RedactedNarrative: At approximately 10:00 pm on 6/29/2019 the 35ft Cooper started taking on water while at anchor. The owner called Sea Tow for assistance. Sea Tow arrived and transported him to the nearby McDonald's dock and took no further action. He believes that a shaft seal may have been the cause of the leak. The Cooper is not currently fitted with a bilge pump. The next morning at approximately 10:00 am (6/30/2019) he returned and the Cooper was on its side, half full of water. There is NO fuel or oil in vessel. He is currently working on a salvage plan.
