You are right. A also calculate about 40 lbs side force from the angled backstay and that isn't enough to bend the mast 8". I didn't describe it very clearly since it wasn't bent, just not vertical. The rigger had spent about an hour messing around with upper shroud tensions trying the get them equal and in the process the mast ended up to starboard. He just didn't bother to do a final check.

Assuming the... ]]> feeds@yuku.com (nickwigen) http://catalina42discussionforum.yuku.com/sreply/3568 Thu, 06 Apr 2006 06:23:15 GMT http://catalina42discussionforum.yuku.com/reply/3567/t/Recommended-Rig-Tension.html#reply-3567
It is not clear from your description just what the rigger did, but it does not seem possible that the offset backstay could be the problem.

On our boat the backstay is offset 16 inches from the centerline. Assuming the backstay is 60 feet long, the angle is just over one degree. The lateral force on the top of the mast would be about 2% of the tension in the backstay. If the backstay was tensioned to 2000 pounds, a... ]]> feeds@yuku.com (yorkrose) http://catalina42discussionforum.yuku.com/sreply/3567 Wed, 05 Apr 2006 13:19:27 GMT http://catalina42discussionforum.yuku.com/reply/3566/t/Recommended-Rig-Tension.html#reply-3566 feeds@yuku.com (nickwigen) http://catalina42discussionforum.yuku.com/sreply/3566 Wed, 05 Apr 2006 12:34:54 GMT http://catalina42discussionforum.yuku.com/reply/3565/t/Recommended-Rig-Tension.html#reply-3565 feeds@yuku.com (peter) http://catalina42discussionforum.yuku.com/sreply/3565 Wed, 05 Apr 2006 10:29:59 GMT http://catalina42discussionforum.yuku.com/reply/3564/t/Recommended-Rig-Tension.html#reply-3564
"Real Riggers" don't need no stinkin' tension gauge, but some of us find it useful. In particular it is useful to check if the tension is the same on both sides. The basic rule is always to keep the mast centered and straight laterally. Sighting up the mast is the standard method, but it is not always easy to see small deviations.

The question of tension, even on a straight rig, is always uncertain.
