1. A human-powered watercraft comprising:
a frame; a forward hydrofoil attached to the frame; a first rear hydrofoil attached to a first strut, 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; a second rear hydrofoil attached to a second strut, the second strut rotatably attached to the frame at the pivot point and parallel to the first strut, 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 to enable the first strut and the second strut to move in a generally stair-stepping manner rotatably pivoting about the pivot point which causes the first rear hydrofoil and the second rear hydrofoil to propel the human-powered watercraft forward. |
