Abstract
A system for maintaining the hull of a sailing boat in a steady position substantially independent of wind pressures on the sail, comprising a pivoted mast and wires connecting the mast with a weight in the boat hull via a transmission device. Transverse pivoting movement of the mast causes lateral displacement of the weight thereby maintaining the hull in a stable condition.
Claims9
A balancing system for a sailing boat, said sailing boat having a hull, said hull having a first and a second side, comprising:
- a mast pivotally attached to said sailing boat and tiltable transversely with respect to said hull;
- a weight within said hull, said weight being slidingly mounted on the bottom of said hull and movable transversely across the bottom thereof;
- a first wire and a second wire, each of said wires having a first and a second end, said first end of each of said wires being attached to said mast;
- a first guide block and a second guide block, said first and second guide blocks being on said first and second sides of said hull, respectively, said first and second wires passing around said first and second guide blocks, respectively, and into said hull;
- and
- means within said hull for transmitting a transverse tilt of said mast to said weight, said second ends of said wires being attached to said means, said means being operably connected to said weight, so that a transverse tilt of said mast in one direction may cause a transverse movement of said weight in the opposite direction, whereby said sailing boat may be maintained in a stable condition,
- wherein said transmitting means comprises a first and a second transmission block on said first and second sides of said hull, respectively, and a weight wire, each of said first and second transmission blocks having a first and a second wheel, said second ends of said first and second wires being attached to said first wheels of said first and second transmission blocks, respectively;
- and said weight wire having a first end, a middle and a second end, said first end of said weight wire being attached to said second wheel of said first transmission block, said middle of said weight wire being attached to said weight, and said second end of said weight wire being attached to said second wheel of said second transmission block.
