 The visual similarity between Skerryvore and Dubh Artach 20 miles ( 32 kilometres ) to the south east , led to the NLB painting a distinctive red band round the middle section of the latter in 1890 . The Hynish Shore Station had the advantage of proximity to the site during the construction period . However the small harbour offered little shelter for shipping . The keepers operated from here until 1892 when operations were transferred to Erraid adjacent to the Isle of Mull . Other than the signal tower , the land and buildings on Tiree were sold to George Campbell , 8th Duke of Argyll who had witnessed the laying of the first stone on Skerryvore fifty @-@ two years previously . A paddle steamer , Signal , built by Laird of Greenock in 1883 was based at Erraid for relief operations . The shore station was moved to Oban in the 1950s .
