RedactedNarrative: Vessel 1, a recreational fishing vessel, was operating at approximately 31 mph ocean side near channel markers six and seven in the Boca Chica channel when the vessel's starboard hull dug in.  
  
  The operator then pulled back the throttles and the vessel rolled to port capsizing in approximately nine feet of water.
  
  The operator stated in his sworn statement that the starboard hull of the catamaran “dug in” while entering the channel.  While speaking with him he also added that he had been manipulating the engine trim switches and when he felt it was getting worse, he pulled back both engine throttles to neutral and the boat rolled to port with the gunwale being overcome with water and the boat capsizing to port.  The picture of the vessel’s engines while capsized after it was towed to Robbie’s Marina show a major difference in the engine trim levels of the outboard motors.
  
  No electronic evidence was collected due to the vessel being under water.  Weather and sea conditions were not a contributing factor to this accident.  The sea condition were slightly choppy at the entrance to the channel, but not a factor. The wind was around 10 MPH from the south east.
  
  The vessel was completely sunk upon my arrival. The top was torn off during recovery and the hatches were open and the entire vessel was full of water. The condition of the vessel made it imposable to determine if there was a breach in the hull or flooding prior to the accident.
