Andrei, Your sail may have shrunk over the years - Measure the mast extrusion from end to end of the 'tube'. That is the measurement that will be the determining factor. Good luck. Have fUn, go sailing! GO On Fri, Sep 10, 2021 at 11:29 AM Andrei Caldararu via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
Hello fellow Monty owners, I am the owner of "Seaweed", a 1982 M-17, galley style, serial number MMP173490482. I've owned it since 2008 and have been very happy with it. It has now come time for me to order new sails for it; the old ones are almost 40 years old and show it. I talked to Harry at EP Sails, and he told me that based on his information the luff of the main could be either 19'4" = 232" (for the standard rig) or 20'9" (for the tall rig). However, when I went and measured my old main, the luff came to 222.5", which is about 10" shorter than even the standard rig. I am hoping that maybe someone remembers whether a number of M-17's in that time period were made with shorter masts, and what the sizes of the sails for this shorter version was. I am planning on ordering a main and a standard jib -- my old genoa is in good shape, and I don't use it much on Lake Michigan. Thanks for all suggestions! Best,Andrei.
