Abstract

An improved boat hull which is useful for various types of boating activities; having a top or perimeter surface, curvilinear bottom surface, curvilinear side surfaces, curvilinear front and rear surfaces. Hull is formed, fabricated or manufactured as a combination of compound curves and straights. The top or perimeter of the hull is to be attached to a standard or non-standard deck configuration. The front, sides and rear of the hull are convex, concave, compound curves and straights, for engaging in contact with water and with a combination of water and air. The front end or bow section of the hull features primarily convex/outward construction in a rounded or somewhat of a ‘v’ shaped configuration, while the remaining portion of the hull graduating to the rear and exiting at the stern, or transom, features a series of concave and convex curves and straights producing a dual-hull or somewhat of a double ‘v’ tunnel configuration. The hull in cross-section longitudinally is a mirror image of itself and is symmetrical.

I claim:  
     
         1 . A boat hull whose outward appearance somewhat resembles that of conventional hulls but whose underside characteristic reveals a combination of compound, convex and concave curves, and straits; and that this combination of convex, concave, curves and straits, creates a hull which provides both hydrodynamic and aerodynamic characteristics and appearance when stationary or underway, further comprising: 
 1. A dual propulsion or single propulsion system.    2. A dual rudder or single rudder steering system.    3. An air-cooled or liquid-cooled propulsion system.    4. A gasoline powered, electrical powered, jet powered, diesel powered, turbo powered, ethanol powered, nitro powered, or powered by alternative energy system.    5. A fabrication process typical to the boating industry including fiberglass, wood, aluminum, ferro-cement, carbon fiber, and alternative fabrication processes.    6. A manufacturing process typical to the boating industry including thermo-forming, vacuum-forming, rotational molding, injection molding, and alternative manufacturing systems.    7. A hull that can be used in either fresh, brackish or salt water.    8. A hull that can be used for/with racing craft or pleasure craft.    9. A hull that can be used for full-size power boats or remote control scale models, or non remote control scale models.    10. A boat hull that combines the benefits of hydrodynamics and aerodynamics.    11. A boat hull that when underway captures air and wind simultaneously resulting in an aerodynamic efffect.    12. A boat hull that when underway captures air and wind and interacts with water resulting in a hydrodynamic effect.    13. A boat hull that when underway lifts at the convex bow end, as a result of wind and water forces, and corrects or stabilizers itself when combination of air and water make contact with the gradual concave compound curves and straits between the dual-hull configuration exiting at the stern.    14. A boat hull that when underway rides on water and causes a hydrodynamic effect.    15. A boat hull which through its diversity can be used on sailing vessels.    16. A boat hull that when angled side-to-side allows the boat to stabilize itself as both water, air and wind work together simultaneously.    17. A boat hull that features a somewhat conventional appearance from the exterior.    18. A boat hull whose single hull graduates to a dual-hull configuration and whose dual-hull becomes a tunnel, which captures water and air and wind simultaneously, when exiting at the stern, preventing the boat from flipping end over end from stern to bow or bow to stern.    19. A boat hull, whose undercarriage creates a hydrodynamic and aerodynamic wing.    20. A boat hull, whose design is predicated on its combination convex and concave characteristics. This hull starts as a convex bow with compound 3-dimensional curves and graduates to a convex tunnel dual-hull mid section and stern, with a combination of concave and convex compound surfaces.    21. A boat hull design that begins as a single bow front graduating to a dual-hull or catamaran type stern.    22. A boat hull which has the ability to help prevent an end over end potentially uncontrollable catastrophic situation, in situations when air and water interact creating an unpredictable scenario.
