Abstract
A ballast system for a sailing boat includes an elongate body having a first end and a second end. A mounting is provided at the first end of the elongate body for suspending the elongate body from a hull of a sailing boat. A ballast weight is positioned at the second end of the elongate body. A motor and gear assembly are provided for moving the second end of the elongate body relative to the hull of the sailing boat. The described ballast system decreases the amount of ballast weight required without sacrificing the safety of operation of the sail boat. The decrease in ballast weight, decreases the over all displacement of the sail boat, and permits increased speed.
Claims6
A ballast system for a sailing boat comprising:
- a single elongate body having a first end and a second end;
- a first pivotal mounting for suspending the elongate body, such that the elongate body is pivotally movable between a first limiting position extending from the pivot position toward a stern of the sailing boat substantially parallel with and closely underlying the hull, and a second limiting position depending substantially perpendicular to the hull;
- an elongate ballast weight having a first end, a second end and a top surface, the ballast weight being pivotally mounted by a second pivotal mounting to the second end of the elongate body, the second pivotal mounting being along the top surface at the centre of balance between the first end and the second end such that the ballast weight maintains an orientation substantially parallel to and underlying the longitudinal axis of the sailing boat regardless of the positioning of the elongate body;
- and
- means for moving the second end of the elongate body relative to the hull of the sailing boat.
