This unknown vessel is listed on the charts as "Margaret" and is speculated to be a tugboat. She may be the remains of the Margaret Olsen, a small steam-driven harbor boat, which collided with the tugboat Joseph A. Ginder on May 4, 1929. Visibility is usually pretty poor, 15 ft or less, and current can be a problem, due to the proximity to Deb's Inlet.
Once you get there, suit up at your car and walk down the small stretch of beach till you get near the jetty. Enter the water at your leisure. Once in the water, you can swim north along the jetty to the tip. You may see fish, lobster, crabs and the sort. There are large openings in the rocks that form the jetty. Large enough in fact that you can almost swim into one. I don't advise doing this because getting stuck might be a frightening experience.
Deep and dark, the Mud Hole is the Hudson River's channel from a time when the oceans were much lower. Today it collects all the silt and sediment that the river carries out to the sea, making it a very fertile fishing ground, frequented by pelagic fishes and sharks.
Probably so-named because it is the next-closest thing to the Pinta at the same depth. So if that wreck turns out to be occupied by another boat, you get a "New Deal". Seldom visited, so should be good for fish and lobsters. A large and relatively intact barge filled with stones. Known by many other names, depending on who you ask.
The Irma C, an old coal barge, rests a few miles east of the G&D wreck. Her remains have been reduced to a small low-lying patch of wreckage, so that fishing or dive boats may find it a little tricky to anchor on her.
