Abstract
A human-powered watercraft may include a frame, a forward hydrofoil attached to the frame, and a first rear hydrofoil attached to a first strut with the first strut rotatably attached to the frame at a pivot point and the first rear hydrofoil configured to pivot about a rear end of the first strut. The human-powered watercraft may also include a second rear hydrofoil attached to a second strut with the second strut rotatably attached to the frame at the pivot point and parallel to the first strut and the second rear hydrofoil configured to pivot about a rear end of the second strut and a tension system coupled between the first strut and the second strut. The tension system allows the first strut and second strut to move in a generally stair-stepping manner which causes the first rear hydrofoil and the second rear hydrofoil to propel the human-powered watercraft forward.
