Encyclopedia
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 8½ 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.

Gross Register Tonnage
Gross register tonnage a ship's total internal volume expressed in "register tons", one of which equals to a volume of . It is calculated from the total permanently enclosed capacity of the vessel. The ship's net register tonnage is obtained by reducing the volume of non-revenue-earning spaces i.e...
