On This Day in Trinity House History – 15 April

THV Alert is Lost During the First World War

The Corporation’s steam vessel THV Alert was sunk near Dover, with the loss of eleven lives, after contact with a mine when on special service.

THV Alert was the second of her name to serve Trinity House as a tender, built in 1911.

She was replaced by the Argus from Yarmouth; in order to carry on the work in that district a new trawler, on the stocks at Selby, was requisitioned and fitted for handling buoys. Her original name Jeria was retained.

She carried out her work satisfactorily until the end of the war; the crew spoke highly of her seagoing qualities. The Admiralty replaced Alert with a duplicate vessel in 1920 from the same builders, Messrs Ramage and Ferguson of Leith; she would also be sunk by a mine in the Second World War.

Trinity House Lays the First of the Modern IALA Buoys

THV Ready had the honour of laying the first IALA buoy in a ceremony off Dover, watched over by representatives of 16 nations.

The IALA (International Association of Lighthouse Authorities) Maritime Buoyage System was implemented in 1977 to address the unsatisfactory and sometimes disastrous mix of over 30 buoyage systems being used worldwide. IALA first set up an international technical committee in 1965 to examine the problem and design a system that would be globally recognised. Trinity House played a leading part in the system’s successful deployment, with an Elder Brother chairing the committee.
