What a beautiful boat. This would also make a wonderful tender. Love the anchor system as well. Everything is clean, functional, modern and purposeful.
With 150ke I'll feel more in harmony with nature with a 10m sail boat, where I can have also a alcholic dinner and beautifull moment in bedroom with my wife... ah and I can face the sea instead of a very borning lake
Making boats like that electric is really good bcs nobody can complain of range or anything and batteries can be really big and you don’t go on trips around the globe with that. Thats just lake boating and i think its perfect.
Awesome. It has a modern streamline look along with a classic style of the early high end boats. That's my initial thought on it. It looks totally bad ass by the way haha
How many years (or cycles of charge) are batteries expected to last? How much does it cost a replacment battery? Since battery performances depend on temperature or humidity what is the range supposed to be by its design with a safty margin? Why no back-up engine (or generator) is provided? How much time does it take to recharge the battery pack? I understand sailing sounds so old and wind is not there everyday, but ...
@@cameronrobertson9518, imagine yourself as Robinson Crusoe on unhabitable island. Without solar panel you are totally without electricity. Or in the middle Med with totally flat batteries.
@@eldarkarimov6717 Solar panels are effective for small consumption applications like charging a phone, but when you consider the amount of current that the motor draws it is far more than the solar panel could provide. Additionally, a hardtop and solar panel would likely shorten the boats range as the weight of the add-ons would be greater than the additional range gained with the panel
@@eldarkarimov6717 u can carry solar panel in boat storage...but not a hardtop...its too heavy and increase drag....not worth it..... And also....if u want a full charge with solar panel.....better use that panel to charge ur phone...and call for help!.... I guess it take more than mounth to charge batteries these big....
This is awesome 👏 👏 I like the logic of of this boat it’s actually the first thing humans should do is transfer to electric boats then car not cars first water is important air is still good
what is the maximum speed? what is the distance at top speed till run out of battery? what is the maximum distance it can travel till it run out of battery at eco or efficient speed?
Until they can do something about lithium extraction and in essence create a "better battery" electric will never overtake combustion, but its neat to see it getting closer and closer
Solid oxide fuel cells are a promising alternative to batteries for electric vehicles. They can achieve an efficiency of over 60% and can run on hydrogen or light alkanes like methane.
@@brianpreston8483 I highly doubt it's worse than mining for oil since the lithium in the battery is not a consumable and can be recycled. With oil, once you burn it you need to mine new oil.
@@brianpreston8483 That is not an argument, looks more like an ad hominem than anything. Research about what? The energy required to mine lithium? Or the dead wildlife caused by spillage of lithium brine? There are a lot of problems with mining lithium and it's even worse with cobalt, which is more rare and toxic. However it's still it's no where near as polluting as petroleum. That's one of the reasons I think that in the correct way forward is a combination of fuel cells and batteries.
would it be correct to say, that since this engine is rated for 125kW, and if it was run at max power, for one hour, it IS 125kW per hour? and what do typical diesel boats like this "usually" run at 70% or when pulling a skiier? is that 95% usually? I truly don't know.
Yes it does. The shaft is already spinning. Id suspect on some kind of frequency drive. The generator can be in line with main shaft. Thus whenever the main shaft is spinning. The inline generator. Will use wasted energy from the shaft. With a true soft start. Autotransition between the batteries could be smooth and undetected. Accept by gauge or meter. Sorry gotta go to work now,cheers.
If just 1 foot of the shaft was iron cored. This would be a rotor. If a copper winding (mounted stationary) was wound around the shaft/drive live. It would generate a back EMF. As the drive spins. This could rectified and used to charge the batteries. You got me on the weight;but,this is still has utility. Imagine your out on the water. Batteries are running low. You could flip a switch. And charge while you drive. Just a concept. I doubt there is a battery that can perform to these types of loads.
beautiful boat! Love the electric engine! Maybe the batteries will someday reach the level of efficiency to truly compete with fossil fuel propulsion. Soon I hope
vachief efficiency is ratio of output to input, electric motors are in 90% eff where gas motors are 40%. Your example of 24 hour scenario is incorrect. You don’t mention how the boat is being operated, if operated 1/2 throttle how many times will you have fill up your boat in a 24 hour period?
