Human-powered hydrofoil

Means of propulsion include screw propellers, as in hydrocycles; aircraft propellers, as in the Decavitator; paddles, as in a Flyak; oars, as in the Yale hydrofoil sculling project;{{cite web

Flapping wing propulsion devices are hydrofoils that produce propulsion by forcing a foil to move up and down in the water. The forward motion of the foil then generates lift as in other hydrofoils. A common design consists of a large foil at the stern that is used both for propulsion and keeping the passenger above the water, connected to a smaller foil at the bow used for steering and longitudinal stability. Riders operate the vehicle by bouncing up and down on a small platform at the stern, whilst holding onto a steering column.

It is started and landed from the shore, or preferably from a dock, and requires a bit of experience. When moving too slowly, it will sink, and the range of possible speeds is {{convert|9|-|30|km/h|mph kn|abbr=on}}.

Several variations on the design have been developed:

• The Wasserläufer was a forerunner of the design developed in Germany during the 1950s.{{cite web
