I don't think that's entirely correct. I believe it's not 2 CG captains but rather two people qualified to captain the boat. If it was 2x CG captains it would be a very small subset. I don't think CYOA wishes to make that trip impossible but rather make sure it's safe. I tried to find the rules on their website but I don't see it there. So if you want to go to STX I would think a conversation with them would be the place to start. I was just there a couple of weeks ago and I can attest that it's a great sail and a fun place to hang out. And if you have entered STT following the entry requirements then no other regulations are required for STX.
