For clarification, you will not see any inflatable dive boats in Cozumel. They are all fiberglass or wood.
The picture on their pricing page is an interior view of the set-up if that is the picture you are referring to.
The "Bonita Luna" is a 28 - 30' open fiberglass casket boat with a canopy covering the entire diver seating area. It is nice and wide so 6 divers are very comfortable on the boat with room for the crew to pass through. They have brand new twin Yamaha 85's, cushioned flooring, secure tank racks, and ample storage for diver's personal belongings.
I work very closely with Liquid Blue because I have a very high level of respect for Roberto and Michaela and we have the same service philosophies and standards. The main difference is that they use the larger steel tanks, and we use standard AL 80 or AL 100 tanks.
I highly recommend them and you will not go wrong in choosing them!
