Over tension probably wouldn't break or bend anything but would make the top of the sail "Hook" . A lousy thing for sailing! You're right. It probably won't break or bend anything. Unfortunately, "probably" isn't good enough when it comes to keeping the rig intact. A rig with a 65% chance of making it through the afternoon will "probably" make it, but I wouldn't count on it. An overtensioned vang can definitely shear off a gooseneck - especially if you've wanked down hard on the vang to depower while going upwind and forget to let it off when you bear off to a run. When you're sheeted in, the force on the goosneck is mostly compression; bear off to a run and the force is shear. You see this failure on dinghys that have had the vang upgraded from a stock 3-1 or 4-1 to a 15-1 or 16-1 without upgrading the gooseneck as well. -- //-Walt // // http://cagle.slate.msn.com/working/040514/matson.gif |
