For mast down (on trailer) coverage, a 10'x16' canvas tarp perfectly covers the M15, will last years and survive strong winds, looks good, and only costs about $80. I am experimenting with using two smaller canvas tarps to cover my S17 mast up, not sure how well that will work.... Sailors Tailor makes excellent quality covers and already knows M boats if you're willing to pay for it. I have one for my Catalina 22 and aren't very happy with how much work it is to put the cover on- it's really large and heavy. If it was in smaller pieces that could be put on one at a time, that would make it way faster and easier I think.

I'm kind of thinking about a cover for the M15. I've been using a tarp over the mast, but I'd kind of like a custom cover. Any ideas? Vendors? Prices?
