I recently had a rigger adj.the standing rig.He had no specs.to go by,and it looked like a generic thing,although he did use a gauge.I,being more or less a perfectionist,called the Cat.factory and they faxed me the specs.They were as follows:back-32,fore-24,upper-35,lower20.I bought a gauge and they all measured 34.
The rigger was a very experienced (well known)person and has sailed extensively.I hate to loosen the stays; are they that critical? I'm interested in knowing what method you use in determining the tension.Do I really need the gauge or can I just eye-ball it.I understand about the mast rake,I'm really just interested in the tension.
Thanks
Steve

You might want to read the following thread on subject.

An overtight rig may put unnecessary stress on the rigging components.

Steve, what do those numbers represent? If your backstay is 34 and Catalina recommends 32, do you tighten or loosen to get 32? I assume lower numbers are looser, higher numbers tighter. Or...?

I also found the tensioning rather confusing. Some points I did notice, however. There are two Loos gauges that are being used, the Model A and the PT1. They give different readings when used. Make sure you know what Loos gauge a person is using when they tell you what the tensions are. The numbers from Catalina are for a Model A. Using a conversion chart, the same numbers for a Loos PT1 are upper 25, lower 16, and rear 23. I set my wires to these tensions using a Loos PT1. I later found that, when close hauled in a 10 knot breeze, this wasn't enough tension to keep from having slack in the leward shrouds. I made slight adjustments equally to both sides until the slack disappeared. As I understand, you want just enough tension on the wires to keep the slack out, NO MORE. That's my two cents, probably about what it's worth. By the way, before I adjusted my wires, they were way, way over tightened. I, however, haven't noticed any difference in the way the boat sails. Good Luck.

What size Loos gauge fits the 250? Apparently, there are different sizes to fit different diameter rigging.

Go read the link above. Not all 250's have the same diameter wires.

and not all wind conditions warrant the same tensions, I would trust your rigger.
