Peter. Best recommendation is to take the current set to a rigging shop and have them duplicated. West Marine, for example, will do this. The basics, as shared by Jerry Montgomery, are - 1/8" 1X19 316 stainless wire with a thimbled loop on top, and a swaged marine eye on the bottom. "Regarding the Montgomery 15: the only change I ever made to the standing rigging during the production life of the boat was to increase the length of the forestay about an inch and shorten the shrouds about half that much. Initially, there was an amazing coincidence in that all three wires were nearly the same length; plenty close enough so that the stay adjusters would take up the difference if the forestay was set in one of the last two holes. Only problem was that new sailors would try to balance all the wires to as close to the center of the adjusters as possible which set up the mast too plumb; the 15 sails best with the mast raked aft. As soon as I became aware that people were doing this I simply lengthened the forestay and shortened the shrouds, encouraging owners to set up the mast with a little rake. I hate to see Montgomery boats going slow!" :: Dave Scobie :: M17 #375 SWEET PEA - m17-375.com :: M6'8" #650 :: SV SWALLOW - sv-swallow.com On Tue, Mar 19, 2019, 7:04 AM Peter Zimowsky via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote: Hi guys:

Is there a spec sheet available for M15s like the one posted for M17s? I’ve been replacing my shrouds and forestay and want to make sure I’m doing it right. Thanks,
