RedactedNarrative: On Monday, March 29, 2021, at approximately 0500 hours, Ocean Yacht vessel struck the ground inside navigational channel.  There were 4 people on board; 2 of them sustained injuries and were admitted to hospital for treatment.
  
  Vessel, later identified as DO1060022, 1998, 48-feet, Ocean Yacht was grounded inside the navigational channel between red markers 10 and 8A.  Vessel owner/operator and three passengers were departing for a fishing trip.  Operator and Occupant1 were navigating from top of the bridge, Occupant2 and Occupant3 were inside the cabin. 
  
  Operator told me, they left at approximately 0445 hours.  He was operating the vessel from the bridge, at approximately 15 knots.  Due to limited visibility, he was inside the channel and navigating from a channel marker to a channel marker.  Suddenly, vessel hit the ground and stopped.
  
  Occupant1, who was also on the bridge, and was using a spotlight to aid navigation, confirmed the sequence of events and operating speed.  Neither of them sustained any injuries.
  
  Occupant2 and Occupant3 were inside the cabin.  Upon impact with the ground and sudden cease of movement, they were thrown forward against the table and a wall. Occupant2 suffered multiple facial fracture and thoracic fracture (see injury supplement).
