Boat hull

Abstract

An improved boat hull is described. The new hull includes a bow, a stern and a lower longitudinal keel extending between the bow and stern. The hull includes a first V hull formed at the bow and a second V hull formed aft the bow. The second V hull is defined by a bilaterally symmetrical indention having a forward end and a rearward end. The indention is directed rearwardly and outwardly from the lower longitudinal keel, and the rearward end of the indention is above the water line for displacement of water toward the stern on both the portside and starboard side of the boat. The new hull provides a smooth, less jarring ride, a reduction of drag forces, and an improved load along with increased deck area.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates generally to boats and, more particularly, to a boat hull design.[0002]Traditional recreational boat hull designs are in the firm of a V at the bow. They cut the water and divide the spray outward to the starboard and port sides of the boat. Transitioning from the bow to the boat's stern, however, the remainder of the hull resumes a more or less flat planar shape known as a “modified V.” When hulls with this design impact large waves, the boat is lifted by the wave and then impacts the flatter mid portion of the vessel causing a jarring rough ride. Another problem with traditional hull designs is drag.[0003]The midsection of the hull presents substantial surface area that contacts the water. Vertical acceleration when attempting to plane the craft is not optimum as a result. Drag reduces fuel efficiency and performance as well. Drag can be reduced in designs like the catamaran, which uses spaced twin hulls. But, it's a trade off...

AI Technical Summary

Benefits of technology

[0006]The invention relates generally to boats and, more particularly, to a boat hull design. The new design provides a smoother ride with less drag in any waterway that can produce large waves, including seas and coastal / intercoastal waters. The novel invention provides a double V hull design that effectively dampens the impact of large waves. A unique bilaterally symmetrical indention aft the bow serves as a second cut into the water to direct spray rearwardly and outwardly from the keel.

[0011]One object of the invention is to provide an improved boat hull design that provides a smoother ride with less drag resulting in improved fuel economy and performance. Related objects and advantages of the present invention will be apparent from the following description.

Problems solved by technology

Transitioning from the bow to the boat's stern, however, the remainder of the hull resumes a more or less flat planar shape known as a “modified V.” When hulls with this design impact large waves, the boat is lifted by the wave and then impacts the flatter mid portion of the vessel causing a jarring rough ride.

Another problem with traditional hull designs is drag.

Vertical acceleration when attempting to plane the craft is not optimum as a result.

Drag reduces fuel efficiency and performance as well.

It is difficult to steer catamarans, and their turn radius is too wide.

Deck support, however, is lacking in this three-point design.

Lack of support presents another problem to boating enthusiasts who desire more spacious decks on their boats.

Waters with large waves are not enjoyable for trailerable boats with large deck space, like a houseboat or pontoon.

This places limitations on the utility of the size of boats that can be used in the Great Lakes, seas and coastal / intercoastal waters.
