NTM 04/16 East Loch Tarbert, Harris Sgeir Ghlas AtoN Light, A3993, All Sectors Unreliable
Mariners are advised that a recent inspection has discovered inaccuracies in all light sectors of Sgeir Ghlas sector navigation light.
Following an inspection by NLV Pharos it has been reported the southern (seaward) sectors were all found at 1 degree higher than charted while the northern (landward) sectors were 3 degrees higher. This sector light should therefore be considered by mariners to be unreliable.
The small lighthouse on Sgeir Ghlas, near Scalpay, East Loch Tarbert, consists of a stand-alone octagonal shaped concrete tower, which is painted white with a red roof.
