Abstract
An innertube accessory that facilitates towing an innertube by a boat. The accessory includes a shell for receiving any size innertube and attaching it. The accessory is suitable for being towed by the boat, by a track and trolley mechanism that adapts to different towing angles away from the boat center line. The innertube rider can steer the accessory by operating a rudder. The rudder is a steering rope that controls pivoting of a rudder fin relative to the shell. Additional fins provide stability.
