What a great story these guys have & what an achievement. If this battery technology is truly innovative & groundbreaking I expect either Yanmar or Volvo will own Sialia’s technology very soon and these two entrepreneurs will be mighty rich 🤑
Looks to be an ideal size for weekends/week trips across the Med to Corsica. What would be the range in 'Normal' mode? I am guessing the the variable Genset onboard it might be unlimited (depending on fuel). I am Deeply impressed and I love this new 'going electric' trend. Just to be able to hear you speak at normal level while doing 26 knts is amasing.
I'm hoping to do a LIve Stream interview with them on Friday of this week Patrick, so you'll be able to ask them all the details you wish! I'll announce the day and time on the community tab of this channel.
From an engineering point of view it's difficult to establish the note worth specifications, hence the omission of the all important 'range'. However from a yachting perspective as heavily emphasised in this video it's mostly about quieter cruising. I like that the engineers were aware that this is not 'eco friendly' 👍
What a beautifully crafted yacht. It's perfect for my needs but... This innovation won't ever hit the water until these two engineers put up a solid gold, ironclad warranty.
Excellent interior design. Love it. Hull design so-so. I hope the optional genset can bypass the battery pack if needed. Based on the (limited) drawing I see on the Sialia site this is not the case?
Very nice looking boat. Is there stabilisers? The hull is not big enough to accommodate solar panels so I'm guessing the idea is to charge the batteries with shore power and top up if / when necessary from the onboard generator. It's great to see such innovation, and I'd also like to mention silent yachts, pioneering such technology.
- it is ready for seakeeper, just not installed - we decided not to have solar panels, and have openable one - we can use 22kW from AC or up to 150kW from DC - rex is used to produce power - it can be used for charging batteries, or for propulsion, or for boths. All is connected to the same DC grid on board
Me, Engineer myself, can't see the point. technical yes, its an electric driven boat, but if it was so great, they would not have to size the range extender so big, it would drive the vessel by itself. Range extender are designed to let the vehicle (of any kind) go a little further or power subsystems so that the main motor/engine can concentrate its efficiency to accelerate itself. So they have a combustion engine that can power the ship along without the hybrid system. More efficient yes, since and electric motor has less losses and does work at its most efficient state more often ... but that's no news at all.. What I don't get, is why they built a vessel, electric push and huge (industry) batterie with great EMS in mind, but no Solar power whatsoever. It would impress if they did a system that had solar panels on the roof, and a (lets call it) "seakeaper plus" turning the boat on the coordinates to always face the sun, so that the panels can charge the batteries at optimal speeds the whole day. ... I would be astonished if they had invented a super efficient way to use solar panels to charge the batterie while at anker and power it at lets they 5 knots cruising speed. If you need more or just started from shore with a full set, than go faster... Wow would have been so cool. by the way: not polluting the air is an argument, but I think yacht owners that operate their luxury In the fresh and windy sea ... don't care about having "NoX fumes" "around" them... Haven't heard one owner complain about having bad air quality around his 5 Million Dollar/Euro/Pound sea home. As much as I love researching and trying to maximize something with technology and innovation. From what the video tells me about it, I really can't work out, why it took them over ten years, and how this idea is presented as game changing, since their are boats out their having the solar idea used, cars are doing it for around two decades nowadays. From a scientific point of view it's really not that big of a deal. But, and that's important I wish them best of luck in selling this, maybe I'm the odd one out here... and someday, someone will explain the genius behind it.
Yeah i thought the same things for the solar panel. They could have added some on the roof and make it turned automatically with AI technology. Tho if i ever get to the point of buying a yatch, it will be electric!
While i am a proponent of electric drive technology for yachts i think it's folly to think that the public or state electric grid should be used or relied upon. yachts must generate their own power to be ultimately viable and acceptable. the use of ultra-lite but strong and hard wearing new materials will be absolutely necessary rather than the currant marble-leather-metal-fiberglass. of course it all must begin with the foundations of a good and proper boat. a beautiful boat and the right direction, bravo.
Interesting development, that will bring change to the yachting world. I like the idea of this. Spacious looking boat, comfortable looking, high tec looking helm, love the cabin clean looking light and airy. I like her, very much. Is this a boat for you David? I know you're looking for a yacht.
A yacht that anyone can operate but only the 1% can afford. All jokes aside.... I cannot imagine using sure power to recharge that boat so I see owners just using the generator. Still locked to the use of diesel... That being said I have started to see charging points on the docks. I think silent yachts really has the best option.
