those solar panels are actually really cheap, so to justify a higher price they give you a lifer warranty, which you will need because they won't last that long.
Great series. Very interesting and informative. I've been following silent yachts since the beginning. I think what they're doing is amazing. Slowly but surely their concepts are being adapted by many others as well. You hit the nail on the head by saying sailing boat qualities combined with super yacht comforts
Really great overview of the power generation/useage on the boat. Coming from your background, for a boat to have changed your opinion like that in just 4 days speaks volumes. Thanks Tristan.
Are Silent Yachts considering toroidal props? These can more than double prop efficiency which would make sense on a slow boat like this. They are expensive but no doubt worth it for this application.
Absolutely great yacht and am sure it is a sight into the future. For those of us who don't want to go sailing, who still want to 'motor around', going electric would be a great option. And since this boat is apparently already 6 years old the newest technology must even make her better. Great series this was !
More clean, less energy, "green" energy, less noise, lower maintenance, almost (generator on board) or in fact fully self-sufficient with solar panels and less cost. That was a great video, i hope we can see more of such boats..
Could we hear about any redundancies built into the solar and motors? How many things can go wrong and the boat still be able to limp back to port? Any Achilles heels?
2 motors so if one goes you have a second. The batteries are in 3 sets so I assume they're got their own systems (2 of them are for propulsion 1 for house load) I'm personally curious how it fairs with a lightning strike but they've said they can take a strike and still function. Most configs only have 1 generator but that's a backup system anyways. 2 water makers on most models, they have a surprising level of redundancy (granted there are a bunch of cats with fully redundant systems) I'm not sure what the achilles heel would be... speed? It's not the quickest even with the kite sail, even if the motors are running with generator assistance. Price? Yeah, they're very expensive, some would say overpriced. But I think maintenance and fuel savings will offset that a bit in the long run. Honestly, think of it as a sailless catamaran sailboat as opposed to a powerboat. With new solar and battery technologies on the cusp of release the concept is only going to get more common and the boats are only going to get better (although I think solar propulsion is going to be restricted to cat and tri-hull designs for the near future)
@@KMCA779 Thanks, that echo's my thoughts. It has two dual motors. I wonder what happens if you lose just one of the motors that are paired? It sounds like motors never die but what about the master/slave controller? In a solar system for a house I hear that the inverter is the first thing to die. Those controllers are basically inverters so I'd imagine them suffering in the same way. There's a lot to learn about these things. Not only how they function, but how they malfunction on the seemingly rare occasion.
Cats can and do use a single engine with a slight rudder adjustment to offset torque all the time for efficiency. Electric motors have minimal points of failure compared to marine Diesel engines increasing safety further.
@@carsonc1272 I'm sure they have multiple inverters and charge controllers with milti stage switching for isolating or sharing loads and pv panel groups. I wouldn't be surprised if they had more than 2 inverters and more than 2 charge controllers. I would assume they have a separate grounding system with lightning rod to attract any strikes and the pv systems would all be protected by fusing also.
There are multiple redundancies in the Solar array, each string of panels has its own charge controller, and it's not as simple as "front" or "flybridge" ... otherwise shading just one cell in a panel would bring the entire array down. Google around and get some info on how solar systems actually work, having 13KW of solar panels doesn't mean you'll get anywhere near that, you might average 60%. There is also the generator, which on later boats is much more robust. Another thing to keep in mind is that you never want to run the batteries all the way down to 0 or run them all the way up to 100% ... for the life of the batteries it is best to have them running somewhere between 20-80%. I have also seen a trend with using Kite Sails ... For two electric motors to fail at the same time would be HIGHLY unusual ... you have a much bigger problem ... go find it, and get on your radio!
Hey! 😀I am so happy that you and family could have this wonderful experience. This is amazing! This is my dream yacht, one day maybe i could get a silent yacht.
This yacht's voyage across the Atlantic to the Caribbean was well documented, but thank you for disclosing how much fuel was used. However, it's now back in the Med, so was it moved on a yacht transport ship (like AWOL) or did it cruise on it's own?
Thank you very much for this wonderful and interesting video. This are so many well filmed impressions and honestly every information was given by you. A really impressiv boat. Thank you!
