Foiling is all the rage in dinghy sailing at the moment. Google "international moth foiling"
The real advantage is getting the bouyant part of the hull with all its wave making drag and skin friction out of the water to reduce your drag and this accelerates the vessel. These bikes seem to sit too low in the water to take advantage of that (they leave a reasonable size wake behind them). Its interesting that they only show them on a smooth surface, they seem to have a "sensor" in front them but the big trick is getting a foiling boat to "contour" over larger waves.
They are using carbon fibre to reduce weight - every extra gramme means a bigger foil.
Once again, technology answers a question nobody asked.
Looks like it sinks when you stop pedaling. That's a problem. It also is made from carbon fiber. It should be polyethylene like most kayaks...no need to get space age on a toy, or ruin the whole thing if you hit a hidden rock or log underwater. I'd bet the price will be around $10k if it is anything like the models in the video.
So I have to ask...why this over a pedal drive kayak?
For a normal displacement hull like a kayak, the speed is limited by its length. To be able to travel at the claimed 20 km/h, your pedal drive kayak would need to be about 17m long.
Using a hydrofoil breaks out of these rules, so it can be faster for the same size vessel.
Edit to add- world record in a kayak over 5km is just over 16km/h, but using a very pointy and unstable boat to beat its bow wave.
"We’re busy putting together the final touches needed to enhance the ride experience"
The cynic in me reads this as "at the moment it handles like a giraffe on ice"!
I wonder how big the market for these can be?
now Mark Beaumont has no excuses for skipping bits of his global circumnavigation
Indeed - round you go again Mr Beaumont, what a slouch!
