Great crew with Captain Katie, Dive Master Allison, and Guide and Dive Master Jim. Captain slowed and stopped boat to observe pod of dolphins and multiple turtles on the way out and back. Jim did a great job in finding and pointing out fish. Conditions were great with no current and waves. Like diving in a swimming pool. Multiple tropical fish. Saw Caribbean reef shark.
