Navigational Hazards
-------------------------

Salmon nets are a hazard and can be found on the north coast west of Lough Foyle, and along the South coast. Usually these nets run out perpendicular from the shore with a buoy at the outer end and a fishing somewhere in the vicinity - typically near the inner end. In between are tiny floats a few inches along strung along the top edge of the monofilament net - not easy to spot. Checking ahead with binoculars for a buoy and a fishing boat is recommended, when you may be able to alter course early. If you happen to spot a net close ahead, alter course to seaward and continue until you spot is buoyed termination. Nets may also be laid in the mouths of estuaries - the ICC directions lists places where they are most likely to be encountered.
