We did this on the 7/5 also. The reason it's called "Seahorse" is because the boat is named "Seahorse" just like the "Fury" is not relative to ocean condition but named because of the boat "Fury", etc. We were on the morning excursion which like others have pointed out the water was very choppy - the current caused some weaker swimmers to struggle a bit. The reef was absolutely beautiful - filled with ocean critters (except those cute seahorses) even saw some squid. The coral was awesome. The afternoon boat went to a different location because the storm was pushing closer to the area we had been in earlier that day. Drinks were all included (alcoholic ones, too). The crew was very friendly, helpful, courteous, but definitely not experienced. The captain chugged us out to the reef so fast I think it caught some by surprised, but the water was not exactly calm. Anyway I thought it was a nice alternative to CC, but then this was our third cruise and we were kinda bored with the same ole snorkeling path...
