The "Flyak" - a kayak that "flies" on hydrofoils

Hydrofoils are like underwater wings that can lift the hull of a boat above the water and thereby markedly reduce frictional resistance to forward motion. The still image above shows how they can be attached to a kayak; beneath that is a video showing the remarkable speed that can be achieved with such a setup.

This is not a diversion for the weekend enthusiast; it obviously requires not only great paddling skill but also superb cardiovascular fitness.

Thanks, Christophe, for the link to the video!
