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.

You’ll primarily encounter coral reefs during this trip. The staff is excellent. However, the boat can be a bit rough, so if you tend to get seasick, it’s advisable to take Dramamine. Overall, the trip was quite enjoyable.

There is very little seating on the upper deck so if you are prone to motion sickness, there is a good chance you will be standing for the whole trip. I did find a place that worked for me to not be as sick. They are very knowledgeable and very helpful.
