That's a fantastic machine, will you make a Weekender with a cuddy cabin for two and a toilet? Maybe some solar panels or a small generator to make it a touring boat.
Thanks for posting a video without the terrible music. Any pricing and availability in Canada? Also are the hydrofoils retractable and could you please post a video of launching and recovery at a “standard” boat launch?
@@CandelaSpeedBoat I know they are “spendy!” I would like to know whether the foils are retractable, and would like to see the boat being launched and recovered by a normal person with a pickup truck and a boat trailer!
Great video! 👍 Love that boat. Is there a sonar which checks for potential obstacles under the surface so the foils could retract or adjust automatically to avoid damages? Maybe with an alarm or something to warn the driver beforehand so it would be possible to change the direction?
We have a sonar option, but no alarm. When foiling, the draft is about 3 feet - ssimilar to a conventional outboard craft. Also, we provide detailed sea charts on the User interface.
I wonder if they could use a much larger battery if the increased the foil size slightly. Or perhaps the width of the boat is the maximum practical width of the foils. Maybe they could add more foils.
Not many DuGong that afar north, but I would imagine that that speed impact wouldn't be good for any kind of engine or foil and would probably kill anything in the water.
@@CandelaSpeedBoat staying tuned for more videos of real-world performance. Launching / recovering boat, boat with passengers and gear, load limits, heavy weather operation. If you lend me a boat for testing and making videos, I’d be out on the water every day with it! Promise!
What an amazing set of technologies you've brought together! What is the weight of the batteries and the gross weight of the boat? Why did you settle on having a 40 kWh battery? Any plans to go with a higher capacity battery?
in the other vid shot on lake Wörthersee the guy mentioned a "100KW" battery... not sure if he got it wrong and meant to say KWh : / I'm also intereted what charge the system can handle (that cable on the type2 connector sure was tiny). We are litteraly standing in the shoulders of the car world who have already worked these things out in the past years. CCS for a quick top-up at the local marina?! (I'm thinking of coastal areas not so much lakes)
Thanks! Battery size is always a question of tradeoff between passenger capacity and range. 40 kWh is sweetspot, you can take off with 7 adults and cargo and still get a good range of 50 nautical miles.
The 60 kW motor should be able to go way faster than the 30 knots top speed right? The motor is not the limitation? Is it the hydrofoil? Are you planning on increasing top speed in the future?
but why? energy consumption and wear and tear on the foils would exponentially increase. 30knts sounds pretty good to me. More importantly the relative quiet you (and thousands of other people) get to enjoy while you're doing your boat ride. I find noise pollution (and boat owners disregard for it) among the most problematic aspects with traditional powerboats.
@@velotill as far as I've understood the speed does not increase energy use that much when foiling. The reason energy increases at 30 knots compared to 20 knots is because the design of the foil is made for 20 knots. I might be wrong though
There was a mention of the foils when reaching its 'velocity max' speed wise, which in this case was 28 knts. Trying to go faster than 28 knots exceeds the flow of wing/foil design, creating a turbulent flow behind the foil which increases drag. Also hear the 'boiling water' sound, which is air bubbles created by the turbulence which in turn can affect the generated lift by the foils. Notice how the amount of power required to just go only 2 knots faster than the Vmax, was 150% of the power required to maintain Vmax speed. Just like a combustion engine, you are burning up much more energy for little return/benefit. So really, the theory of a bigger motor being able to make the boat go faster is like 'chasing one's own tail'. You think you see it, however you will never get there, try as you might. The design principle of foils/wings is that, what speed is required to perform takeoff, is half of the maximum speed of the wingfoil shape. Want to go 50 knots speed, sure no problem. It's going to take a lot of push powerwise to get to the takeoff speed of 25 knots, to go foilborne in reaching 50 knots. Speed is nice, yet you do have to come to a stop at some point. Boats don't have the braking ability of land vehicles.
Yes, we have limited the top speed electronically to 30 knots. The foil is designed for being efficient in the 20-25 knots speed range, with a smaller foil you could go for higher speed. But cruising silently in 23 knots without any slamming is probably the best experience you can have at sea!
@@powderkings1411 When the foils retract, it looks like the motor will be left pointing up at a 45 degree angle or worse, and then how will the steering and controls work effectively?
@@CandelaSpeedBoat I agree this is a step forward in engineering and design, I’m just pointing out that it needs to kept in water of sufficient depth bc the possibility of having a sudden stop by hitting a submerged object or the bottom could be disastrous to all on board.
Wow... I was very impressed. Hydro foils did the trick. This is it. You combined electric with hydro foils. Why didn't I think of that? Now lets try it with electric jet drives. What do you think? Let me calculate the power needed for a larger vessel. I will get back with you on that.
Would a jet drive raise efficiency in any way? I feel that the jetdrive having to suck in water would create more drag than a regular propeller that can be driven while the hull is above the water.
There seems to be a major problem, the boat is not able to run, track straight. It never stops turning or banking. Is it a control system issue or inexperience skipper. Lol, if it attacks strait and true I’d love to see it. Also the title “Virtual Test Drive” but it’s an actual, physical test drive, nothing virtual about it!
The Finnjet with gasturbine, was the fastest ferry in the world with 33.5 knots max speed (1800 passengers). This electric boat is boring and not so fast. But congrats for your project.
Nice ... But ... Put 5 people on board ... and pull a skier .... Or at least a tube or something ... Never mentions any sonar for water depth ..WHATS THE minimum depth of water that's safe to travel ... What's cost repair of hitting something with a foil .. Because that's going to happen ALLOT !

