Project history: The concept of purpose-built small TBs capable of being lifted by the davits of large ships seems to have originated with the Royal Navy; certainly more were built for that service than for any other. One TB carrier, Vulcan, was specially built to carry them, and for some years numbers of this type of boat were built. However, in the long run experience showed it was better to use the slower but much sturdier and more seaworthy steam pinnaces for this purpose, rather than the frail specially built Second Class boats.
TB100 was fitted with one of the earliest Thornycroft water-tube boilers, whilst her sister still had a locomotive boiler. It was on these boats that the Thomycroft 'semi-tunnel' stern, with double rudders almost enclosing the propeller, was introduced. This gave them very good turning ability.
Modernizations: None.
Naval service: No significant events.
