Thanks Keith. Rick Harper had recommended 12' so that is how far the pole is from the mast. Fun is the plan! And since our total crew weight is pushing 400lbs, more power can't hurt...
It appears you've already cut the pole - but what I did (using an old windsurfer mast) was to cut the pole initially to 13.5', but mount the hardware at 12.5'. That way after sailing it if I felt I wanted to try a longer set up I could just move the hardware out further. I never did, as the 12.5' worked just fine and ended up trimming the end. I guess the message here is as these things are a bit trial and error, give yourself some room to play, trim it down later...
