RedactedNarrative: On the time and date stated above I observed a boat being towed in from the Delaware River into the Delaware City branch Canal to the boat ramp. Upon SeaTow releasing the vessel to the boat ramp to begin loading of the vessel onto the trailer, I went down to the boat ramp to investigate the incident. I met with all occupants on board at the boat ramp. Upon inquiring the status of the vessel I was informed by the operator of the vessel that they had struck the North jetty of pea patch island in between the power lines at 1245hrs at approximately 25mph traveling North East towards the Delaware Memorial Bridge. I then asked if there were any injuries on board in which they replied no one was injured, I then asked if they were taking on any water in which they replied no only damage to the prop as far as they know for now. 
  
  I then conducted a vessel safety inspection in which they had all documents and equipment on board the vessel with easy accessibility. I then informed the owner of the vessel that they can get their vessel on the trailer and once it is out of the water we can then assess the damage to the vessel. Upon inspection of the vessel there was a large quantity of damage done to the 2 props on the inboard engine along with damage to the skeg of the motor. The owner also indicated that the motor will have damage to it as well possibly being the crankshaft due to having no propulsion to the props. I asked if they had any charts on board in which the operator replied he was using the navigation chart on his phone but was not currently looking at it at the time of impact. 
  
  The operator stated that he observed the danger signs around the jetty but believed that the danger area ended at the last danger sign so he went to the left of the danger sign unknowingly going over the north jetty of pea patch island resulting in an impact with the jetty.
  
  They then tossed anchor and called for SeaTow. After gathering all information on the incident I found it reasonable to understand his situation and issued one written warning for Negligent Operation of a Vessel for an improper lookout. I explained to the operator of the vessel the importance of keeping a proper lookout on the water and also the navigation charts.
