I've been sailing a recently restored Catalina 22 for a few months but I couldn't get the standing rigging right. Through self-study I have learned how to ensure the mast is properly pitched and centered, as well as how to use a tension gauge to properly pre-tension all masts. This Loos tension gauge is easy to use, accurate and allowed me to get my rig up to factory specs quickly and the results were immediately noticeable in the boat's performance. I will have this tool in my tool box for regular use to keep my rig in top condition.
