Tuning a rig
i also have a '77 h30 and have spent considerable hours trying to tune the rigging. What I discovered was that it is easier to tuna fish than tuna rig. That being said, I finally got less fanatical about it and set the back stay so the jib furler was not too tight nor too loose - watch the mast rake - and set the lower shrouds' tension a bit less than the uppers. I originally used a Loos guage to get it in the ballpark. Looked up the track - easier with a mirror - to make sure it was fairly straight. Next step is to take it out on a blustery day and put it to the test. With someone at the helm when you are hard on the wind, take a look up the mast from the front and sides. Check it out on different tacks and reaches. If you like what you see, let it be. Check the tension manually everytime you get on the boat and if no difference, you are good to go. Don't lose any sleep over it. Now, if you are going to race, well....... Hope this helps. -R. Fraulein II
