What a wonderful trip! As a person who has terrible sea sickness, this large catamaran didnāt make me sick! There were about 70 people on our trip but the boat was big enough that you didnāt feel like sardines in a can. It takes about an hour to get out to the reef and you get an hour to swim around. Saw a puffer fish, yellowfin, parrot fish and others I couldnāt identify. The crew was amazing and attentive.
