In Croatia, I had the opportunity to ride on a couple of electric boats inside the Plitvice lakes. It really changes the experience since they are so quiet that you only hear nature.
Consumption at 27 knots is close to 6 KWh /nautical mile which is a range of only 20nmi / 37km... Drive it like you are meant to drive a Goldfish or any other power RIB and that range is likely cut in half... This is why traditional planing hulls on electric boats is not really feasible yet. At least not without even bigger batteries and proper fast charging.
With a propeller and hull that still is not optimized, we have seen stable 4,5 kWh/Nm in 40 knots. And we will optimize more. 25 - 30 nm in the range is good enough for many, but not everyone.
They can further their mileage by reshaping the hull such hydro foil. Or use hybrid design , sails + motor, Some naval engineers have designed sails that is controled by computorized, so boat driver need not to have knwledge in sails navigate.
@@swecreations When? From 5:30 to 5:40 and from 7:40 - 7:50 it's shows a steady 5,5 - 5,6kwh/nm at 24-25 knots... You must have looked when he trottled back for a fraction of a second.
Range and charging infrastructure is of course one thing, but the bigger picture here is how sustainable it is to currently fill a recreational boat like this with huge and valuable battery packs when we know the average use per year is only 30-35 hours(!) So much natural resources and energy just laying there unused for 99.9% of the time. On the other hand, recreational boating is the definition of unsustainable in the first place, but for now, this isn't really helping IMO... Professional users on the other hand, that is a different story.
The goldfish boat is a plattform with Evoy electric drivetrain. So Evoy drivetrain maybe can be used on other hulls. There is a company gong to make electric foiling ferrys to Singapore/Malaysia i gess it is. I can see if i can find it in the interwebb. But agree. Get back this hydrofoils. We had some passanger boats in the 1960 - 70. I dont know why we stopped.
I just love that we are getting electric boats as well! When these fast boats (soon) prove to be cost effective, there will be supply issues for å while. I am more of a displacement hull kind of guy. 18-21 ft (6-7 m) @ 5 knots Solar panel roof could probably be enough
A lot less noise from shore :) But you can still hear the mechanical Stern Drive on this boat. Evoy connects to shaft too, there the noise is almost gone.
A goldfish rib has a extremely efficient hull with “triple steps” and very little hydrodynamic drag compared to most boats. And a big powerboat is pretty useless design for most people.. the X9 is a sub military boat that isn’t really that practical either I guess, but it’s a good platform for testing out new propulsions.
I'm sceptical of the efficiency remark - more efficient at 40kn than 25kn - The water and air resistance will be far far higher at those higher speeds. If this was a hydrofoil then that would be different but it isn't; not sure why its not a hydrofoil, perhaps as it takes more hull space and this is a rib.
@@tommaso660 You can optimise the motor and the boat to a certain extent but without a hydrofoil significantly reducing the water resistance they can't cheat the air and water resistance, especially the former; there's a massive difference, as I pointed out, between those two speeds which far outweighs any motor optimisation. At both those speeds the boat will already be on the plane taking advantage of hydrodynamic lift. Until I see 3rd party data to support that claim I won't believe it.
@@andrewallen9918 Hi! YOu can see on the video that we have about 5,5 kWh/nm in 25 knots and we have about 4,5 kWh/nm in 40 knots with this prop. Both can be optimized further. The reason that the consumption goes down is that the prop still doesn't have a propper grip at 25, and is therefore inefficient at this speed. Also, this hull has 4 steps in the hull. For this boat that means that she has about the same consumption pr distance sailed in 30 knots as 40 knots. Follow Evoy here on YT and we can show you in films coming up.
@@mrheavymetalll Thank you for the explanation. I could not see the stepped hull in the video. I recall that it was mentioned in the video that there were issues with some of the figures displayed on that chart plotter screen as it was not a finished product yet; I look forward to further updates.
Støy er ikkje problem i ein moderne firetakter. I 30knop med min 15 år gamle firetakter er det ingen problem å ha ein samtale. Det er vinden som lager mest støy. Bjørn, du kan godt være med ein tur i min båt, men da må du snakke Norsk.
Do some reading mate. HFC cars are actually evs with their small battery charged by the fuel cell. The fuel cell cannot provide the instantaneous current needed for acceleration. These are complex cars with the tiny drive battery being constantly thrashed, with deep discharge. The drive battery will probably only last 100k kms. Then the fuel cell membrane will likely also need replacing in 100k kms and the other additional maintence required that pure evs do not have. A HFC car will be expensive to maintain, and likely be a throw away after 100k kms. In addtion, 3-5x more renewable electricity needs to be generated to provide the same power at the wheels for a HCF car than is needed to provide the same power at the wheels for a pure ev. And packaging is also an issue for HFC cars - all those systems need to go somewhere in the car. Then there is the infrastructure issue.

