RedactedNarrative: On June 28, 2015, the Grand National Class Hydroplane (GNH) THIS IS HEAVEN - GNH-12 was participating in a hydroplane boat race with three other GNH participants.  The Thunder on the Narrows power boat race is sanctioned by the American Power Boat Association (APBA) held at Prospect Bay near Kent Island, MD. The annual power boat race is permitted by USCG and sponsored by the Kent Narrows Racing Association. While rounding turn one during the 5 minute period prior to the official start of heat 1, GNH-12 slowed down and veered to the right towards the outside of the race course.  This movement allowed three qualified drivers to pass on his inside to obtain inside position for the official start of the race. 
  
  As GNH-12 slowed down, the operators vision was obstructed when water began to spray over the port sponson and onto the windshield of the canopy. Unable to locate the hydroplanes passing on his inside, the operator maintained a starboard course to stay clear of the other racers and in the direction of recreational vessels. The GNH-12 struck three spectators who were on rafts, and allided with recreational vessel A SHORE THING (MD2223D) stern. Additionally, the impact caused significant damage to A SHORE THING and other recreational vessels. Through a chain reaction, the force of the impact caused A SHORE THING to allide with spectator vessels moored or anchored alongside. Two victims sustained serious injuries and were medevac'd to the University of Maryland Hospital in Baltimore, MD. The third victim was transported to Anne Arundel County hospital by ambulance and was released later that night after sustaining only minor injuries. The fourth victim was transported by ambulance to Queen Anne Emergency Center where she was pronounced dead.
  
  The driver of the hydroplane was a sub; he joined the boat after his own boat became disabled and was unable to operate.  The owner of the involved hydroplane did not inform the driver of oil pressure issues and visibility due to water spray.  The operator was inexperienced with the particular type of boat; he had not been in an enclosed cockpit before.
  
  The hydroplane operator completed one lap and slowed down.  The three other operators caught up to him.  The spray onto his cockpit affected his ability to see.  He maintained speed and veered towards the spectators to stay out of the way of the racers
  
  The deceased and one person had been on an orange inflatable tied to the back of one of the vessels.  They were ejected from the lake.  The injured victim was recovered floating and unconscious; she had head trauma, broken vertebrae and a broken collar bone.  The deceased had been struck by the boat.
  
  An individual on another raft suffered a broken collar bone, multiple broken ribs and lacerations to the eye.
  
  The hydroplane then crashed into A Shore Thing, causing a 5.5 x 2 ft opening in the starboard sponson of the hydroplane and rips the outboard off A Shore Thing.  Debris from this event causes cuts to an occupant of a vessel.
