whisker pole
Sounds like the previous owner never used it for a spinnaker. The whisker pole is designed to hold the clew (leeward, rear corner) of the jib/genoa outboard when running downwind or reaching in light air. I doubt you have all the hardware and fixtures for a traditional (symetrical, racing) spinnaker. A spinnaker pole is designed to hold the forward, or windward corner of the sail out front and windward of the forestay. Use your whisker pole for what it is intended. My whisker pole's large end is the inboard end and the smaller is the outboard end, which is clipped to the sheet, not the sail or nor inside the bowline's loop. I use a spare halyard clipped to one hole in the outboard end to control the attitude. I clip a preventer line to the other hole on the outboard end and run it down to a block on the forward rail then back to a convenient cleat. This controls the angle, which affects the foot's curve and keeps the pole from bouncing up and down. The height of the pole is controled at the mast. On a large sail, such as a 150 genoa, the pole may be anchored to a fitting placed outside the shrouds taking advantage of the pole's adjustability.If you want a spinnaker, get a cruising, or asymetrical chute. It does not require a pole and two people can easily handle the sail. Go to www.CruisingDirect.com for details on rigging, trimming, sizes and prices. Trust me when I tell you that acquiring an "A" kite will enhance your sailing experience many times over.
