ABSTRACT:
A sail line stopper is provided for controlling the hoisting and trimming of sails in which the line may be released under heavy load without abrading the line so released. A U-shaped base member having legs with a pivot pin mounted therein is adapted to be anchored on a sailboat. A cam mechanism includes an inner element having a handle attached thereto which is eccentrically mounted for pivotal movement around the pivot pin. A movable outer element is positioned for pivotal movement and a rotational movement on the eccentrically mounted inner element. One or more springs are mounted between the inner and outer elements of the cam mechanism which are acted on when relative movement takes place between the elements. The spring is compressed when the handle is pivoted placing the outer member in locking engagement with the line in the load direction which locking action is increased with increasing load; while allowing the outer member to rotate or float over the line in the other direction. Each release of the load direction is effected by raising the handle. The line stopper can be released under heavy load because the outer element holding the line rotates in the same direction the line is running, the line will not be abraded thereby limiting line wear. The line stopper may be mounted either vertically or horizontally.
