RedactedNarrative: Subject, along with friends and family, rented a vessel and were heading to Key Largo Dry Rocks to snorkel. Once out of south sound creek, Subject and his wife realized the vessel was taking on water.  Subject turned on the bilge pumps but stated they did not work. Subject had everyone put on a personal flotation device (PFD) and told them to jump off the boat. The boat capsized and all persons on board were taken by USCG to John Pennekamp Coral Reef State Park.  One person received treatment at Mariners Hospital; he had muscle sprain to his right shoulder from trying to hold on to the vessel while it was sinking.
