Boat Hull

Abstract

A shallow draft boat having a boat hull that allows for stability, maneuverability, and speed while needing only inches of draft. The hull generally includes a ski, a bottom shell, a left and right chine and a bow wrapper.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This utility patent application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 384,079 entitled “Boat” filed Sep. 17, 2010, the entire disclosure of the application being considered part of the disclosure of this application and hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present invention is directed to a boat hull and more particularly, a boat hull that allows for stability, control, quick maneuverability, quick stops, and a fast top end speed in a wide variety of water conditions while needing only inches of draft.[0004]2. Related Art[0005]At times, boat operators and in particularly, the military and law enforcement agencies need boats that are stable, maneuverable, have plenty of speed and can quickly stop yet are able to operate in mere inches of water. Currently, the only boats that successfully operate in mere inches of water of any significant size and speed...

Benefits of technology

[0006]The present invention is directed to a boat hull and more particularly, a boat hull that allows for stability, maneuverability, and speed while needing only inches of draft.

[0013]The bow wrapper has unique characteristics that provide very quick stops for a boat of the relative size and prevents submarining, substantially through the expanding spoon shaped profile of the bow wrapper, particularly the upper bow wrapper. More specifically the bow wrapper is configured to increase buoyancy of the hull the further the hull pivots perpendicular to the overall length until at least the transom and a portion of the ski, the bottom shell and a right chine and a left chine are free of the water proximate to the transom. The bow wrapper includes an expanding curvature as the distance increases from the transom and as the distance increases in height from a plane formed by the ski. This allows the bow wrapper to change from an angular profile proximate to the shell to a rounded expanding curvature as the distance increased from the shell. The bottom shell increases from approximately a 7-9 degree dead rise proximate the transom to a 21-27 degree dead rise proximate to the bow wrapper.

[0014]The boat hull extends between a transom and a bow and having a beam and an overall length, and includes a ski having an approximately triangular shape to define a first side disposed along the transom and second and third sides extending from the first side towards the bow along a ski plane, a bottom shell extending outwardly from the second and third sides to a left chine and a right chine and wherein the bottom shell has a transom dead rise between 6 to 10 degrees proximate to the transom and relative to the ski plane to minimize vertical displacement of the chine relative to the ski plane, and at least one skeg coupled to the bottom shell and disposed proximate the transom and inwardly from the left chine and the right chine to prevent roll-out during high speed turns. The boat hull, specifically the bottom shell has a first dead rise between 6 to 10 degrees measured between the transom and a length of approximately 25% of the overall length from the transom to minimize vertical displacement of the chines relative to the ski plane within 25% of the overall length from the transom. The bottom shell has a second dead rise between 9 and 21 degrees measured between a length of approximately 50% of the overall length to a length of approximately 75% of the overall length from the transom.

Problems solved by technology

The problem with airboats is that they are very noisy as they are driven by an aircraft type propeller and they are flat-bottomed vessels which make them difficult to turn and many times, they are top-heavy which causes the airboats from time to time to capsize.

Airboats also are limited to substantially flat water and therefore cannot be used on most lakes, bays, or oceans where waves commonly occur.
