"clew and tack are strong enough...how do we determine if we have "proper" reinforcement" first is if the sail wasn't loose foot to start the clew and tack are very likely not strong enough. this is especially true for an older sail. when i had some 'extend the life' work done to to my M17 main, including making the sail loose foot, Harry, with E/P sailmakers, reinforced the clew/tack. as DougK stated recutting an old sail will result in a sail/boat that will not be up to 'best performance'. a good main is VERY IMPORTANT to getting the M15 to sail well (also on the M17, but not quite as much because the M17 is a masthead rig and has a backstay ... the genoa/jib on the M17 is a greater part of the running rig than on the M15). a poorly cut/shaped main will make the M15 sail like a dog. the 3/4 rig is driven by the main and a poor sail makes for an unhappy sailor! to add - you want a cunningham on your main. this is an important sail control in adjusting the main's shape by adjusting the luff tension (as done tightening the jib's halyard). :: Dave Scobie :: former M15 owner #288 - http://www.freewebs.com/m15-name-scred :: M17 #375 SWEET PEA - http://www.m17-375.webs.com :: Sage 17 #1 - AIR BORN - http://sagemarine.us/sage_17.html :: Sage 15 sloop #001 - ASOLARE - http://sagemarine.us/sage_15.html :: SageCat #000 - SAGECAT - http://sagemarine.us/sagecat.html On Tue, Mar 14, 2017 at 3:46 PM, John Schinnerer <john@eco-living.net> wrote:
Funny, I was thinking about this question myself as I start to anticipate sailing season...
Same goes for M17 I assume. My old '74 has foot in track.
Key question would seem to be whether clew and tack are strong enough...how do we determine if we have "proper" reinforcement, Dave (or anyone else who can respond to that...)?
cheers, John S.

sorry ... computer decided to send as i was typing.
you MUST have a vang ... it minimum to keep the boom from rising when sailing off the wind.
loose footed is wonderful. makes the sail shape better and provides for easier adjustment of the sail's draft using outhaul. NOTE: the sail needs to have proper reinforcement at the clew and tack.

I have been sailing my M15 with the main fitted in the boom groove but
recently it has been suggested that flying it loose footed, with only tack and clew fastened, will improve performance. I have also been advised both for and against adding a boom vang. I appeal to this forum for an experienced opinion.
