RedactedNarrative: Vessel 1 (V1) was at anchor at the above listed location.  The owner noticed the vessel was taking on water.  As OWNER untied the anchor, the vessel rolled over and capsized.  OWNER jumped off the vessel prior to it capsizing. As the vessel capsized, two others were caught under the vessel, but were able to escape.  A good samaritan picked up the occupants and transported them to the Gandy Boat Ramp. Tampa Fire Rescue (Fire Boat 19) recovered the vessel and towed it to the Gandy Boat Ramp .The vessel was removed from the water and placed on a trailer. I took photographs of the vessel. 
  
  I observed that there was damage on the right side of the transom just below the Hull Identification Numbers (HIN). The fiberglass was flared outward. There were two screw holes near the damaged fiberglass. Further inquiry revealed that a ladder was located in this area.  Upon further inspection, there was an opening in the fiberglass below the normal waterline.
