Rumor on the local boating Facebook page is the owner had a heart attack or some other issue that prevented him from pulling the boat. Unfortunately it seems to happen to a few boats a year down there. Usually someone trying to avoid paying for a slip at a marina ties to the wall, then something breaks and they can’t get it towed. Eventually the battery can’t keep up with the bilge pump and it sinks. The city removes it and tries and fails to collect removal fees from the owner. Eventually the city will put a stop to people docking there.
