RedactedNarrative: V1 WAS TRAVELING SOUTH ON THE ST JOHNS RIVER RUNNING ON ONE MOTOR (PORT).  V1 WAS ON PLANE AT APPROXIMATELY 25 MPH.  THE OPERATOR STEPPED AWAY FROM THE WHEEL TO HAND A BLANKET TO AN OCCUPANT SEATED AT THE STERN OF THE VESSEL.  THE VESSEL'S TRACK DRIFTED TOWARDS THE WEST BANK.  THE OPERATOR RUSHED BACK TO THE CONTROLS AND ATTEMPTED A HARD LEFT TURN, BUT FAILED TO CLEAR THE BULKHEAD.  V1 STRUCK THE BULKHEAD ON THE STARBOARD BOW AREA AND IMMEDIATELY WENT INTO A SHARP LEFT TURN.  V1 CONTINUED ITS TURN AND COLLIDED WITH A FUEL DOCK, CAUSING THE VESSEL TO PITCH UPWARD AND DIPPING THE STERN OF THE VESSEL UNDER WATER.  V1 QUICKLY TOOK ON WATER AND CAPSIZED AT THE DOCK.
