I've seen a web page with the dimensions for the M17 sails but none for the M15.
Suggest you contact Nor'Sea Yachts where the M-6'8", M-15s, M-17s and M-23s are currently being manufactured. http://www.montgomeryboats.com/ Stan M-15, #177, Carol II _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats
