Abstract
Provided is watercraft hull system, including a hull having a fore end, an aft end, and a longitudinal axis extending between the fore end and the aft end; a substantially V-shaped portion extending from the fore end toward the aft end along a portion of the longitudinal axis; and a substantially M-shaped portion extending from the V-shaped portion toward the aft end, wherein the V-shaped portion gradually transitions to the M-shaped portion.
Claims20
A watercraft hull system, comprising:
- a hull having a fore end, an aft end, and a longitudinal axis extending between the fore end and the aft end;
- a V-shaped portion extending from the fore end toward the aft end along a portion of the longitudinal axis;
- and
- an M-shaped portion extending from the V-shaped portion toward the aft end, wherein the V-shaped portion gradually transitions to the M-shaped portion,
- wherein the hull includes a first starboard chine, a second starboard chine, a third starboard chine, a first port chine that extends from the first starboard chine at a centerline that runs along the longitudinal axis, a second port chine that extends from the second starboard chine at the centerline, and a third port chine that extends from the third starboard chine at the centerline,
- wherein the first starboard chine and the centerline define a first starboard side hull area, the first port chine and the centerline define a first port side hull area, the second starboard chine and the first starboard chine define a second starboard side hull area that extends starboard from the first starboard side hull area, the second port chine and the first port chine define a second port side hull area that extends port from the first port side hull area, the third starboard chine and the second starboard chine define a third starboard side hull area that extends starboard from the second starboard side hull area, and the third port chine and the second port chine define a third port side hull area that extends port from the second port side hull area, and
- wherein the second starboard side hull area and the second port side hull area have a positive deadrise in the V-shaped portion that gradually decreases in angle from the fore end to a zero degree angle at a furthest aft end of the V-shaped portion and have a negative deadrise in the M-shaped portion that gradually becomes more negative from the zero degree angle where the M-shaped portion is adjacent the V-shaped portion to a final negative angle.

- wherein the first starboard chine and the centerline define a first starboard side hull area, the first port chine and the centerline define a first port side hull area, the second starboard chine and the first starboard chine define a second starboard side hull area that extends starboard from the first starboard side hull area, the second port chine and the first port chine define a second port side hull area that extends port from the first port side hull area, the third starboard chine and the second starboard chine define a third starboard side hull area that extends starboard from the second starboard side hull area, and the third port chine and the second port chine define a third port side hull area that extends port from the second port side hull area,
- wherein the second starboard side hull area and the second port side hull area have a positive deadrise in the V-shaped portion that gradually decreases in angle from the fore end to a zero degree angle at a furthest aft end of the V-shaped portion and have a negative deadrise in the M-shaped portion that gradually becomes more negative from the zero degree angle where the M-shaped portion is adjacent the V-shaped portion to a final negative angle;
- and
- a motor coupled to the hull.
