Claims19
A boat or ship hull having at least one ventilating propulsion tunnel formed therein open to the water;
- said tunnel having a leading edge forward of the hull's transom and being adapted to contain a propeller of the propulsion system, said hull including an interceptor plate projecting therefrom at said leading edge downwardly from the hull.
A watercraft vessel comprising a hull having at least one ventilated propulsion tunnel formed therein opening downwardly to the water surface when the hull is on the water, said tunnel having a leading edge located rearwardly of the LCG of the vessel;
- a surface operating propeller partially enclosed in the tunnel for partial immersion in the water, and an interceptor plate mounted on said tunnel at the leading edge of the tunnel to project a predetermined distance downwardly from the hull.
