. At 10Kwh it will run at 5knot without battery draw. Theoretically you coukd run at say 2 knots and charge batteries at the same time. If you don't mind slow and like quiet this would be ideal.
Good direct Infos on this beast
Beast? You mean POS. A sailboat is 4X as fast...
I would be soooo content with this cat. Awesome!

Very nice boat. A few years ago, I was living in the caribbean and it would have been a very nice alternative to a house. Low speed is not an issue, since if you add a starkink connection all the family can work and study and be entertained. Furthermore, with the challenge of fighting climate change, the only alternative is sailing, probably with quite less comfort and space.

It’s not really proper to call it unlimited range. You can’t safely cross an ocean on these without a lot of diesel. The solar panels (at 10kW as you claim) will only gather 5-6 hours of running time, a day, so you can’t travel 24 hours. And if they are powering the motor at 5 knots, they can’t charge the batteries as well.
8-10kW required to go 5 knots, only 10kW of panels.
But thanks for making a video in the technical details of this boat. Got some facts I hadn’t been able to find out before.
You can cross the ocean. the Solarwave 64 the precursor to this model did cross from spain to the US in 2017. In solar only mode your average speed is similar to a sail boat.
Jean-Marc Zanni Sure, you can cross the ocean using diesel. But not solar. They are misleading about this and it makes the company look dishonest.
You can’t do it just using sun, not safely. Even if you ignore currents and wind- and if you ignore them, you are being unsafe- the math doesn’t work.
A whole days charging gets you only a few hours run time.
5 knots costs 8-10kW. Let’s assume the wind and currents are a non issue and it’s only 8kw.
Day one:
210kwh in batteries are start. You make 50kwh from the solar panels for the full day, giving you a supply of 260kwh total.
24 hours at 5 knots costs 192kwh
Day two starts and you have 260-192kwh=68kwh in your batteries. That day you have perfect sun again and get an additional 50kwh from your solar panels
That means your budget for that day is 118kwh.
118kwh @ 5knots/8kw gives you 14.75 hours running time.
Now it’s night. Your batteries are tapped out, and there’s no solar power, so you have to run the generator overnight.
Day 3: Sun comes up. You’ve been running the generator. At best you have burned though diesel to fill the bank completely and run the motors. That puts you at the day 1 scenario again.
This means you are running the generator %25 of the time - 12 out of every 48 hours- and only making 5 knots
And praying you don’t have wind or current or a cloudy day.
Any of that and you’re running the generator more.

Cool ! Love the Kite set up one the best !

Dont forget the costs of the batteries, replacement and upkeep. The upfront cost of the panels can be amortized since they last, but batts are expensive / not as expensive as fuel, but a consideration.
I would live in this!
If someone is feeling gracefull enough, I would love it as a present. Thank you very much.
Imagine what will happen when Solar panels get to 60% efficiency?
I think panels already exist which are approaching that efficiency, the issue being the increased cost
The ISS panels are still the most efficient out there and they are about 40% and they don't even have atmospheric disturbances to deal with
@ 2:45 he says you can go 60 miles at 6 knots. That must be the capacity of the batteries before they need a recharge. So if you want to go further than that you are running the generator?
Imagine having sails made of solar panels so you could use wind and sun at the same time.
I feel like that would be the ultimate goal, but we need to make super flexible solar cells before that happens. We already have flexible ones, but they can only bend so much
@@scottydo5282 flexibility isn't necessary for sails, Google "wingsails"
Those already exist but their efficiency is around ~10%. if that.
Of course if you had sails you wouldn't need that much area of solar panels, simply enough to top off your cruising/marina motor. Of course you could just plaster the deck with solar panels like this as well, the Sun will only be blocked on part of the deck anyways by the sail, and in the case of no wind, bring down the sail and all the panels can charge up.
Hell on top of that wrap the hull im solar panels also lol, wont be as efficient but one side of the time but would help .

