  • Patent number: 6058867
    Abstract: A mechanism to improve performance and increase the speed of a sailboat by inclining the sailboat's mast and its supporting stays from side to side, enabling a sailor to lean the weight of his mast, sails and rig against the pressure of the wind. This is accomplished by placing the mast into a tube that is affixed to a tube that is bent to a radius and is supported by a cradle of hourglass shaped rollers. The shroud stays are then attached to the upper end of the tube with the radius that is stabilized by a strut back to the mast tube. The mast and shrouds can then be inclined as a structure rolling it from side to side in its cradle of rollers. The mechanism can then be operated by a variety of methods depending upon its application.
