Tug, Inshore and Dock (TID) was a standardized British design for a tugboat drawn up and built during the Second World War.
One hundred and eighty two (TID-1 to TID-183) were built for the Ministry of War Transport.
As designed they were 65 feet long by 17 feet in the beam by 8 feet deep, measuring 54 GRT. Draught when laden was 7 ft 4 inches - a displacement of 124 tons. Propulsion was a 220 ihp 2 cylinder reciprocating steam engine driving a single screw. Steam was from coal or later oil - the change being to allow use in the Far East. They were capable of 8 and a half knots.
The hulls were built as eight separate sections by a group of manufacturers with spare welding capacity - normal British boat construction being riveted - building capacity was in short supply at shipbuilders but other non-shipbuilding industry was available. These 6 ton sections were transported by road or rail to the shipbuilder for assembly and fitting out. Production was fast at about one hull every five days.
