I wanted to ask what the more experienced members here think is the proper shroud tension on the C22.
I have a Loos PT1 gauge and was tensioning the shrouds this weekend on my new design 87'. Right now, I have them settled in at 10 for the aft lower, 25 for the uppers, and about 19 for the forward lowers, measured with the PT 1 Loos gauge. I have about 6 1/2" rake, measured at the boom. I should add the forward lowers are extended the full adjustment at this tension, and only have about 1 thread inside of the top turnbuckle, which seems awful close to the limit of the turnbuckle. I have the Catalina Direct quick release turnbuckles on the forward lowers.
In reviewing the C22 tuning guide by Pete Harper, the guide states - for medium winds - using the older Loos Model A gauge:
Uppers: 25
Forward lowers: 17
Aft lowers: 10
However, the North Sails tuning guide for the C22 states - using the older Loos Model A gauge:
Uppers: 28
Forward lowers: 24
Aft lowers: 24
I haven't had the boat in the water yet, so I haven't had a chance to see how they might slacken or tighten under pressure from the sails.
There seems to be a big difference of opinion as to the tension on the lower shrouds. Is there any consensus on this issue?
Also, what tension is generally recommended for the backstay and headstay? I wasn't able to find any real objective measurements. I have about 6 inches of headstay sag at the current set-up, with a CDI roller furler.
Thanks for any advice or comments-
