We took a snorkeling excursion a couple in 2011 from Cancun to Puerto Morelos. I thought it was excelent, the wife, not so much. The waves were more than she was liking and getting in and out of the boats were not easy for her. She also wasn't big on the fact that they were small flat bottom boats with a 5 gallon pail for fuel with a gas line sticking in it from the motor. LOL. Does anyone know if there are any other types of snorkel boats out of Puerto Morelos such as catamaran sails?
