Abstract
The aerial performance characteristics of a performer using a water sport implement such as a wakeboard, and being towed by a vessel while maintaining stability of the vessel includes a first relatively rigid vertical support fitted to one side of the, a second relatively rigid vertical support fitted structure to an opposing side, and a horizontal bridging portion extending between upper extremities of the first and second vertically extending supports, at a height substantially above a level of the operator station for the vessel. A tow rope is attached to the horizontally extending bridging portion for towing the performer from the horizontally extending bridging portion while operating the vessel in a body of water. By pivotally attaching the first and second supports to the respective sides of the vessel, they can be rotated downwardly so that the vessel may pass underneath a bridge or into a boat house.