This was very interesting, Tristan, thanks! Although it's not likely, if I ever had a chance to take a cruise, I think I would most enjoy this kind of boat.
It's possible. But mostly lots of different systems are delivered from different suppliers. You need DEEP integration for this, Tesla does this as the only car builder in the world with their super advanced HVAC reusing every bit of heat in the car. :) That's why a Tesla is so efficient in winter.
a 2016 yacht - hopefully motors and systems packaging has improved - independent left and right systems at rear including motor inverters, with all the displays and navigation electronics at the navigation station.
This is the yacht that I have followed on RUclips for a couple or more years. It's unfortunately only available to me curtsy of a lottery win, but I keep trying. Also since I live in the Canaries, I would have it as a live aboard home and not buying a house. Sunshine is available here something like 300 days a year so making it Ideal and easy to crouse around various Islands. I can't remember the last time we had rain. 😅
Thanks, this is exactly the information I was looking for. Fuel burn for a day is pretty amazing. And 77kw of battery is a little light considering that a Tesla has about the same. But overall Silent Yachts seems to have done a good job with the balance.
Remember the boat is 6 years old, most like 8 years counting build time. So 77kW was a lot 8 years ago. New electric 60foot sailing cats are coming with 250kW packs. The tech is only getting better 😎
@@AdventuresonTour the same would have been possible 6 years ago, tech has not gotten substantially better they just realized they need more battery capacity so they did just that.
@@Pixelplanet5 actually the tech had changed greatly in the last 6-8 years. Power density is up nearly 25% in modern cells than it was back than. Plus the addition of built in BMS systems. Along with availability of battery options.
@@AdventuresonTour they are using LiFePO4 batteries, they have certainly not improved by 25% and they are extremely simple in terms of their BMS needs. The main thing holding solar boats back is still that you need insane surface areas to gain enough energy to move a boat and that has not changed at all in the meantime. The only thing that has somewhat improved for cars is the packing density of the cells which increases energy density on pack level but thats not relevant for a boat because space and weight are never any concern on a boat large enough to produce enough solar energy to move that boat. just look at the model S, the 2012 version and the 2022 version still use basically the same cells with the major difference being in 2012 they had 3000mAh of capacity and now they max out at 3500mAh which is only a ~17% increase in 10 years and these are the best cells we have right now, LiFePO4 cells are far below that but are also much cheaper.
@@Pixelplanet5 I've spend the last 25years working and maintaining battery backup systems and battery power heavy duty transportation equipment. I've seen first hand in the feild over the last few years and the improvements are most definitely there... so we'll just agree to disagree, enjoy your day..
Excellent presentation beautiful yacht. My question is the batteries start to decrease in power after four years what is the cost of replacing the batteries and also, where does the waste from the toilets go? Is there a tank that needs to be emptied👍
The newest version has much larger motors, larger arrays and bigger generators. This gives the yacht much higher speeds. If you want to cruise at six knots not a problem. Want to kick it up to 10 knots again not a problem.
Very nice 👌 love the aquaholic wave and with a little more practice you could be as good as nick doing a walk round tour 🤣 very impressed with boat and your tour
Tristen another informative well presented episode, wonderful innovation in boating, and ur so right, everyone wants to get there yesterday. But this boat let's u enjoy life, not just fly threw it. Thanks🇦🇺🌟🌟🌟🌟🌟
I always wonder why Catamarans are open down to the see with that net things. Those are fun for like 10mins and then it's just wasted space. I bet there is a reason for that, but I didn't get it, can some please explain it? Thanks in advance
For showers, the smarter solution is conduction-boiling fixtures. The units cost $200 +- at Alibaba and heat water on-demand ONLY as needed - without limit (assuming you have energy in batteries). This permits zero energy loss hot water without having to store a tank anywhere on the boat, and its cheap too. Does that BlueCool heat pump/air conditioning unit also dehumidify? This might seem pointless at sea and yet it will fight mold spore creation and give you dry towels in your bathroom.s...
What you're asking here is "how much fuel with a completely different design consume", there are far too many variables to answer that question ... go look at Greenline Yachts.
