摘要： A watercraft includes a towing bar that allows the tow line connection point to move with respect to the watercraft. This movement of the point of force application reduces moments created on the watercraft resulting in pitch, yaw, and roll. The towing bar can be formed as an inverted V-shape. The towing bar can also be formed as a flexible beam that bends in the lateral direction of the object being towed. The watercraft may also include a pylon that can be moved between an operative position and a stowed position. The pylon is selectively supported on one of two longitudinally and vertically displaced mounts and at an upper lateral support member formed by the grab handle.
