Long Island Sound - West Chart

Long Island Sound - East Chart

Long Island Sound averages 60 ft in depth, with the greatest depth of over 300 ft at the eastern end. Tidal effects are strongest at the narrow western end, where all the inrushing water flow piles up and makes tidal variations of up to 7 ft. Strong tidal currents are also prevalent, and visibility tends to be poorer than the open ocean, especially at depth.

Mount Sinai Harbor

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.

I started this site way back in 1996 for my new hobby. In all that time, I gladly carried the annual cost of hosting and domain name. But it's time to admit that my diving years are over, and my interest has waned.

I have kept the site up as a service to the diving community, but I don't know how much longer that makes sense.

If you would like to make a small donation to help defray that cost, it would be greatly appreciated, and help to keep the site online.
