Abstract
Abstract A watersled towed behind a moving boat is steerable from side to side by a rider pulling on or releasing the handle on a single control rope which is attached to a tow rope. The handle is held at various positions by two cleats connected to a raised section of the top deck of the sled between the rider's legs to facilitate proper operation of the sled. The tow rope is attached to the rear of the sled by being passed through an opening in the hull and knotted. The tow rope is held in proximity to the bottom of the sled by passing the rope through a plastic slide configured to travel within a groove extending the width of the sled. The groove is shaped in an arc having a center at the tow rope attachment point and has end closures to prevent the slide from leaving the groove. The control rope is held forward of the tow rope attachment point by a knot in the tow rope. Asymetrical trim tabs are attached to the stern by hinges and are adjustable to vary the amount of lift astern to account for different rider weights. The sled is fabricated with spongy foam exterior surfaces on rigid stringers to reduce injuries to the rider.
