That looks more like the future of mega yacths when we run out of oil!

As for the original post, that looks like the future of kayaking, not sailing, but hey, if it brings more people into sailing, it's all good. Much rather see a bunch of those on my lake than more Jet Skis.

I'm going out to ride my bike around the lake again, I'll be daydreaming of one of those pedal hydrofoils! That would be nice.
