Florida Keys
From our sun deck, you will have a panoramic offshore view of the Florida Keys and can view the ever-changing colors of the Atlantic Ocean. Once we reach the reef, you will be able to observe the coral reef through our large viewing windows, which are large enough for everyone to observe the reef at the same time and are located along the center of the boat and installed flat so there is no distortion other than what nature creates. Everything you see on our tour is or was alive and the reef itself is built off of many varieties of living coral and teems with an assortment of sea life. Your tour guide will be able to point out all kinds of sea creatures which may include sea fans, sea plumes and hundreds of fish ranging from small tropical to larger species sought after by local fishermen.

Enjoyed the experience. The boat was clean and well cared for and crew were terrific. The boat has plenty of cover from the strong Keys sun on both decks. We happened to have perfect weather with mild weather and smooth seas. Viewing of the reefs was through the hull windows was interesting. The water was very clear. Not the same as being among the corals and fish, but not bad for the money.

I wish I could give this a rating but it was canceled the morning of the trip due to high winds. Disappointing. We were leaving area so couldn’t reschedule.
