We were sailing our 30' Catalina a few days ago in 15-20 knot winds, when I noticed the leeward shroud seemed to be very loose, with no force on it whatsoever. Of course the windward shroud was very tight since it was holding most of the force put on by the sails. Is it usual for the shroud to be so loose, so loose that i could move it 2'' either way without puting any force on it? When we took down the sails and headed back to port, both shrouds seemed tight as usual. If this is not normal, what should I do to fix it ? Thanks, Michael
