  On July 29, 2023, vessel 1 was leaving Mosquito bank sandbar in Key Largo, FL. The vessel was operated by OP1 and was heading towards South sound creek. From statements made by the individuals aboard the vessel, the vessel began to sit heavy at the stern. The vessel began to take on water over the stern of the vessel. The passengers checked the bilge pumps to ensure they were functioning. Once the pumps were checked and found to be operational the vessel continued to travel west. The vessel continued to sit lower in the water as the vessel was traveling. The occupants flagged down another vessel and called for assistance. All passengers were transferred to the other vessel. After the transfer was made the vessel took on more water and overturned. The individuals were safely transported back to shore. A commercial salvage company arrived and up righted the vessel and towed it to Caribbean club boat ramp. Once the vessel was on the trailer, I noticed the cap and hull of the vessel was separating. The Gap between the hull and cap of the vessel extended on both the starboard and port side of the vessel. The gap was approximately 2 inches wide. From the statements made and inspecting the vessel after it was recovered, I concluded the vessels cap and hull separating contributed to the capsizing of the vessel. 
  Nothing further