@@CandelaSpeedBoat Awesome! Please could you provide a link to the solar option? Cannot somehow find it on your website
It was very cool. Thanks for the ride. 🙂
Wow, awesome 👍🏻
Amazing, what is the maximum chop height you can handle?
About 4 feet without touching the waves at all, but you can always slow down.
1% battery for 1min of driving as you did it at least... so with gentle driving how long can you approximately go?
I searched on the Denison website. Candela is not listed.
You wouldn't hear the squeaking in an ICE powered boat. Nice problem to have.
I wonder if they could use a much larger battery if the increased the foil size slightly. Or perhaps the width of the boat is the maximum practical width of the foils. Maybe they could add more foils.
Low low maintenance! Describing the helm should have includes the camera viewing it. When are these coming to America?
No wake, no emissions!
What’s it like in rough seas? Seems like this would only work on smooth lake waters.
Marvelous ! Nice !
Tour the motor and batteries.
What's the damage to the foils when you hit a dugong?
Not many DuGong that afar north, but I would imagine that that speed impact wouldn't be good for any kind of engine or foil and would probably kill anything in the water.
I would like to see the battery and electronics compartment.
Please show the display when describing it.
What kind of actuator deploys the front hydrofoil?
Electric motors for retracting it, hydraulic actuators for moving it during foiling.
Would it be possible to fit a smaller foil for more efficiency at high speed? Like a high performance foil meant to be only used at 25+ knots?
Yes - but we're not offering that at the moment.
But what's the numbers like with a full load?
Not terribly different! As long as you can get up ln the foils, the consumption isn't too affected - but stay tuned for actual data.

Like a boat. lol

No pounding through the waves.
Display the storage bins and motor.
Can you replace the foils with taller foils depending on the weather or wave height? Like changing your tires depending on the weather.
I agree! The foils need to be longer if you want to drive during very windy days or on the open sea with higher waves.
What kind of aluminum. High nickel alloy to resist corrosion?
100% carbon fiber, both hull and deck. The hull and deck - not including electronics, batteries etc - are about 500 pounds.

Lovely. but if you hit a rock with those foils, you are done, so safe deep water only. Apart from that- Amazing
I wouldn't say he SAVED € 10 000. It's not like the Candela is free...

What is the shallowest draft with foiling and without?
When foiling, draft is about 0,4 meters. In shallow mode with retracted foils, the draft is 0,7 meters.
That's actually pretty good all things considered. Thanks for the reply.
