George, see the archive section for smaller boats
There has been a lot of info on this subject, in the last 3 months, that is very worth while to see and copy.Once you know how to do the tensioning you can contact Hunter Marine and they will supply the % of tension for the shrouds and stays. It is usually 20% of breaking strength.A "Loos gauge" costs $50 and takes the guess work out and when done you will not believe the change in your boats performance. I do mean "massive" in the change. You will point much better, you won't be able to tie knots in the leeward shrouds anymore and you will find the "about to break" items in your standing rigging before they gain the 5X increase in price.Enjoy going fast!RayS/V Speedy