It is only worth noting that all solar catamarans (of comparable size) have diesel range extenders. If you are looking for something with truly unlimted range, and wiyhout fossilf fules i woudl suggets following options: -MS Tûranor PlanetSolar - th-cam.com/video/eNw6l0H1xwE/w-d-xo.html - sailing yacht
Assuming you could get 300 sq ft of solar that would equal 6000 watts max. The battery on the 59 footer is 1 MWh. That would take 167 hours to charge and then you might get 2 hours of endurance
Any new boat nowadays that doesn't slap solar on otherwise unused roof space seems weird. Doesn't even have to be an electric boat to benefit from a few hundred watts of solar to keep the batteries charged for onboard electronics. You don't have to bend over backwards to optimize for max solar, just use the otherwise completely unused roof space.
The range extender for this boat is 100KW, while at cruise the electric motors use 400kw. Even without the motor running, you are looking at at least 10 hours of charging.
@@chippyjohn1 rex on sialia 57 is 390kW DC continous, and we are looking for up to 45minutes of charging, and ~15 minutes for power that is needed for 24hours at an anchor with AC on
Nice - but the lounge seating has backs that are too low - you have to sit upwards, it doesn't look like a couple could romantically snuggle with such low backs.
800kwh of power, at full speed you will need about 1000 horsepower to move at 26 knots. so 25 miles of range at speed? maybe 75 at displacement speed? yea not a gamechanger at all... unless gamechanger means hopping 15 minutes away to the neighboring marina. i mean your electric dingy will have more range.
Per previous interviews, up to 200nm of range at 8kn, 174 at 18kn, and full recharge from generator in under an hour. 200nm range is with a 1000kwH pack versus the 800. I presume most owners will charge at the dock and probably not ever hit 100+ miles, but it doesn't sound bad at all going from 0-100% in ~45min, you could easily do that while stopped for lunch and only use a couple gallons of diesel.
@@GoodkatNW have you ever seen a yacht of this size move at 18 knots with a 110 horsepower motor? this doesn't pass the smell test. also to recharge a 1000kwh battery with a generator/ you will need about 100 gallons of diesel fuel. 45 minutes for 1 000kwh charge would bean you need 1500kw charger or so. yea i dont see that happening on the docks. the amount of voltage and current that close to the water... no safety board will ever approve it. that's more than 2000 amps at 720 volts :D or near 4000 amps at standard 380 volts :D that's like 10 times the current of a welding machine. they are full of shit. math doesn't track.
@@jstefa2 Just quoting from their interviews and website, and yeah the recharging of full pack in that time period does look super unlikely. What's interesting is that David mentioned a full recharge in 45 minutes, but I don't see that claim on their website. Perhaps a misunderstanding, as their site says "sustained cruising at 16 knots" with the diesel range extender, which entails something like a 20-30kw generator. I was VERY far off with my diesel estimate, for some reason I was thinking of the usual ~20ish kwh generator which typically consumed about 0.5-1.5gal/hour depending on load. With a 1mwh battery though, that's like 50 hours of charge time from the generator alone, lol. They state their motors are 400kW apiece, so 800kW = 1072hp, or 536hp apiece (1kW = ~1.3hp I believe), which does seem reasonable for their claimed performance.
It comes with a 1500 liter fuel tank. I would like to know how much fuel the boat would need for the advertised range claimed by the makers. This is not a fossil free yacht.
I love the look, but electric drive still isn't of much benefit for a boat. The range extender for this boat is only 100KW, while at cruise the electric motors use 400kw. Even without the drive motors running, you are looking at at least 10 hours of charging. A range of 85km on battery is not great, and the fact the generator will not be able to keep up with demand is not great either.

@@tgackoski I see the Rex battery+generator option. That means it is essentially a diesel electric yacht. I see the benefits of having electric drive for in and out of the dock, but after that it is still diesel powered. I understand the design hurtles of electric drive on a yacht of that size. My yacht design is 25m which includes about 18kw of solar with a 130+50kw battery bank. I have matched it with only two 15kw motors for slow maneuvering, as beyond that it becomes inefficient.
WOW! Not only the first, as you said, but truly a game changer! I'm impressed. She is the perfect luxury weekender yacht. Thanks David!

Wow, the yacht is a beautiful combination of advanced technology and design. I wish these two all the best with their new company.
This is the technology that many people have been looking and waiting for. Safe battery management, in my honest opinion, is absolutely key as well. 👍

Some quick math. 2 x 400kw motors running at 75% will give you a whopping 1.7 hour endurance. Hmm. That’s with a massive 1MWh battery!!
Add solar power maybe? 🤔
New tech has to start somewhere. Remember floppy discs?
Wow amazing, what a great life with such cool yacht; which shipyard was able to build such a masterpiece?
