A small commercial fishing vessel of unknown type, although the bushels on deck would imply that she was after some kind of shellfish.
There are three basic types of commercial fishing vessels found in the Mid-Atlantic region: trawlers, seiners/gill-netters, and long-liners. A trawler or "dragger" operates by towing its fishing gear across the bottom. Weighted nets take bottom fishes, while cage-like steel dredges take clams and scallops. A seiner uses a floating net to encircle schools of surface-swimming fishes such as herring and tuna. A long-liner sets out miles of buoyed line with baited hooks to catch sharks, tuna, and swordfish. One could also add lobster boats and charter fishing or "head" boats to this list. And of course, dive boats.
View of the up-river area, looking southeast. Either side is diveable upstream to the first road. The entry location is just to the right of the apartments.
Yet another place to dive the Shark River is on the south side, near the intersection of 1st Avenue and A Street, behind the apartments. There is limited but very convenient free parking. A small cement stairway leads down to a concrete ledge above the water. Climb down between the big rock and the bulkhead, where you will find more steps underwater.
