SIALIA - The HIGH PERFORMANCE Electric Yacht! 

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!

I like this one far more than the Windy!

Wow, the yacht is a beautiful combination of advanced technology and design. I wish these two all the best with their new company.

Impressive boat, excellent power system, simple and elegant lines/design, smart space distribution... The future of yatchting has officially arrived...

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. 👍

What a beauty, I mean the yacht David, the new technology offers new choices, it looks such a different experience, which I guess some won't like, but in a few years this will be the norm. Nice video, guys.

So much info there! Great channel

Nice weekend yacht technology may make people run away but we all have to go that way eventually what a fabulous thing she is

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.

Why no mention of range in electric only mode ?

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!!

I a word impressive I have to say I really like this yacht I think I have to say that that boat got on plane quicker than any other boat that size that have ever seen

Extraordinary! Thank you.

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 🤑

Like the concept, and she is really beautiful inside and out 😊

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' 👍

Super exciting!

The silence was loud 😃 Impressive!

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.

I love it. Perfect

Wow what a nice interior!!!! Those people may design my house 😍😍😍

Surprisingly, I really liked this yacht. I'm not always a fan of ekectric boats. The overall design of the yacht is excellent. The interior was superb. Thank you, David.

I was not expecting that Master Cabin!

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?

Awesome!

AWESTRUCKINGLY BEAUTIFUL YACHT 🛥️

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.

What a beautiful yacht. The only thing missing is a solar roof.

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.

Wow amazing, what a great life with such cool yacht; which shipyard was able to build such a masterpiece?

1:04 ...every sailor who just got back back from the "Maxi Yacht Rolex Cup" starts scratching his/her head... PS: Interesting video!

Hope it has a good fire suppression system.

Nice one indeed, I wonder how much the range is on those batteries 🔋

I understand range varies with temp and sea state, but it would be useful understand your expectations for cost and range??

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.

The colors make it look like some kind of Ferry

It seems expressive. What was her range?

Amazing boat, the only not so good thing that could be improved is the driving visibility wile seated, the rest…. Spectacular!

Great looking yacht! Could you replace the sunroof / skyroof with a nice bank of solar panels to recharge the batteries?

No mention of the range on the batteries before you have to spin up the generator?

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.

But what’s the range? That’s the key issue with any electric boat or car.

I'll take two.

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.

Hi,what is the range?

Who is the designer David? He/she did a great job!

How much is it?

I would like to know the range

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.

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.

IMO when it comes to EVs, the presence and efficiency of range extenders are the difference between success and failure.

Better looking and more functional than a Pardo! Fight me.

Jezesnjevc lejga, mora da radi na struju

wowww, " it even has a coolbox " whahahahahaa

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.

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.

If Apple made a yacht

ONLY 200000 US

No Sea Keeper…. Shame

Remarkable ship.
