    • A device including propulsion means extending below the water line comprising a pair of flexible fins each adapted to oscillate through an arcuate path in a generally transverse direction with respect to the central longitudinal dimension of said watercraft, and means operatively associated with said propulsion means for applying input force to said propulsion means whereby as input force is applied said flexible fins can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft while moving in both directions along said arcuate path, each said fin being carried at its upper trailing edge by a fixed pivot and at its upper leading edge by a retainer which is normally engaged while being disengageable when said leading edge strikes a resistance element allowing said fin to pivot aft to clear the resistance element and re-engageable as the fin rotates forward and resumes producing thrust.
    • 一种人造推进的船只,其具有延伸到水中的一对柔性翼片,每个柔性翼片适于相对于所述船只的中心纵向尺寸在大致横向的方向上振动通过弧形路径。 踏板被设置用于施加输入力,由此当施加输入力时,柔性翼片可以扭转以形成迎角,以相对于船只的纵向尺寸提供沿着弓形路径沿两个方向移动的向前推力。 用户可以拉动一个杠杆并使翅片旋转180°并产生相反方向的推力。 如果与浸没的物体发生碰撞,则翅片能够枢转和向后摆动,以避免损坏。 翅片更高效,耐用,可调。 简单的塑料滚子轴承已经适应于减少机械摩擦而不需要油封。
