Apparently the British were pioneers when it came to unmanned vessels,at the time termed ‘crewless’ light vessels, from the early 1900s.
Crewless vessels were used on the Scottish OTTER ROCK, SKEIRINOE and CASH SGEIR stations from 1901-06 which were built by the Clyde Shipbuilding and Engineering Co. Ltd.
