RedactedNarrative: EPO responded to a report of a vessel that had washed ashore with one person on board. The location was in Jerusalem on the west side of the west wall (jetty). When EPO arrived he observed that the boat (RI 2533P) was aground and the owner/operator seemed disoriented but did not have any injuries. Operator stated that he went fishing and was returning from Block Island. While en route He lost his radar and used his gps to get back to port. Upon arriving at port he hit the west side of the jetty. He soon realized that the water level was shallower and when he tried to turn the boat around, a wave swamped the boat and washed it on shore. The damage sustained to his boat was dents in the hull on the starboard side.
