摘要

The boat has a blade (15) put in an active position and moved in a reverse direction when a handle (7) and a tension cable (26) are moved in the reverse direction from a front end towards a rear end of a frame, where the handle and the cable control displacement of the blade. The blade is put in an inactive position and moved in a forward direction when the handle and the cable are moved in the forward direction from the rear end towards the front end of the frame. The blade exerts a thrust force and a minimal resistance force on the water in the active and inactive positions, respectively.
