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
Tom: sheeting angle details - http://www.sailmagazine.com/headsail-sheeting a bit simplified concerning setting the rake of your mast: rake of the mast isn't set using the backstay adjuster. the backstay adjuster adjusts bend of the mast. OK video here talks about adjusting the backstay and sailing performance - http://youtu.be/9GDro9i1ye0 rake is the 'static' setting of the mast as set using all the shrouds. start with about 4" of rake. easy way to measure is, with the boom off, is to hang the main halyard down to the cabin top and measure the offset from the mast's rotation pin.. see how you like the boat's behavior and adjust forward or aft to preference. again, my definition of rake (static mast set) v. bend (changed used backstay adjuster) is simplified. -- :: Dave Scobie :: former M15 owner - www.freewebs.com/m15-named-scred :: M17 #375 SWEET PEA - www.m17-375.webs.com On Thu, Jan 29, 2015 at 10:01 AM, Thomas Buzzi <thomaspbuzzi@gmail.com> wrote:

Thanks for the quick reply, Dave, Palm to forehead, of course, rake and bend are two different things. I knew that!! I will check out the suggested websites. Fair winds, Tom B On Thu, Jan 29, 2015 at 11:52 AM, Dave Scobie <scoobscobie@gmail.com> wrote:

Dave, The webpage about sheeting angle track placement was very helpful. Not so much the back stay adjustment site. It seemed just the opposite of what should work on depowering the sail. The latter site seemed to also state that there was little to be gained trying to tension the backstay on a masthead rig like the Mont 17 has.
