im considering making a stainless steel "bridge" that would go over the tiller cutout in the transom of my capri 18. it would look like a grab handle and be made out of tubing with welded flanges and bolted to the top of the transom on either side of the tiller. at the center would be a mounting point for the mainsheet blocks. this would remove the mainsheet mount from the backstay and put it in the middle of the transom. then you wouldnt have to adjust the mainsheet every time you came about. if i do indeed make this i will post pics.
