As a kid I saw a diagram of a human-powered hydrofoil and since then, I’ve always considered it a mythical creature lurking somewhere just out of reach… the wait is over.

Once you’ve left shore, you need to start bouncing frantically. The knack, however, is rhythm rather than power: if you lose your rhythm, you dive underwater faster than a German U-Boat dodging the RAF. Link

  1. it looks like the frame flexes when you push down so the fins change deflection, like one of those scooters you swerve left and right to move forward, but rotated 90 degrees so its up and down instead of left and right

  2. A remarkably similar flapping-foil human-powered hydrofoil device was manufactured by a Scandanavian company nearly a decade ago as the Trampofoil. They stopped making them several years back. Now this year the “Pumpabike” has been popping up in SkyMall and Sharper Image catalogs. You think they would at least add enough bouyancy to keep the thing from sinking like a stone when you stop jumping.
