Automatic flashing buoys wil replace lightships to provide navigation aid to marine vessels.
The Arklow light vessel has protected shipping from dangerous submerged sandbanks off the north east coast of Wexford for over a century. It has now been replaced by a LANBY (Large Automatic Navigation Buoy), which measures 40 feet in diameter and is equipped with electric fog signals and radar reflectors.
Captain Herbert Greenlee, Inspector of Irish Lights, outlines some of the features of the new LANBY.
The LANBYs have a very powerful light. They have a fog signal which runs continuously day and night.
The large automatic navigation buoys have a nominal light range of 22 miles. He is confident that the new devices can withstand the rough Irish seas and weather conditions.
