Pneumatic Boat Ski

摘要

A ski structure for increasing the performance of the vessel is intrinsic to or attached to the hull of the vessel. The ski structure includes a bow portion, a stern portion, an amidships portion, plurality of first sidewalls extending downwards to form one or more upside-down U-channel(s) along the length of the vessel hull and situated to provide balanced support across the width of the vessel. The bow portion includes a rear flap for allowing the entrance of water into the channel and prevents the escape of gas out of the channel(s). The stern portion includes a rear flap for preventing gas from escaping out of the stern portion. An inlet port on the amidships portion and in front of the rear flap for injecting a gas bubble beneath the vessel into the channel and pushing the gas bubble below the waterline and thus resulting in producing lift and effectively eliminating any solid surface part of the vessel hull from being below the water line.

1. A ski structure attached to hull of the vessel, said ski structure for increasing the performance of the vessel, said ski structure comprising:
a bow portion; a stern portion; an amidships portion; and plurality of first sidewalls to form an upside down U channel along said bow portion, stern portion and said amidships portion; wherein said bow portion a front flap for allowing the entering of water while preventing the escape of gas from said upside down U channel; said stern portion having a rear flap, said rear flap for preventing gas from escaping out of said stern portion by maintaining a seal to trap gas within said channel; said plurality of first sidewalls extending downwards from said amidships portion to form a seal with the sides of said front flap and said rear flap to trap vapor at an operating pressure; and said amidships portion having an inlet port in front of said rear flap for injecting a gas bubble beneath the vessel into said channel and pushing the gas bubble below the waterline, thus resulting in producing lift and decreasing the weight of the vessel acting on the water surface.
