Abstract
A power boat having an improved hull including concave aft sections, and which hull is capable of operations at a wide range of speeds with low relative horsepower for vessel weight and improved fuel economy is disclosed. In one exemplary embodiment, the boat is a 38 foot power boat having an improved hull which can achieve speeds of up to about 18 knots, with a 200 hp engine and which burns about 10 gals. per hour. The hull preferably includes a negative deadrise angle at the aft sections, the deadrise angle being positive at the bow and transitioning to a negative angle at the aft sections of the hull.
Claims19
An improved hull having a waterline, the hull including:
- a forward section having a positive deadrise angle as measured from a centerline of the hull relative to the waterline;
- an aft section having a concave bottom as measured relative to a static waterline, the concave bottom being defined by a negative deadrise angle;
- and
- a midship section disposed between the forward and aft sections, the midship section having a transitional deadrise angle less than the deadrise angle of the forward section and greater than the deadrise angle of the aft section, as measured from a centerline of the hull relative to the waterline.
An improved hull having a waterline, the hull including:
- a length;
- a width that is less than about ⅓ of the length;
- a forward section having a positive deadrise angle as measured from a centerline of the hull relative to the waterline;
- an aft section having a concave bottom as measured relative to a static waterline, the concave bottom being defined by a negative deadrise angle;
- and
- a midship section disposed between the forward and aft sections, the midship section having a deadrise angle greater than zero, as measured from a centerline of the hull relative to the waterline.
