  Vessel one (V1) with one operator and 3 passengers was anchored approximately 100 yards northwest of the Howard Franklin Bridge. V1 was anchored from the bow and was turned off. The four persons on board were engaged in fishing when they noticed water inside of V1. Shortly later, V1 rolled to the port side and capsized. All persons on board were ejected. Three of the subjects climbed on the hull of the capsized V1, while the fourth subject swam to the Howard Franklin Bridge and climbed onto a pillar. A vehicle traveling along the Howard Franklin Bridge saw the capsized V1 and reported the incident to Pinellas 911. A multi-agency search and rescue (SAR) ensued. An Officer with the Florida Fish and Wildlife Conservation Commission was the first on scene and rescued the four subjects. 
  
  V1 with operator and passengers departed the Courtney Campbell Causeway boat ramp enroute to the Howard Franklin Bridge. Operator and occupant1 both noticed V1 appeared to be performing poorly, as if it was underpowered. It took longer than normal for V1 to get on plane. V1 arrived at the Howard Franklin Bridge at approximately 15:00. The anchor was set and the four occupants began fishing. 
  Approximately 30 minutes after setting the anchor, all four subjects noticed water filling up the inside of V1. Shortly later V1 began listing to the port, eventually ejecting all four subjects. V1 rolled to the port and capsized. Three people climbed onto the over turned V1. The fourth swam to the Howard Franklin Bridge and climbed onto the pillars. 
  V1 remained afloat, with the majority of the bow out of the water. A vehicle passing by on the Howard Franklin Bridge saw the capsized vessel and reported the incident to Pinellas 911. A multi-agency search and rescue ensued. An officer with the Florida Fish and Wildlife Conservation Commission was the first one on scene. All four subjects were retrieved from the water and transported back to the Courtney Campbell Causeway boat ramp. 
  
  CONCLUSION 
  Based on statements, evidence and information gathered to date, the contributing factor in this accident was a breach in the hull of V1 that had occurred in the past. During an inspection of the hull of V1, I discovered an area on the port side, forward of midship, that appeared to have fiberglass repair. Upon closer inspection I discovered there were several breaches in the hull that would allow water to pass into V1. The breaches in the hull appeared to have been present for quite some time due to the discoloration of the fiberglass.
