Richard, Mike and myself on Hemispheres on an excellent windy day out on the Neuse River. Some damage on that day, the jib car broke through the stopper on the end of the track and was just flying in the air, dangerous. So we hove-to, brought in the genoa and sailed with a full main, doing 7kts. The new PLASTIC stopper only cost $3 for a pair, plus $8 shipping. Go figure.
