The origin of the letters "TID" remains unresolved.
When purchasing TID 164, Martin Stevens was given access to the Ministry of Defence records at Bath, Somerset, relating to TIDs. He came across several 'official' versions to explain the letters T.I.D.
and many others since:-
Towing Invasion Duties
Tug Invasion Duty
Tug Inshore Defence
Tug Inshore Duties
Tug Inshore and Dock
Tug In Dock
Tug Intermediate Design
Tug Inland Distribution
Temporary Invasion Design
- or just nicknamed "Tiddler" in the shipyard.
T.Y.P .... Take Your Pick !
