Abstract: The present invention provides an aquatic towable vehicle that can be maneuvered by the rider to steer the vehicle and to put the vehicle in a controlled spin while being towed behind a boat. The vehicle includes a passenger deck having a convex lower surface, a lowermost center point, and elevated ends. Fins are attached to the convex lower surface spaced out from the center point, and symmetrically disposed with respect to the longitudinal center line of the deck and the center point. The body portions of the fins are elevated above the center point so they are out of the water when the vehicle is level in the water. A tow strap is attached to the convex lower surface at the center point. When the rider's weight is shifted to move the vehicle from the level position, the fins on one side of the center point engage the water and allow the rider to steer.
