A system for increasing the buoyancy of a boat operating in the water and to reduce the wetted-surface-friction of the water against the hull of the boat. The system includes a multiple of strakes attached to the bottom side of the boat. The strakes are instrumental in creating a multitude of bubbles on which the hull of the boat will ride which increases the efficiency of the power of the motor or motors powering the boat. The strakes are arranged in series along the hull of the boat and can increase in size from the bow of the boat to the stern. The strakes are also increasing in depth from the bow of the boat to the stern. The strakes may be attached to the boat as a retro-fit or may be added when manufacturing the boat.
A system to increase the buoyancy of a boat, said system includes a series of longitudinal strakes attached to a hull of said boat, said strakes being slanted and canted relative to said hull of said boat to thereby create bubbles as said boat moves through the water, said bubbles create said buoyancy and reduce friction of the water against said hull of said boat.
