Human Powered Hydrofoil

This looks very interesting – I wonder how well it really works. Has anybody tried one or seen somebody using one? It reminds me of a Trikke for water. Dianne and I got the Trikke and it works well once you get the hang of it. It’s a good, low impact cardio workout. I should clarify it’s low impact unless you take a spill and then the impact is high. In that respect the hydrofoil would be nice.
