Our party highly recommends Quiescence (hereafter Q) and Capt. Ryan in particular for snorkeling the Key Largo reefs.
I called Q because they have a limit of six people per boat and as a frequent visitor to the Keys I wanted a trip that would go where I wanted to go. We picked a day that he weather was nearly flat calm with the hope of going to Molasses Reef. When you've been to Grecian Rocks (the default site for Pennycamp boats) a couple of times you hope never to be stuck on a boat going there again. The personable Q employee I spoke with on the phone before making my reservation assured me that my party of five would have a lot of input. I called for a reservation with my credit card the day before we wanted to go. This will not work if you want to go during high season! We visited in late August. Be aware that Q has a 48 hour cancellation policy, and ask them what that entails. Also ask about the weather policy. When we arrived 30 minutes early for our tour the counter help was efficient and polite. We took care of paperwork and waited for the boat to return from the morning tour.
The morning group had a delay in getting underway, some late arriving guests, we were told. The boat returned about 30 minutes late, which meant they didn't have their trip cut short, and I was assured that ours wouldn't be either. Capt Ryan gave us a safety briefing on the way out of the harbor. He has a background as a marine science teacher and was a delightful asset for our trip. In about forty minutes we were on the edge of Molasses and gettting in the water. Capt Ryan prepared us for the currents that affect that spot, told us to swim upcurrent past the boat so that if we tired we could just drop back down to the boat. After 10 minutes I noticed my wife, who's shoulder isn't strong, was happily hanging on the end of the safety bouy line behind the boat and asked Capt Ryan if we could move to a spot with less current. No problem. The other side of Molasses was better current-wise. After about 45 minutes there we asked the captain to suggest a shallower reef and he took us to nearby White Banks, where the brain corals are amazing, the largest about 8' high and wide. We were in the water for about 2.5 hours all told, a trip that cost us $49 each plus tax and tip. You can spend $15 less on a "cattle boat" but the extra value of personal attention and Capt Ryan's superior service was worth every extra dollar.
Since this is a review of the people at Q I don't want to spend your time enumerating the species we saw, but do go to Reef.org if you want to see the entire cast of this or any reef. Very handy. Briefly, we saw a huge grouper, lots of barracuda, at least three docile nurse sharks, a big permit, a turtle, a supermale rainbow parrotfish and other reef fish galore, maybe 35 species in all.
