the larger, forward opening is for the trailer winch line. The next one is for the forestay, the last one is for the jib tack. Best hardware there is a snap shackle that will live there. Best way to secure it is one with a screw-on pin, so you can get a pair of vice grips and really crank it down so no one will steal it. As you will find out, they're expensive! Another trick would be to bed it in epoxy putty after scrubbing it in cleqaning fluid or some other solvent, then crank it down good. If you ever have to remove it you can heat it to about 200 degrees, which will soften the epoxy. Have fun with the boat. jerry ----- Original Message ----- From: <mrh219@yahoo.com> To: "montgomery listserve" <montgomery_boats@mailman.xmission.com> Sent: Sunday, May 24, 2009 5:44 AM Subject: M_Boats: new to me m-15 I have mostly been a lurker here, but my new-to-me m-15 arrived yesterday and has been launched for 1st sail. Question: attaching the tack of the jib. The bow fitting has a large opening and two smaller opening. I attached stay to middle small opening. Is the tack attached to large opening in front, or smaller one behind, and using what? Does the large front opening have a designated purpose? _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats Remember, there is no privacy on the Internet!
