Novice sailer here... I recently purchase a used G-cat 5.0.

I am missing the end cap on the traveler on the back of the boat, the place where the boom is attached and it glides back and forth from port to starboard. Without this end cap the boom just flies off the traveler. Anyone know what size end cap I need? Are they all pretty standard size? Are the Gcat end pieces the same size at a hobie 16?

Also, any suggestions on what rope to buy to flip it back over in case we capsize?