Remember, this is a 6 year old boat. Technology has come a LONG way since then in batteries and solar panels. As a Tesla owner, I can tell you that the great unknown on the Silent boats will be HOW LONG will the battery last?? What happens when it starts to degrade and you lose the ability to charge and move. As the impedance increases, you'll have much less range and speed as battery ages. I am curious as to what the degradation is on the Silent is in the marine environment?? Typically after 4 years or more, the Lithium batteries start to degrade.
Technology has not come a long way in 6 years. Energy density on our best batteries has increased by like 10% at most and thats about it. Solar panels havent changed at all in that time except that they got bígger so they can advertise higher wattage and hope people wont realize. The newer silent yachts use LiFePO4 batteries because they are much cheaper and weight is not a concern anyways so cycle life and degradation is not of any concern. The boat we see in this video can be considered a prototype which will have its own problems because of some weird choices.
@@Pixelplanet5 My concern is that everytime Silent Yachts roll out any kind of ship promotion, its either THIS EXACT ancient yacht because "It crossed the atlantic" or the Silent 60 basemodel. I dont think Ive ever seen anyone do an IRL test of the viability of a Silent 80 EVER. Suspect....
@@TheStaniG thats because zero Silent 80 have been build so far. They could cross the atlantic even without using any fuel, it just takes longer to do so.
Tristan, when you waved in the mirror. Did you say. Hi, I'm a alcoholic or was that just my after hours beverage thinking. Great job on your adventures. 😁👍👍🍺🍺
Tristan, why don't they add one pannel to be vacuume solar water heater? They could save much more energy in that way! By discarding 300W of solar power for warm water I would do any day! One panel would be enough for all 6 onboard.
I can think of a few reasons, but the biggest one was that the whole point is saving the cost of pumping the hot water in a continuous loop. The main reason solar water works is because you can put it high enough up to use its own weight/gravity to feed the hot water. Here you would need those same cyclic pumps. Next is complexity - plus you still need to be able to heat water when the weather is less friendly, and at night. So you would have to build in backup heat that would be less efficient than what they are using now. (its hard to beat "point of use" on -demand for efficiency unless you use a LOT of hot water) Oddly enough, they don't have THAT big of an energy problem on the boat. The biggest reason is that they care about "at-anchor" efficiency is they want to never run the generator -- so the biggest "static" demands are addressed and mitigated. The times they are both under way and running a lot of hot water at the same time are fairly minimal.
Yup , any yacht that both gets away from fuel guzzling engines and tiresome sails , fits into my desires . Its a moveable home , lots to be praised for that .
Great video BUT the word used to describe a twin hull craft is Cataraman - I am hearing you say Catamarang If I am misshearing you I apologise but if not please use the correct terminology
Silent Yacht is a new company. Plus people are REALLY interested in the boats. Of course they're going to do what they can to leverage the interest into sales.
Just asking from a very unexperienced perspective, but wouldn´t it be cool to combine this concept with a sail rig? Or would that take away to much space necessary for the solar panels? Cheers, Martin
Sailing cats are a great use case and in wide production, one of my personal favorites is what Windelo is doing (link below). One of the largest benefits of a sail boat coupled with electric motors is you can turn your prop into hydropower when under sail to offset the amount of solar required. ruclips.net/video/KFDeKYt0SP4/видео.html
The problem is that traditional sails would shade the solar panels. There is an option on the newer models to have a kite sail, the documentation on it isn't the best though. People keep asking but I haven't seen much information on it.
So it's extended range hybrid system. Never running 100% solar at all.Just sail. Or use a kite system. remove the tapelines and make is solar in front. trail 100 floating panel train. in tow in the back. roll it up when returning to port. use a paddle board island material.
1400 liters of gasoline for crossing Atlantic with a "green boat" :)? Are you kidding me? That's above 3k Euro here in Europe. That boat is everything but green energy boat.
@@SuperYachtCaptain I don't deny, i have no experience in boats, i just do the math and to me that's extremly expansive. I know people that bought boats for 5k dollars and they crossed Atlantic with sails. To pay for green boat that much to cross Atlantic it's beyond my comprehension.
