Andrei: two reef points, or maybe even three. with the type of winds, thunderstorms and seas you get on the great lakes three seems, IMO, a better choice. a storm jib isn't all that much money for the M17. i've read that some use a potter 15 jib. dave scobie M17 #375 - SWEET PEA visit SWEET PEA's www-site - http://www.m17-375.webs.com --- On Wed, 5/5/10, Andrei Caldararu <andreic@math.wisc.edu> wrote: I am thinking about ordering a new main sail from EP for my M-17, and I was wondering if I should go with one set of reef points or two. The difference is about $90 (the total cost is about $700). I plan on sailing often on bigger water (Lake Superior, Lake Michigan), so I thought the ability to reef more would be useful. On the other hand the smallest foresail I have is a 100% jib, so maybe getting a smaller one should be my first priority... Opinions? Thanks, Andrei.
