I installed a topping lift on my M15. A thin dacron line (minimum stretch) is tied to the end of the boom; goes to the mast top through a small block mounted on the Stbd side of the mast, and then down the mast to a cleat. This way I can raise the main, and loosen the topping lift; or do the reverse. It works fine as is, and I see no need for any modifications to the basic set-up. When I furl the main and put the sail cover on it, I pull up the topping lift a bit before tying off the main sheet to keep the boom from waving to and fro from power boat wakes. Can't live without a topping lift! Connie ________________________________________________________________ GET INTERNET ACCESS FROM JUNO! Juno offers FREE or PREMIUM Internet access for less!
