RedactedNarrative: On 10/06/2022 Operator was operating his 37 foot sailboat in the Delaware River in the area of Bayview Beach. Operator had left Cape May, NJ at approximately 1020 hours and was travelling North towards the anchorage area in the Delaware River just South of the C and D Canal. Operator was travelling North on the East side of the Reedy Island Jetty. Operator said he was travelling under power from his 36 HP Yamar inboard/outboard motor at approximately 6 to 6.5 knots. Operator said he had cleared the dredge equipment to his left and at approximately 1910 hours he struck the jetty. Operator stated that he did not have any electronic failures and was not confident in the colors of the nighttime mode of his GPS maps. Operator also advised that he had been sailing for 21 years. Operator showed myself and Cpl 2 his GPS track on his phone. At this time, Operator stated that the jetty was not labelled. Cpl 2 pointed out a yellow line that ran the length of the jetty that had several other markers indicating danger as well. Operator again explained he was not confident with the nighttime mode of the GPS. Operator stated that he called the USCG for help due to his sailboat taking on water. He stated that another sailboat nearby launched their rescue vessel to bring Operator a pump. Operator advised that the water in the vessel was over the floorboard and the floor boards were floating. Several fire departments arrived on scene and were able to assist with pumping out the water from the vessel. The fire vessels helped to free Operator's sailboat from on top of the rock wall and once free SeaTow towed the vessel to Delaware City Marina where it was removed from the water and inspected for damage. Operator estimated approximately 10,000 dollars USCG worth of damage was done to the vessel due to the cracks in the fiberglass and keel damage. Operator had all Navigation lights functioning and on as well as all of his safety equipment on board. Operator was issued a citation for Negligent Operation of a Vessel (99:23:3100:0711) and given my contact information for any further questions.
