After reading several articles about mast rake and how to achieve it, there seems to be two different ways to do it. One, the backstay tensioner, the second using a jib halyard winch setup on the cabin top. Not sure how that second method works but I include it here to hopefully get some ideas from others on this site. I can go either way at this point in rerigging my M-17 for better weather in March. Second issue, Jerry has spoken about using a small jib track mounted on the cabin top for jib sheets for an 80% high cut jib for tacking into 20 knot winds. He suggested a 12-14% angle on the sheeting. I am not sure which elements of the rig to use in determining that 12-14% angle. I don't want to drill a lot of extra holes in the deck by mistake so any help with this would be much appreciated. Thanks for any ideas on these matters. Fair winds, Tom B, M-17, #258
