RedactedNarrative: On 6/11/18 at around 1230 hours, Vessel 1 attempted to get on a plane and the vessel would not get on a plane as it was stern heavy. The port motor was not running correctly due to a fuel issue. The operator reduced power and noticed water in cabin of vessel and over vessel batteries. Took waves over stern of vessel as vessels stern was becoming lower in the water.  At this time captain attempted to activate spare portable bilge pump but was unable to safely attach pump to submerged batteries. Occupants of vessel then put on life vests and utilize visual distress signals. A mayday call was placed on VHF 16 by the captain. Captain dropped anchor which was attached to bow of vessel. Good samaritan vessels were on scene shortly and removed passengers and the captain from the vessel. All occupants of vessel 1 were uninjured and transported by good samartian vessel to Carrabelle.
  
  On 6/16/18 I received a phone call from Operator 1 regarding his vessel. In an attempt to determine the cause of his vessel taking on water subject filled the vessel's bilge with water and did not observe any leaks in the hull. Operator 1 then told me from the outside of the vessel he placed a water hose into one of the below the waterline through hull fittings near the bow of the vessel, and while inside the vessel's cabin area he could see water entering the vessel's bilge. This through hull fitting is believed to be the cause of the vessel taking on water and subsequently sinking.
