The hydrofoil board with a prop and motor looks really cool.
Just not sure what the learning curve is like and kind of worried about hitting something and flying off.

Since the original article is about human power, I'll also link to this foil[3] which is for pump foiling long distance. I had run across the channel well before that and thought his goal for a half hour was goofy when people were getting 90s or 2 minutes so I was quite shocked when it actually got built.
I, frankly, don’t understand it. They aren’t particularly advanced devices.
I'd happily buy a well made new one for £3000 if that was what they cost, but half that price is a new good solid paddle board - so I can see why you can't get the same plus all the electronics you need for £3k.
We can hope in time the costs come down, but as a niche sport, it will be some time, if ever. Have you seen the cost (and service intervals!) of a new jet ski? All simple tech, but they don't come cheap and need a lot of looking after.
I can still dream though.