@@uputku yes but the problem is: sailboats are designed to last more than 20 years. This thing is done after 5-10 years. Why? The battery technology is advancing at quite a fast pace. Why would you want to buy that if you can go cheaper, faster and more efficient once solid state batteries come out?
@@uputku yeah thats true but people who can spend 2 million dollars on that thing will have enough money for a crew man who does the work for you. That's the problem. Why would you wanna use the power of the sun? It's slow, unreliable and inefficient. Wind however is almost always there. So what's the point of having a solar boat if you have to use your diesel generator to get from point A to point B?
FusionFall If you’re amazed by the space/floor plan, most catamarans (power or sail) of that size use the exact same layout. I think it’s a cool proof of concept, but I would wait for better things to come.
I live in the tropics where we have lots of thunder storms with hail stones. Won't the hail stones destroy the solar panels?
Also what maintenance is required for the solar panels and how easy are they to maintain? Birds will be defecating on the panels making them less effective as will salt caking on top of the panels.
How much does it cost to replace defective solar panels?
I never hear these questions being asked.
That's because most boaters have weather analysis systems aboard to detect and avoid storms. Also, all boats need regular fresh water washdowns to avoid corrosion. Pricing depends on a whole host of market and design variables.
amazing. Can't wait to see them implement Hydropower with fuelcells instead of that combusiton engine. Would produce drinking water on top of storing energy for that long range.
The Hybrid Electric-Diesel Gen system makes a lot of sense. If you price out a luxury sailing cat of 55' it's very expensive also. Solar and battery technology advancements will make boats like this more common in the future. I wonder if a scaled down 45' version works and what the cost would be. Using a wind gen seems to be logical but they make a lot of noise.
Why not have a hydrofoil that used a conventional motor to get out of the water, and then switch to electric motors to maintain speed?
I hope you don't teach engineering. Your supposition is remarkably dimwitted.
@@jaysparc I hope you don't shit on people all the time for no reason, that's remarkably dimwitted. Its actually quite a good idea - like how rockets use chemical propellants to get to space and then switch to ion engines for long missions.
You can run a foil between the hulls to create lift to reduce drag, but they can be annoying in rough weather, but just getting rid of the flat front on the boat would do the same,
Very nice. We hope to save up money to buy one soon.
Ooooor you could use sailboats powered by wind, like they have been for thousands of years.

Be autonomous with free energy supplies, to travel all around the world, that's a nice promise for the future.
Electric Future you show us one of the best tubes if not the best to inspire us of a brighter future world, that's why I share it on the FaceBook group "Future World" and hope that will increase the number of your subscribers to be with us for even longer.
Cost of a jet and speed of a bicycle, almost as slow as my apartment.
It needs to be combined with a sailing rigging. On their Atlantic crossing they still burned hundreds of gallons of diesel to run the generators when the cloud cover ran the batteries down, and I would be willing to bet that during that time there was plenty of wind. This boat with sails on it could travel the world without a drop of fuel.
*More Electric Yachts* ⚡️🛥

Electric just isnt there yet ... getting there but not quite yet
I can’t wait to see what kind of electric yachts will have available 10 years from now
Great video ua-cam.com/video/5vnAQWsCSUQ/v-deo.html
I love it how Tesla became a generalization for every thing going electric with batteries.
Imagine he would always say. “Batteries like an RC car”, “ Motor like am RC car”
It looks like the interior living spaces of this boat was designed by electrical engineers. Needs an interior design that makes it look and feel with some degree of creativity .
Yeah this is a boat by engineers, not interior designers. Very cold and utilitarian. For 1.5 mil, I want a fully solar boat AND a gorgeous boat.
But I love the practicality :O
No need for that designer crap
@@MichaelNNY It's not really a boat by engineers either, just listen to the video again, the engineer clearly explains why solar isn't good for boats and why this boat requires a diesel motor to actually go anywhere. I'd call this a marketing gimmick boat where the sales people thought they could sell a "solar yacht" to people that didn't know any better.
I liked it. Do not like the ornaments and kitsch of many regular yachts.
I absolutely these boats, interested in one day getting a silent 60. The cost around 2.2+ but they do need to bump up their "intererior" for what they are charging. It's nice, but it's still looks like a floating Ikea.
That's Really Very Good And very soon They Will Come Up With More Better Idea Really Ioveit
I would like to see what Riley and Alaina think of this.
I think tech is amazing, but id have sails as a backup atleast. But sailing La vagabonde and Gretta would be proud though lol, probably they're next boat lol. I was about to make a comment and then i seen yours .
When buying a boat add up all the cost. Purchase price, maintenance, estimated repairs, running cost, insurance, etc.
Calculate the total then double it. Because, when it comes to boats, if you can't afford to buy/run two, you can't afford to buy/runone.
"Look at our silent, sexy, zero-emissions* electric yacht!"
*ignore the diesel powered genset that is necessary if you actually want to go anywhere
I do however wonder about stabilization in rough seas! Do we have videos of the ocean crossing mentioned in the video?
