摘要： A watercraft having a propulsion mechanism extending through an opening in the bottom of the watercraft having a propulsion mechanism adapted to be inserted in an opening in the bottom of a watercraft comprising a pair of pedals each coupled to a flexible fin extending below the water line, the pair of fins oscillate through an arcuate path on a horizontal axis to propel the watercraft. The horizontal axis is preferably continuously rotatable in either direction through 360° on a vertical axis disposed at a substantially right angle to the longitudinal axis of the watercraft to propel the watercraft in any direction.

摘要： An apparatus for adjusting a human propelled watercraft having a pair of flexible fins extending into the water. The invention allows the user to easily adjust the propulsion device to match the user's leg length. The invention consists of a push button mechanism that converts a vertical motion into a horizontal motion allowing a locking pin to retract and the propulsion device to be adjusted. Once an adjustment position is selected, the user releases the button and a spring reverses the motion of the pin, locking the mechanism into position.

摘要： A watercraft having propulsion means extending below the water line comprising a pair of flexible fins each adapted to oscillate through an arcurate path in a generally transverse direction across the central longitudinal dimension of the watercraft. As input force is applied, the fins twist to form an angle of attack for providing forward thrust while moving in both directions along the arcurate path. Each of the fins have a generally squared off top and preferably an outer area of harder rubber than the inner area. Each of the fins can be adjusted at the trailing edge to provide adjustable tensioning of the trailing edge.
摘要翻译： 具有在水线下方延伸的具有推进装置的船舶包括一对柔性翅片，每个柔性翼片适于在大致横向的方向上跨过船舶的中心纵向尺寸摆动通过弯道。 当施加输入力时，翼片扭转以形成迎角，以沿着沿着两条路径的两个方向移动而提供向前的推力。 每个翅片具有大致平方的顶部，优选地比内部区域更硬的橡胶的外部区域。 每个翼片可以在后缘调整以提供后缘的可调张紧。
