We departed on time, after some practiced but lively instructions about how to act on the partly open deck boat. Fury has a range of boats. Ours was a half open floor plan ideal for viewing dolphins, with a ladder leading down to water for snorkeling, which comes in the second half of the trip. Some Fury Catermerans have rear steps leading into the water, which could have made for less crowded egress and ingress. Take it from my experience, it's probably not the best idea to be the first one off the boat into the snorkeling area. True, there is less scaring away of fish life by people at that point, but it's hard to clamber back aboard when you realize you should have taken the option to inflate your buoyancy vest before going into the water. I panicked a bit when realizing that breathing through one's nose is not an option with the face mask, even while above water, and it's hard to blow up a vest while panting. Standing on the bottom is possible but strongly discouraged as your oils will kill anything they touch. Bring wave walkers; they do not provide swim fins, no matter what the brochure shows.
We followed a dolphin pod - not a family, since males do not raise dolphin calves - for about 20 minutes. Great leaping! More please. Don't expect Seaworld shows. These are wild dolphins and they're working, not being handed fish from a bucket.
A party atmosphere pertained on the meander back, with "adult juice" served on request; you are not allowed to drink and snorkel. The hosts were great and the rentable wetsuits are recommended especially in the winter when water temps are around 68 degrees. The water was fine, it was chilly when I got out again.
One other thing: we had originally wanted to do the glass bottom tour, but were prevented by the weather, once, twice, then three times, before we took the alternate tour when our days were running out. Check for windy conditions before booking the glass bottom tour.
