Human-powered hydrofoil

A human-powered hydrofoil is a small hydrofoil boat propelled entirely by the muscle power of its operator. A typical design for human powered hydrofoils consists of a large hydrofoil at the stern end that is used both for propulsion and keeping the vehicle above the water, connected to a smaller foil at the bow used for steering. Riders operate the vehicle by bouncing up and down on a small platform at the stern, whilst holding onto a steering column. [cite web