A Lagoon 450 has 1,000 liter tank, with an autonomy of 1,800nm. 4l per hour at 5+ knts. The range is never mentioned. So we have to assume around 100nm+. In other words; every few hours, you have to fire up the diesel generator and charge the batteries or wait for the sun to do that (nobody got time for that). This is not ready for any type of crossing. It's meant to be used locally and nothing more. For that purpose, there are better looking power cats. Just get a cat with sails and only use the diesel engine when needed (marina etc.)
Oh the irony! Using an electric boat but carelessly dropping the anchor and obliterating the Posidonia (local marine plants). In 12:42 you can clearly see you dropped your chain and anchor in the dark parts (full of plants) instead of on the sand (clear patches). Please take care of our environment next time you visit our islands.
5kt in a 2-3m swell would not be comfortable, these electro cats can't sustain 15kt for comfort on passage. Ideal for inshore cruising, but not the range for comfortable, offshore passage making. Love your channel.
6:00 seriously? That monster of a motor only produces 20 kW?!? The drive units on my Tesla Model 3 are smaller than that and the stronger one is rated at 190 kW. They also have their own cooling system and they get throttled down fairly quickly when asked for full power, but I think they are able to easily deliver 100 kW continuously. I know it's difficult on a boat to deliver the amount of energy needed for that performance, but I'd assume spending $100k on a big fat battery bank that will deliver that power for a few hours is not that hard (I assume 500 kWh to 1 MWh, 2.5-5 tons) should be possible. An electric motor that is incredibly efficient at the low end (watch Sailing Uma, consuming
I had exactly the same question, but I think the low rpm a propeller needs could also be a reason for the power output. I wonder what the max torque of this motor is.
the motor itself isn't that big - its just encased in that big water jacket for cooling. They made it so that motor can run continuously, where Teslas are limited to a few hours at a time.
Great review. Thanks. And you obviously haven't been married long enough to know that you should be gazing lovingly at your wife first thing in the morning, not out of the window! 😉
It is butt-ugly from the bridge, but not bad looking walking around the main deck. Whoever ordered the zebra wood (?) needs a talking to. Good Review - I like a review from someone who has been aboard a yacht more than a few hours. I liked the smaller cabins better than the master. I do know a way to satisfy most of the problems - Put a sail on it.
One dodgy aspect of such a vessel - IF there is no generator or insufficient fuel - would be that, in bad weather where you have far less opportunity to recharge the batteries that is PRECISELY when you cannot afford to be low or out of power! On the other hand, only a dumb skipper would not allow for that. And we've all seen how idiots can create a catastrophe out of nowhere no matter how well equipped a vessel is!!!
Really cool boat, but this typ of boat is in it baby phase. An Adult would be simmilar to a true motor yatch. Give them about anyothe ten years to develope.
Here’s my issue with the solar only yacht. solar, HEP, and wind power generation on every boat, that would be the ideal sustainable yacht. And a generator with decent just decent fuel tank would be a backup. That’s 4 sources of energy on board. The silent yachts are very poorly built and they charge an arm and a leg for it. Bearing have a far superior power system and just a handful of solar on the roof which does not by any means define the design. The sound of water you hear gnashing against the hull is indicative of the poor build quality and materials of this vessel. If these RUclipsrs would only tell you what they really think, they would never recommend this boat based on the build quality alone
Uhm this boat has Solar and a generator(Like all Silent Yachts, also this boat is from 2016) Wind power creates noise(Watch The O'Kelly's video on it for more info) How would you do HEP on a moving vessel without increasing drag(more drag means more energy usage to keep the same speed

Thats a great Idea..they will be in good hands for sure
those solar panels are actually really cheap, so to justify a higher price they give you a lifer warranty, which you will need because they won't last that long.
here's a guy who's real informative with lots of facts. not a fluff-talker. thank you!
My engineer side is always thrilled with the technical details of the boats... and Silent Yachts really deliver the goods!
Took about five minutes in to this video to convince me I want a solar covered catamaran!

Tristan, why don't they add one pannel to be vacuume solar water heater? They could save much more energy in that way! By discarding 300W of solar power for warm water I would do any day! One panel would be enough for all 6 onboard.
I can think of a few reasons, but the biggest one was that the whole point is saving the cost of pumping the hot water in a continuous loop. The main reason solar water works is because you can put it high enough up to use its own weight/gravity to feed the hot water. Here you would need those same cyclic pumps.
