DEP: CT Tides and Currents

The mariner should be familiar with the effects of the tides and currents in Long Island Sound. This body of water rises and falls every 12 hours, and vast amounts of water move through places like Race Point on the western tip of Fisher's Island, Plum Gut on Long Island and Hells Gate in New York on the western end of the Sound.

Strong winds accompanying a tide in the same general direction would tend to increase the tidal effect. Conversely, a tide flowing against a strong wind would be diminished in effect. It should be noted, though, that a strong wind contrary to a tide can create a hazardous condition with steep and confused waves.
