Vessel was travelling at a high rate of speed and there were also ground swells about 3 ft high according to a witness.  Vessel was bouncing around alot and came out of the water 6-8 feet.  Vessel came down onto a swell and split immediately into a v-shape in the middle of the vessel.  2 occupants were thrown into the water and assisted by and put onto other vessels in the area.  One passenger was unconscious and unresponsive was pronounced dead at the hosptial and the other was also  injured.  The investigator determined that cause of accident was many factors.  Unfortunately due to the severity of the break in the vessel - many parts of the motor and vessel were not recovered.  Factors are overall age of vessel and deterioration of internal portions of structure (hull).  Modifying vessel to convert it from inboard engines to outboard.  Increasing outboard hp to 600hp.  Sea state.  Reckless and negligent operation taking into account time of day, number of vessels in area, and restrictions marked by navigational aids.  Alcohol was .08bac.
