RedactedNarrative: V1 was exiting the Sebastian Inlet at approximately 9:30 AM, cruising east towards the Atlantic Ocean. As V1 approached the exit of the inlet, the swells became large due to the wind and tidal current. The operator powered through the rough swells causing the bow of the vessel to rise and fall violently with the wave action. There were five occupants on board (including the operator) and one of the occupants on the bow was holding a large Bluetooth speaker on her lap. This occupant was seated on the deck near the bow and facing the rear of the vessel. As the bow fell after cresting a large wave, the speaker flew up into the air and fell back down striking her in the forehead area. This created a large laceration that began bleeding profusely. The operator then turned V1 around and proceed back into the inlet where he beached the vessel near the Sebastian Inlet boat ramp in order to meet with EMS. The injured occupant was transported by EMS to Sebastian River Medical Center where she received stitches to close the laceration on her forehead.
