    • A pedal operated catamaran includes a pair of side-by-side buoyant hulls, and a rigid frame releasably mounted to the hulls in one of two alternative positions, to maintain the hulls parallel to one another. The catamaran includes a propeller mounted for rotation with an elongated, longitudinal propeller drive shaft. A gear train drivably associates the propeller drive shaft and a crankshaft, for propeller rotation responsive to rotation of the crankshaft. The propeller drive shaft further is pivotally mounted to allow selective alternative latching of the propeller in a retracted position and in one of several operating positions, as controlled by a hand-operated lever. The latching mechanism allows on-the-fly adjustment of the propeller position. In the retracted position, the propeller is automatically angularly locked above the hulls, to facilitate car top carrying of the craft without disassembly.
    • 踏板操作的双体船包括一对并排浮力船体,以及刚性框架,其可拆卸地安装在两个替代位置之一的船体上,以保持船体彼此平行。 双体船包括螺旋桨,其安装成与细长的纵向螺旋桨传动轴一起旋转。 齿轮系可驱动地将螺旋桨驱动轴和曲轴相关联,用于响应于曲轴的旋转的螺旋桨旋转。 螺旋桨驱动轴进一步枢转地安装,以允许螺旋桨在缩回位置和由手动操作杆控制的多个操作位置中的一个中选择性地替换。 闩锁机构允许螺旋桨位置的即时调节。 在缩回位置,螺旋桨自动地角度地锁定在船体上方,以方便车顶运送而不拆卸。