M S I referred to the batteries, not the electric engine, fossil fuels are more efficient in supplying copious amounts as energy in weight compared to batteries, making fossil fuel systems more practical. batteryuniversity.com/learn/archive/batteries_against_fossil_fuel
10:00 there is some interesting numbers: EUR 90k for E-boat with: engine 15kW and battery 16kW EUR 340k for E-boat with: engine 150kW and battery 125kW. This is the fast one! 🔋1kW de lithium battery is = EUR 1k
Per me che sono francese, questo doppiaggio in inglese è insostituibile 😬. Spero presto una versione in italiano. Le foto sono molto belle e questa bellissima barca. Nessun pollice blu questa volta ...
This makes me very happy and very sad at the same time. If the hull designers of this boat used the sq.m of the hull to store it's lithium power packs this would have been perfect. Here's some very simple math to explain why this boat is a complete failure. Area of hull that could have been used to store batteries: 19.75m² Area per 75KwH using 21700 lithium cell packs (Tesla model 3): 1.15m² Number of 21700 packs that could fit inside this boat: 17.17 Available power density when using the hull to store the batteries: 1.288 MEGAWATT HOUR What this boat is being sold with: 125 Kilowatt hour Seriously, how did the designers of this boat miss such a golden opportunity? Edit: The price per kilowatt in this boat is absurd! Tesla is only paying $111 per kWh on their 21700 cells. Who the hell is dumb enough to spend %1000 markup on a failed plan?
Electric is great, because the worst thing about motor-boating is the engine noise and exhaust fumes. I can't wait to see more boats powered by Hydrogen Fuel Cell Electric Motors, with compressed gas-tank fill-up taking only minutes, using Hydrogen sourced by splitting H2O by electrolysis powered by Solar & Wind Electricity. H2 is a great energy storage medium for Solar & Wind Electricity. We already have H2 Fuel Cell Cars, Buses and Trains, and boats are next.
I like it, but I feel like if range is reduced I'd rather have a more physical experience, like a light and nimble jet ski with a top speed of 60 km/h and a range of 10km at full throttle. That way you don't carry a lot of batteries and instead can just recharge it after using is for a quick ride.
Yes, some nifty design features. But very little cockpit and usable deck space for such a long boat. Easy to speed on flat water and no wind. Let’s see it perform in choppy, saltwater seas.
Wowww this is being made by high intelligence and design, I have to add of the design it must be had a top down cover to have more comfort and aerodynamic. Then it must have a scope 180 degree camera for advance vision for the route for the safety.
In the future there will be fusion power plants, electric planes and cruise ships, and journalists still confusing kilowatt-hours with kilowatts and kilowatts per hour.
Imagine if it had carbon ion batteries to where the body is a battery and no need for lithium. Check out carbon ion energy systems. They have something like that in the works. They are merging with corporate universe soon. Couv is the ticker
now that's a beautiful boat, but at 7 knots you're using 12.5 Kw/h, and at 10 knots when you're gliding you're using 30 Kw/h? Also, if 1Kw of battery cost 1000 eur, electric car manufacturers would be losing money on each and every car.
Still don't know the top speed and can I spend all day on the lake, water ski, wake board, tubing and not run out of power until 4-5 p.m. like my Mastercraft? It must be nice to be out on an open lake without any engine noise I have to admit but for 340,000 euro's, it's out of my price league. Beautiful boat though!
The only thing I don't like is that they use gas to produce electric vehicals it's counter productive they need to use hydrogen to fule boats longer range than gas and electric and if they had the world runing on hydrogen it would make sence but to make it with gas engines doesn't make a lick of sence there still poluting the same amount to produce the product
The front nose should have been covered not in teak but solar panel to allow trickle charging. Such a wasted opportunity. There is quite a lot that is wrong with this boat. The shape however is the winner
2 to 3 hours of run time... no thanks... we go all day away from any marinas that could even possibly have a recharge station... I mean...how many marinas actually have a recharge station on the dock for a boat
