check the end bolts at the outboard end of the track. They were tapped and screwed in on the one I got, and on day three of sailing with it, it stripped and the car came off of the track and through a brand new jib. The jib was replaced and I thru-bolted the end screw on each side, and have no complaints! A really easy fix for a potential problem that could be avoided. Not sure if this is a specific problem to me, or if it has happened to anyone else.
