Aerial characteristics in a wakeboard performance are improved with a vessel having a skeletal frame including starboard and port rigid vertical support structures fitted to opposing sides of the vessel with a horizontal bridging portion extending between the structures for attaching a tow rope. Further, ballast tanks are fitted onboard and only aft amidships of the vessel, at or above the waterline. The ballast tanks are filled with water during movement of the vessel using a water scoop which extracts water from the body of water upon which the vessel operates and forces the water into the ballast tanks during movement of the vessel through the body of water, weighting down the stern, thus lowering the vessel into the body of water and affecting the wake created by the vessel. By controlling the amount of water carried by the tanks, a desirable wake is formed for use by the performer. The weighting is controlled by controlling air venting to the ballast tanks. The tanks are emptied while the vessel is stopped, permitting them to drain.
