Jerry: Thanks for the input. Nice to hear from the Daddy of the M-15 (as Lyle said - the best boat I never designed). Its being cut as a true Genoa so hopefully I can do either. I never seem to get to run very much, no matter which way I head, the wind is always forward, but hope springs eternal. I'll mount turning blocks on the toe-rail and tracks on the combing per your suggestions. Randy, thanks for the input. The dimensions are a great help. Thanks All - I'll send pictures to the TrailersailorBB site when I get them. Fair winds - Don
