No just on the beach 3 different sizes all coast guard approved ones. Before you snorkel off the catamaran they do give you a snorkel life vest the blow up kind.Do they have e life jackets for the kids to wear on the catamaran? We are used to lake boating and the kids always wear a life jacket from the dock to the boat and while we are on the boat. I’m not sure how it works with a catamaran-sized boat.