Wind noise, cant hear in high wind.

The 1000 km challenge is going to be interesting
40kn is 72km/h and 60 is 108! 👍
A boat cruising at 70km/h is very fast!
74 and 111
Thank you :)

I multiplied by 1.8 before, and it's 1,852... 😁
With a sailboat we cruise at 10 sometimes and it feels fast

It did 5 kwh/nm at 40 knots in the video, did you not watch the entire video?

For that much peak power they should try foiling boats and get even more efficiency at cruising speed.

Foils are great but will increase price dramatically
Candela does that.
@@arnekvinge6073 Evoy propulsion system can be used on all types of hulls, also foiling :)
@@robertkirchner7981 Candela is great.. but those price are much more than what I am willing to spend on a small boat.
The faster it goes, the more efficient it becomes... That's what we like 😎 😅
Nice to see Bjorn checking out other e propulsion systems, maybe motorbikes in the summer
he already did one last year with their electric scooter in Thailand :D
Great to see, being a rib owner which I’ve been conflicted about because of the 2 stroke outboard and the pollution it is responsible for.
I just love that we are getting electric boats as well!

18-21 ft (6-7 m) @ 5 knots
Solar panel roof could probably be enough
Would be interesting to see the efficiency of a catamaran version in comparison. Good video! ,👍
„Coast guard, suspicious boat loaded with banana boxes spotted“
More progress in the move towards electrification is always good to see. 👍👍
I think speed limits in London are mainly about noise from the engines. So would be interesting to hear it from the shoreline.
A lot less noise from shore :) But you can still hear the mechanical Stern Drive on this boat. Evoy connects to shaft too, there the noise is almost gone.
Holy macaroni: 60+knots is fast! Great video, thanks! 🙂
I think the banana boxes would blow away.
Yep... At 0 knots 50 boxes stacked. At 50 knots 0 boxes 😂
SpaceX need this boat for the recovery dragon fleet!!!!!
Hehe, maybe Elon wants to purchase a fleet of these!
Great to see electric boats nice and quiet with no pollution. As in a car the very wet conditions will reduce range :D
Bjorn, an EB review is awesome.
More of such product reviews please.
50 knots is insane!
Oh yeah! And there is more in there.
How much cargo can this silent powerboat carry? (Asking for a friend in South Florida.)
😎🤑🚤🚁🛩️🚓👮🚓👮🚓👮
Very good 😆
Have been waiting for such a video! 👌🏻

Wow, impressive performance. Electric boats have a future!
Thank you :)
Looks like a ton of fun!
Speed boat sound doesn't come from engine but wind and wave.
Bjorn had full pants hehe ;)
Would electric hydrofoil be more efficient?
Yes, Evoy can do that for those that want that.
Only one thing to say: Cool.
How is it possible for sterndrive to hold that kind off power?
Ballpark price?
Nice boat!
Thank you!
Awesome boat.love it
Great video! I got a bit seasick…!
Very cool , its the future , new wave! No pun intended!
Good job! Really good!
A more aerodynamic form would be better, so the boat wont lift up at higher speed. there is speedboats that go like 300km/h on water

Better to use synthetic E-fuels for boats until the energy density of batteries gets much much better.
50kts is fooking fast!

If this was a hydrofoil then that would be different but it isn't; not sure why its not a hydrofoil, perhaps as it takes more hull space and this is a rib.
you can optimize everything to work at high efficiency at a certain speed, like boat body, motor torque and power etc

Yeah, a fish farm without diesel sprayed on it.
Is it water jet or propellers?
Sterndrive /Z-Drive on this one. Mercruiser Bravo 1.
What is this boat for?
Just to prove that electric boats work or Is it designed to pull or push loads?
Mainly used for A to B and watersports today.
Banana box test?
Inshore rescue boat ?
Fast, doesn't mind not being used between jobs.
Did Marcusbil buy it? =)
Not Yet! :)
Noice !!
If it doesn't have a frunk, it's shiiiiieeeet :-D
sorry but i want to be able to get back home after a days fishing
