ABSTRACT:
A halyard stopper for a sailboat includes a pair of spaced-apart side plates extending up from a base. A jamming arm in the form of a class two lever is pivotally mounted between the plates above the base adjacent the entrance end of the stopper so that the arm can be swung from a jamming position wherein its free end is disposed close to the base and a nonjamming position wherein its free end is spaced further away from the base. A class one lever pivotally mounted between the side plates adjacent the exit end of the stopper is swingable so as to engage the free end of the arm and move the arm from its jamming to its nonjamming position even though the arm is under a very large jamming load.
