When I bought a new main for my M-17 in 2010 I didn't realize that I had ordered a loose-footed sail. It turned out to be a happy accident. I like the fact that I have much more control over draft. My mainsheet runs from mid-boom to a traveler at the forward end of the cockpit, and I have not found a need for a vang.

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. Thanks, Paul, M15 #471 Callisto -- Paul McAleavy 608-576-9006 Contract Customizing
