3) As far as the rig tuning I will like to be able to
measure the stays tension. I do have some sag on the
head stay but I am not sure how much is acceptable.
any thoughts here.
As Caleb mentioned, rig tune is achieved by use of a No. 90 or PT 2
Loos gauge. My recollection is that base rig tuning specs are in the
Tartan 27 Owner's Manual published by the Chesapeake Bay Tartan
Sailing Club. I don't have access to my copy at present, but I'll be
glad to check and post the recommended rig tuning.
I am somewhat curious regarding your statement about headstay sag. Do
you have a backstay adjuster, and have you tried tightening the
backstay tension, which would also flatten the main?
