Forspar
I have a Forspar pole. It is approx. 10 to 12 feet long but telescopes to nearly double that length. I use it primarily to pole out my 135 when sailing down wind. The pole is stored vertically against the mast. One jaw end is clipped to a car which then is pulled up the mast on a track. The bottom jaw end is then strapped to the base of the mast. You could get a second car for the bottom end but the results in the pole rattling.Some of my best sailing has been with the 135 poled out to windward, the boom and full main pushed all the way out to leward (with a preventer holding it there) with a steady 25+ knot wind blowing me north from Seattle to Canada. Get one. You won't be sorry.
