RedactedNarrative: I obtained a written statement from Operator that stated he was operating the 40 foot Sea Ray boat from Delray Beach to Key Largo. He was using the auto guidance feature on the GPS. He instructed one of the occupants to keep looking out while he went to the bathroom. Operator verbally stated to me that Occupant didn’t possess enough navigational skills to operate the vessel. As he was heading back to the helm, the boat collided with a navigational aid that he wasn’t aware of. Operator immediately steered the boat towards shore where he observed extensive damage to the starboard side bow and radar tower. 
  
  Operator showed me the GPS route that the auto guidance was navigating at the point of impact. The route is clear of any navigational aid. The GPS route shows the boat pass just to the East of the Navigational Aid at the Miami Main Channel Entrance Range front Light at position N 25. 45. 222 W 080.7.297 where the collision occur. Then the vessel turns to the west towards shore.
  
   I later documented that Vessel 1 was identified as a 40ft Sea Ray named SENSUS VITAE Documented number 1061272.  The vessel had extensive damage on the starboard side Bow and Radar tower. The collision left a large opening on the starboard side bow, visible from the inside of the cabin. The radar tower was partially detach and the front windshield was also damage. 
  
  Based on the GPS route of the vessel, Operator statement and damaged found on the vessel, I conclude that the vessel impacted the Navigational Aid mention above on this report. The data based used by the Auto guidance feature of the vessel may had been incorrect showing the Navigational Aid West of his actual position causing the Collision of the vessel.