Next is complexity - plus you still need to be able to heat water when the weather is less friendly, and at night. So you would have to build in backup heat that would be less efficient than what they are using now. (its hard to beat "point of use" on -demand for efficiency unless you use a LOT of hot water)
Oddly enough, they don't have THAT big of an energy problem on the boat. The biggest reason is that they care about "at-anchor" efficiency is they want to never run the generator -- so the biggest "static" demands are addressed and mitigated. The times they are both under way and running a lot of hot water at the same time are fairly minimal.
Is there room for a Honda Generator?
Yup , any yacht that both gets away from fuel guzzling engines and tiresome sails , fits into my desires . Its a moveable home , lots to be praised for that .
This is my dream..
Nobody tells how much time dòes it takes for the solar to charge the batteries on board.
can't they have a raffle so I can win a 69ft silent with kite, that wud be lovely..thanks
Excelente channel super good !
Stop being so defensive towards your goal!
My Lost Boat In my Dream.
Great video BUT the word used to describe a twin hull craft is
Cataraman - I am hearing you say Catamarang
If I am misshearing you I apologise but if not please use the correct terminology
The future❤
My question is, why go to so much trouble and expense only to sell it, doesn't make perfect sense, something amiss.
Silent Yacht is a new company. Plus people are REALLY interested in the boats. Of course they're going to do what they can to leverage the interest into sales.
My dream!
Just asking from a very unexperienced perspective, but wouldn´t it be cool to combine this concept with a sail rig? Or would that take away to much space necessary for the solar panels? Cheers, Martin
Sailing cats are a great use case and in wide production, one of my personal favorites is what Windelo is doing (link below). One of the largest benefits of a sail boat coupled with electric motors is you can turn your prop into hydropower when under sail to offset the amount of solar required.

The problem is that traditional sails would shade the solar panels. There is an option on the newer models to have a kite sail, the documentation on it isn't the best though. People keep asking but I haven't seen much information on it.
Question, how does fire risk compare to a conventional vehicle? Lithium batteries at sea. Not my favorite idea.
Well I'm buying a lottery ticket today and if all goes well I will definitely give you a call!
1:00ish
13 kw
- 20kw -20 kw
= 27 kw negative
So what's the boat's name or model?
Silent Yacht 64
Good luck crossing the Atlantic on that
I don't understand why they don't use Water circulating under the solar panels instead of hot water boilers.
So it's extended range hybrid system. Never running 100% solar at all.Just sail. Or use a kite system. remove the tapelines and make is solar in front. trail 100 floating panel train. in tow in the back. roll it up when returning to port. use a paddle board island material.
Why can’t you have a water powered turbine in the hulls to charge the battery
Electric drive for motor yatch wil make sens with fuel cells, not solar panels...
1400 liters of gasoline for crossing Atlantic with a "green boat" :)? Are you kidding me? That's above 3k Euro here in Europe.
That boat is everything but green energy boat.
😂😂, I think you need to learn a thing or 2 about motor yachts and their fuel consumption.
@@SuperYachtCaptain I don't deny, i have no experience in boats, i just do the math and to me that's extremly expansive. I know people that bought boats for 5k dollars and they crossed Atlantic with sails. To pay for green boat that much to cross Atlantic it's beyond my comprehension.
A Lagoon 450 has 1,000 liter tank, with an autonomy of 1,800nm. 4l per hour at 5+ knts.
The range is never mentioned. So we have to assume around 100nm+.
In other words; every few hours, you have to fire up the diesel generator and charge the batteries or wait for the sun to do that (nobody got time for that).
This is not ready for any type of crossing. It's meant to be used locally and nothing more.
For that purpose, there are better looking power cats. Just get a cat with sails and only use the diesel engine when needed (marina etc.)
A sailing cat with a few solar panels would be faster, lighter, and far less expensive and wouldn't need a generator.
Oh the irony! Using an electric boat but carelessly dropping the anchor and obliterating the Posidonia (local marine plants). In 12:42 you can clearly see you dropped your chain and anchor in the dark parts (full of plants) instead of on the sand (clear patches).
Please take care of our environment next time you visit our islands.
5kt in a 2-3m swell would not be comfortable, these electro cats can't sustain 15kt for comfort on passage. Ideal for inshore cruising, but not the range for comfortable, offshore passage making. Love your channel.
