Benefits of technology

[0004] According to the present invention there is provided a hull for water craft comprising traditional hull shapes with the hull splitting into two toward the stern with the width at the waterline being substantially maintained. The average waterline width is thus increased while flow of water past and under the craft is not significantly restricted. The inner part of splits may have a sharp angle where the two sides converge to facilitate the break with the water flow, which facilitates planing. The same configuration can be used on tunnel hulled and multi-hulled

Problems solved by technology

As the average width at the waterline is significant for the stability of craft any narrowing of the waterline affects adversely the stability of the craft. contact with the water and more easily o

Embodiment Construction

[0047] Referring to the drawings: [0048]1=a boat hull; 2=the Bow; 3=the Stern; 4=a swallow tail hull section; 5=a transom; 6=a tunnel; 7=a hook keel; 8=a sharp edge; 9=an inside side of a swallow tail hull section; 10 an outside side of a swallow tail section; 11=a waterline; 12=an outside side concave section; 13=concave sections; 14=hatched areas denoting areas below the waterline—or wetted areas; 15=keels; 16=hull section connection

[0049] Referring firstly to FIG. 1, a water craft hull (1) viewed from below has a bow (2) with the body of the hull (1) extending to the stern (3) where it splits into two sections forming swallow tails (4) connected by a transom (5). The transom (5) may be located anywhere along the swallow tails (4) or forward of them. The swallow tails (4) may start to split from the keel (15) or keels (15) and splay out anywhere aft of mid-ships. The split may begin below the waterline and extend aft below the waterline extending from the keel line (15) aft and o...

Abstract

A water craft is disclosed where the hull divides in the aft section from or near the central fore and aft line of the craft and sweeping out toward the beam of the craft on both sides so that a roofed swallow tail is formed with its widest separation toward the stern of the craft allowing smooth motion through the water while providing maximum stability.

Description

TECHNICAL FIELD [0001] The present invention relates to an improved hull for water craft. DESCRIPTION OF RELATED ART [0002] Water craft hulls typically have a pointed end known as the bow and widen in breadth toward the middle of the craft and then tend to narrow in breadth toward the stern. This traditional configuration of hulls is well known. The width of the hull at the waterline typically goes from a point at the bow to the widest about mid-ships and narrower at the stern. Displacement and semi displacement hull forms tend to narrow significantly at the stern while planing craft tend to narrow less at the stern and have a sharp angle where the bottom of the boat meets the transom. [0003] As the average width at the waterline is significant for the stability of craft any narrowing of the waterline affects adversely the stability of the craft. contact with the water and more easily or even being able at all to Displacement and semi displacement hull tend not to have the sharp edg...
