The jockey pole reduces the loads and minimises the wear on guys and life lines when using a spinnaker at Broad Reach.

Connected to the side of the mast it keeps the foreguy/windward guy away from the  stanchions and cap shrouds and also makes for a more efficient angle of the guy. 

The inner end is a regular spinnaker pole fitting and the outer end is an open jaw with a sheave. Fit a fixed eye on each side of the mast. Tie the jockey pole to the cap shroup when used. The pole features plastic spinnaker pole savers on the sides to prevent wear and tear.