6:00 seriously? That monster of a motor only produces 20 kW?!? The drive units on my Tesla Model 3 are smaller than that and the stronger one is rated at 190 kW. They also have their own cooling system and they get throttled down fairly quickly when asked for full power, but I think they are able to easily deliver 100 kW continuously.
I know it's difficult on a boat to deliver the amount of energy needed for that performance, but I'd assume spending $100k on a big fat battery bank that will deliver that power for a few hours is not that hard (I assume 500 kWh to 1 MWh, 2.5-5 tons) should be possible. An electric motor that is incredibly efficient at the low end (watch Sailing Uma, consuming
I had exactly the same question, but I think the low rpm a propeller needs could also be a reason for the power output. I wonder what the max torque of this motor is.
the motor itself isn't that big - its just encased in that big water jacket for cooling. They made it so that motor can run continuously, where Teslas are limited to a few hours at a time.
Just remember this boat is from 2016 quite a lot has changed with Silent Yachts since then,
"16x 200Ah batteries"
If you don't tell me the voltage of those baatteries, that data is unuseful
Batteries wont replace fuel. Need another solution. eg Fuel cell that last 10 years. The big corp wont let that happen.
Great review. Thanks. And you obviously haven't been married long enough to know that you should be gazing lovingly at your wife first thing in the morning, not out of the window! 😉
nope, still burns fuel, even if it's for power - so more like a hybrid.
8 miles per gallon? That's what I calculated.
Hey ………did you get a free bowl of soup with that haircut ?
You never get perfect performance. Always add more panels.
60 square meters of solar!
Could you think 🤔 to use the solar power of this boat, for water 💦 hydrolysis and then use the hydrogen as a fuel? 🦉 😎
It is butt-ugly from the bridge, but not bad looking walking around the main deck. Whoever ordered the zebra wood (?) needs a talking to. Good Review - I like a review from someone who has been aboard a yacht more than a few hours. I liked the smaller cabins better than the master.
I do know a way to satisfy most of the problems - Put a sail on it.
Would negate any advantage of the large array of solar panels(kite system maybe)
@@storm4710 I love my girlfriend doesn't negate the fact that she is fat and ugly. Just saying. All the best, Paul
@@paulinboston I was talking about your idea of putting a sail on it, but hey you do you
I still don't think these electric boats are great yet, a longer battery life and double the speed would be useful. It's getting there though.
Add a kite sail and it would be great! Half the energy consumption + 4-5 knots of speed
this is a 6 year old boat, things have moved on with bigger storage, better panels and bigger motors.
the electric yachts really do work well now.
Haha catamaranges!!!
That would be 370 gallons of fuel
One dodgy aspect of such a vessel - IF there is no generator or insufficient fuel - would be that, in bad weather where you have far less opportunity to recharge the batteries that is PRECISELY when you cannot afford to be low or out of power! On the other hand, only a dumb skipper would not allow for that. And we've all seen how idiots can create a catastrophe out of nowhere no matter how well equipped a vessel is!!!
The ship has a backup generator. Hell the new one rolling off the line soon will be able to have 2 if you want to fork out the money.
Tesla has no solar panels
Really cool boat, but this typ of boat is in it baby phase. An Adult would be simmilar to a true motor yatch. Give them about anyothe ten years to develope.
Here’s my issue with the solar only yacht. solar, HEP, and wind power generation on every boat, that would be the ideal sustainable yacht. And a generator with decent just decent fuel tank would be a backup. That’s 4 sources of energy on board. The silent yachts are very poorly built and they charge an arm and a leg for it. Bearing have a far superior power system and just a handful of solar on the roof which does not by any means define the design. The sound of water you hear gnashing against the hull is indicative of the poor build quality and materials of this vessel. If these RUclipsrs would only tell you what they really think, they would never recommend this boat based on the build quality alone
Uhm this boat has Solar and a generator(Like all Silent Yachts, also this boat is from 2016)
Wind power creates noise(Watch The O'Kelly's video on it for more info)
How would you do HEP on a moving vessel without increasing drag(more drag means more energy usage to keep the same speed

Slow down. You're talking too fast. 🙂
