December in the Caymans is always iffy with the chance of northers. Our first trip to LC in 2010 the day we arrived boats hadn't been out for three days. We were lucky. The first time out was the next day on our first day of diving. The seas were still rough The diving was excellent . . . until the mooring line broke while in the middle of our second dive. That was an experience trying to recover divers on the drift in high seas and getting close to shore.
