Abstract
A water vehicle includes at least first and second foils which are at least partially submersible in water. These foils are movable, at least to a limited extent relative to each other. Repeated movement of the foils generates a propelling force that will move the water vehicle on the body of water.
Claims21
A water vehicle comprising:
- a leading first foil and a trailing second foil;
- a support for said first and second foils, said first and second foils being at least partially submerged in water during operation of said water vehicle;
- and
- means securing said first and second foils to said support for movement in the water relative to each other, said movement of said first and second foils in the water relative to each other generating a thrust force for propelling said water vehicle through the water and a lifting force for supporting said water vehicle in the water.

A water vehicle comprising:
- a support structure
- first and second foils supported by said support structure for at least partial submersion in water;
- steering means for controlling the direction of movement of said water vehicle;
- and
- means for moving said first foil while submerged in the water, relative to said support structure to generate a thrust force for moving said water vehicle through the water and to generate a lifting force for supporting said water vehicle in the water.
2 more elements
A method of propelling a water vehicle through the water including:
- providing a water vehicle having at least first and second foils;
- at least partially submerging said at least first and second foils in a body of water;
- repeatedly varying the inclination of each of said at least first and second foils while in the body of water;
- and
- generating a thrust force for propelling said water vehicle and a lifting force for supporting said water vehicle by said repeated varying of said inclination of each of said at least first and second foils.
