Abstract: Boat hull having aerated longitudinal hydrosponsons with air injection into tunnels and distribution to generate bubbles across central running surfaces.

Abstract: A high performance boat hull structure is provided which combines a V-hull bottom portion 12 with mid hull sponsons 31 and 33 which form longitudinal tunnels with adjacent structures. The mid hull sponsons 31 and 33 have horizontally disposed running surfaces to provide lift at high speeds. Outer sponsons 14 and 16 incorporate running surfaces 24 and 26 and together with mid hull sponsons 31 and 33 form a second air tunnel and engage and deflect side directed spray and wake downwardly providing additional lift and decreasing or eliminating spray and signature wake. Entrance of injected or inducted air into the air tunnel area decreases frictional engagement of the hull with water to improve efficiency and ride.

Abstract: The double deadrise with multiple reflex chine boat hull structure and engine mounting system relate to designs for power boat hull structures and engine mounting systems. The hull structure combines the use of two pairs of bottom surfaces, reflex chines and side panels to form a double deadrise hull structure. This design imparts a highly efficient means for dynamic tracking, thereby, preventing "slide-out". The design also enables the hull structure to quickly and easily achieve a plane. The engine mounting device provides an improved means for securing and supporting an engine to a hull structure. The engine mounting device permits the hull structure to have a high transom, reduces the space in the working compartment that would otherwise be occupied by the engine, engine housing, or engine well, permits the proper positioning of the propeller within the water reservoir to achieve optimum thrust performance, provides static flotation and incorporates all of the benefits achieved in the new hull design.
