Thom, I had to re-read your post. ADD LOL The sail has to have a "belly" in it to work right. Sounds like you are OK Mike in MI -----Original Message----- From: Thom Loftus Sent: Tuesday, March 11, 2014 5:30 PM To: W David Scobie ; For and about Montgomery Sailboats Subject: Re: M_Boats: proper boom placement Hi Dave. 1987. The main is older I think, but in good shape. The previous owner didn't sail much and there's no indication that it's blown out. ________________________________ From: W David Scobie <wdscobie@yahoo.com> To: Thom Loftus <thom_loftus@yahoo.com>; For and about Montgomery Sailboats <montgomery_boats@mailman.xmission.com> Sent: Tuesday, March 11, 2014 2:26 PM Subject: Re: M_Boats: proper boom placement Thom: what year is your M15? how old is the main? :: Dave Scobie -------------------------------------------- On Tue, 3/11/14, Thom Loftus <thom_loftus@yahoo.com> wrote: Hello All. I've recently replaced the mast on my M15 and have noticed that when my mainsail is hoisted as far as it will go up the mast, and the luff is relatively taught, that the end of the boom droops at a downward angel from the gooseneck when the topping lift is eased. It's almost as if the foot of my mainsail is cut at an angle, but I can't confirm that at the moment. In looking at pictures online, it is difficult to tell if this is the way the boom is supposed to sit, or if there is something wrong with my rig. I have not yet installed a boom vang and I don't actually know how high off of the deck the boom should sit at the gooseneck. I have no cunningham rigged and to keep the boom from inching up in the mast, I usually tie it to the deck from a loop in the gooseneck. Can anyone enlighten me as to how hight off the deck my boom should sit and whether or not the boom should angle down as it moves aft? Thanks Thom
