Michael. If you have the mast rake set (about 4") the forestay should just be to hard to insert the pin. Attaching the jib halyard and giving it a yank so can just get the forestay bow plate pin installed the tension is correct. Can't get the pin in, to tight. Easy to install the forestay pin the rig isn't on loose. Make sure the mast isn't strait up/down fore-to-aft. The mast needs to be racked and there should be slight weather helm. Yes the lee shroud will be loose when going to weather. The M15/17 and Sage 15/17 and SageCat rigs all run 'snug' not tight. All are 'tuned', with different amounts of rake, the same.

Dave, and RustyThanks for the quick response and photo. Yes, my shroud adjusters are same as in your photo. I've attempted nothing sophisticated to tension. I like to see just a little noticeable slack in the leeward shroud when the boat heels in a moderate wind. Presently, lots of slack but I thought not enough to go to the next hole. Wanted to check the wisdom of the group before trying to tighten.Thanks againMike WM15 #139

Shroud adjusters, see picture, are stock and how Jerry delivered all his M15s. Turnbuckles result in an over-tensioned rig.
I discuss in detail how to adjust the M15, including rake, in the Facebook MSOG group. Are you a member?
How are you determining rig tension?

My 1981 M15 has turnbuckles that look like parts from an Erector set. (A series of 12 holes for inserting the clevis pins) None of the settings result in appropriate shroud tension. Is there another type of tension device M15 owners are using? I am unable to find a jaw-to-jaw turnbuckle short enough to do the job. Appreciate your help. Mike W M15 #139
