We had our boat built on the Island by Roberto Canul who sold his business to Capt Sharks.
Sharks does a good job building boats and can even customize if you need something special.
One of our good friends just purchased a new boat a couple of months ago and is quite happy with the workmanship of Capt Sharks.
Ours is a 25ft (50 BZ)

Luna-25 model and has gone around the whole island (in very low water) several times, to Belize City several times and outside the reef Many times. I would have no problem taking it to the blue hole (on a nice day).
