My M15 came with a mast crutch made from 3/4- inch stainless tubing with a "V" welded to the top. Pintles are welded to the tube which fit into the gudgeons on the transom. Because I could not get the boat, trailer, mast, crutch setup into our garage without some disassembly, I shortened the tubing about 16-inches. My forward mast carrier is an extended section of the vertical winch post. I shortened it so that the mast rides about one inch above the bow pulpit. The whole assembly now fits through our seven-foot garage door. Stainless tangs are welded to the aft crutch for stabilizing and lashing lines. I fabricated a 24-inch oak extension which attaches to the aft crutch to elevate the mast in preparation for raising or lowering. I stand on the cabin top and straddle the mast to raise or lower the mast and rigging. It is a pretty simple one-man operation on an M15. I usually protect the cabin top with a life vest or cushion while preparing the mast for raising. I ordered a quick release clamp but my forestay fitting and wire length were all wrong, so it went back to WM. To ease the installation of the forestay pin, I run a slack line from the mast to the bow pulpit, put my body weight on the line, align the forestay with one hand and insert the quick pin with the other. Necessity being the mother of invention, I hit on the idea of a weighted (by me) tensioning line one day after wrestling with an almost-but-not-quite pin alignment. Joe Kidd M15 #207 "Poco a Poco"
