Long Island has many great sites for shore diving. Listed here are just a few for which I have scavenged descriptions. For a complete listing, pick up a copy of Dan Berg's Long Island Shore Diver at your local dive shop.
Do not ask for numbers - I will not give them out !
March 1, 1902; ran aground in storm - no casualties
Depth:
25 ft
The Acara lies 1,500 to 1,800 ft offshore, in 25 ft of water. She is quite broken up, with wreckage spread over a wide area. Still, there are one or two sections with 10 feet or so of relief. Brass fittings and other artifacts are still being found.
The visibility on this site varies. Average is 10-12ft. This site offers two wrecks which lie in 25 fsw. A British WWI two-man reconnaissance submarine and an old wooden barge. They are both within swimming distance from each other. The marine life is fair around these wrecks. There are a few car tires between the two wrecks and you may find an occasional lobster hiding inside them. To locate the barge take a compass heading of 330 degrees from the pilings located on the east side of Greenwich Ave. It takes about 50 kick cycles to reach the wreck. To get to the submarine take a compass heading of 30 degrees from the same pilings. This can be reached in about 30 kick cycles. Both of the wrecks are not intact but make for a good dive.
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.
There are two actual Ponquoque bridges, the new one and the old one. You crossed the new bridge to get to the former Foster Road. The old bridge is where you will probably dive, although nothing is stopping you from diving the new bridge. Don't get caught in the channel between the two bridges, however, because it is considered a channel and it is illegal to dive in a channel in the town of Southampton. With that in mind, there is usually good parking at the bridge, but you will have to do some walking in order to get into the water.
