The lighthouse was relieved by a local boat from Skerries, or by one of the vessels owned by the Trinity Board, until 1970. From then it was relieved by helicopter.
There were a total of six lightkeepers doing duty on the rock. Three were stationed on the rock doing four weeks duty at a time, while the other three had four weeks liberty. The keepers and their families lived in houses specially built for them in Harbour Road. These houses were sold individually in 1975.
