Abstract
A watercraft is disclosed including an improved ride plate for enhanced handling, responsiveness and performance of the watercraft. The ride plate preferably has two grooves formed in the undersurface of the ride plate. The grooves are of continuous cross section, extend the entire length of the ride plate and are located behind the water intake duct opening. Finally, the grooves are strategically located to avoid the turbulent water caused by the water entering the water intake opening so as to increase the handling, responsiveness and performance of the watercraft.
