A fellow Catalina owner approached me today to ask if I knew how to read a tension gauge he acquired with his 1987 C22. We figured it out with the help of a young man who happened to be walking on the dock. However, I couldn't find any values for either a C25 or C22 in looking in both owner manuals, although p. 11 of the C25 has a "rigging specification" reference to the diameter and length of the various stays and shrouds. Kind of looks like maybe only rigging specialists have access to the info, unless someone can point me to somewhere to locate it for a C25 and/or C22. The C22 is rigged very similarly to the C25, with three shrouds per side in a fractional rig, but I'd expect the tension values, if they exist, to be somewhat different for the smaller craft.
Both C22 and C25 National Associations have those recommendations in their members Technical Manual. There are no definitive numbers as the variable of wind speed, flat water, waves, sail and mast height, and keel configuration are always the final variables. The Assoc. Manuals are well worth the $25 to join either association and then purchase the Tech. Manual via download.

The actual settings of the shrouds are very much both personal preference and usual sailing conditions. The essential parameter is that the aft lowers are loosest, the uppers tightest and the fore lowers in between. (For instance, on TSU they read 20,30,25 from aft to forward - which are much too loose for most people). It is not necessary,IMHO, to use the readings on the front to calculate the foot pounds on the back of the guage. The front gives you all the info that you really need. When finished tuning, look up the mast track and make sure that it is perfectly straight all the way to the top. If not, adjust the appropriate upper.
