When crossing boating channels stay in close groups and cross at right angles. Make yourself visible and never assume a larger vessel has sighted your vessel or that you have the right of way.
Throughout most of the year the prevailing winds blow out of the southwest. The average tidal range in the Norwalk Islands area is 7.5 feet. Each tidal cycle (from low to high) has a duration of approximately 6 hours. Tidal currents are strongest on the mid-outgoing and mid-incoming tides and are more intense during foul weather conditions. Strong tidal currents can be felt between Shea Island and Chimon Island, and the sheer force of their flow can also cause difficult eddy and wave conditions, even on calm days.
When fog occurs, it can result in sudden and total disorientation. You will need a compass, but you may gain orientation from the sound of bells or foghorns as well as steady wave and wind direction. If fog or heavy rain sets in and the shore cannot be seen from the islands, heading in a northerly direction gets you to the mainland.
Please do not tamper with lobster pot buoys or shellfish bed stakes: the shellfish industry is a very important component of the local and state economy.
