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.

Ponquogue

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.


Aids to Navigation

Shipping Lanes & Lighthouses

The US Coast Guard maintains a number of aids to navigation to assist vessels entering and leaving ports, both great ports like New York and Philadelphia, and minor ports like Shark River and Montauk. At sea, these aids take the form of buoys that mark out channels and shipping lanes. The chart about also marks major ocean-side lighthouses and a few others. All of these are still extant and may be visited except Shinnecock, which was torn down.

Shipping lanes are like divided highways at sea. Inbound and outbound lanes are separated by a wide "Separation Zone, " which may or may not be depicted on the charts in this website, depending on the scale. Ships "drive on the right" just like cars in civilized countries. At the inbound end where all the lanes converge into the harbor channel, things get messy, and I didn't try to depict it. Likewise, the outer ends of the lanes are not exact either.
