RedactedNarrative: The vessel capsized a half mile south of Hopkins Island. 
  
  The subjects advised me that two people were standing on the back of the vessel fishing while two others were spearfishing in the water. Approximately 15 minutes had past and the two subjects noticed that the vessel was taking on water fast. They moved their gear to the front of the vessel. The vessel then capsized and the subjects waved down a nearby boater who gave them life jackets. 
  
  Tow Boat US responded to the capsized vessel and towed it to the Wharf Bar and Grill boat ramp. The tow boat operator,  advised that when he righted the vessel, the automatic bilge pump was not on. He turned the bilge pump on manually. 
  
  An employee of Keys Boat Rental, stated that he reviewed all of the safety equipment on board the vessel with the renters. He then showed them were the bilge pump switch is and turned it on for them.
