In SPEED SAILING, Gary Jobson wrote the following for the 9.1 "Mast Rake 8 to 10 inches of rake. The 9.1 needs helm in light air. Add rake to increase helm. Forestay extended approximately three quarters of the way. Mast bend: After setting forestay length, move mast butt approx. 1-1/2 to 2 inches to induce 2- to 3-inch prebend. Maximum bend should be 8 to 10 inches with backstay on hard(no baby stay). Leeward upper should not go slack with maximum backstay, full main, heavy #1, six to seven people on high side. Tighten lowers and intermediates to remove any sag. Don't overtighten." He also recommends the leeward upper be just firm at 20 degrees heel as does our boat's manual. | ||

Is anyone willing to share numbers in terms of lbs.of tension reading on the rod gauge? I have a gauge but am still fighting the rig. I believe I have 1150 lbs in my uppers, 750lbs. in my lowers and below the scale in the intermediates. This seems to equate to the tension suggested in the manual to get the leewards just un-taught at 15 knots. I'll check those numbers and report again. My forestay has a Harken foil on it so it can't be gauged-any suggestions? How about on amount of pre-bend? Or rake? | ||

If you tighten down the rig too much, the boat is dead in anything light to moderate. It is perfectly appropriate for the leewards to sag off in 18 knots of apparent. Good news: the original owner's manual has a succint discussion of tuning the rig. That's the manual in the small brown 3-ring binder. Alternatively, I recall that Gary Jobson discussed tuning the 9.1 in his book Speed Sailing (hope I remember the name correctly) - this was in a discussion of the Liberty Cup series. However, I don't now have the book - someone in the Cleveland fleet had it, and passed it around among the 9.1 owners. Good luck. | ||

I too would appreciate any helpful tips from the more experienced 9.1 sailors. My leewards go slack in more than 18 kts. It is worse with some backstay on. I have tightened them a little but am being cautious because of all the work I had done on the mast step and I am still checking to make sure nothing is moving. I seem to have about an inch of turnbuckle adjustment left, but I am definitely getting near the limit of adjustment. I am also unsure of how to tune rod without the rod gauge. I always tuned my smaller boat by numbers using a guage. | ||

I am writing from the Chesapeake Bay. I am new to the boat and am interested in finding out the shroud tensions for various wind conditions for the S2 9.1. We have the rod rigging and it is confusing! Please e-mail mckinneys@mhs-pa.org with any help. Thanks alot! Stewart McKinney Gael Forse | ||
