Thanks guys.
Those "some people" are probably monoslug sailors who are just jealous that their boats can't MOUNT the marks and stay there like we can... <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
Proper Mark Mounting = Getting the mark stuck in the square that is formed by the front crossbar, the two hulls and the bridle. Mounting is much easier (and faster) than dismounting...
