Problems solved by technology

Unfortunately, one commonly known disadvantage of the V-shaped hull is its lack of stability on water with a hard drive in rough water and significant side rocking.
Another drawback of the V-shaped mono-hull is its significant drag and draft, which thus require significant power to cruise the boat at high speeds.
Though this multi-hull boat is able to cruise at a generally faster speed, it is more affected by pitch polling ...

Embodiment Construction

[0023]The present application describes a mono-hull structure with improved stability and less fuel-consuming. The mono-hull structure is suitable for water surface boats powered by engine propulsion, such as yachts, marine transportation boats and like displacement boat implementations. “Displacement boat” means that the boat vessel glides smoothly through the water, in contrast to the “planing boat” which rises up on top of the water.

[0024]FIGS. 1 through 5 are schematic views of a hull structure suitable for a mono-hull boat vessel according to an embodiment of the invention. The boat hull 100 includes an elongated hull body 102 which forms a sharp bow 104 and widens towards the stern 106. The hull 100 has a generally V-shaped cross-section near its bow 104, which progressively widens into a U-shaped cross-section towards the stern 106 with a bottom surface 108 linking two lateral flanks 109.

[0025]As shown, the V-shaped profile of the hull body 102 near the bow 104 forms two flan...

Abstract

A boat hull comprises a hull body having two lateral flanks linked by a bottom surface, and at least two propulsion compartments provided in two bulges protruding below the bottom surface of the hull body. Each propulsion compartment lodges a propulsion engine located below the bottom surface of the hull body. The propulsion engines are located at the deepest position in the hull and below the water plane.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to boat hull designs, and more particularly to water surface vessels provided with a mono-hull structure and powered by engine propulsion.DESCRIPTION OF THE RELATED ART[0002]A variety of different boat hulls have been implemented in diverse types of conventional water surface vessels. Continued demands for stability and increased speeds stimulate further developments in boat hull designs.[0003]In certain mono-hull water vessels known in the art, the boat hull has a generally V-shaped profile for cutting through water. Unfortunately, one commonly known disadvantage of the V-shaped hull is its lack of stability on water with a hard drive in rough water and significant side rocking. Another drawback of the V-shaped mono-hull is its significant drag and draft, which thus require significant power to cruise the boat at high speeds.[0004]The trimaran or catamaran is another type of boat which assembles a plurality of thin...
