MTB 102 is one of the few surviving motor torpedo boats that served with the Coastal Forces of the Royal Navy in the Second World War.

She was launched and completed at Portsmouth in 1937, bought by the Admiralty, and taken into service with the Royal Navy as MTB 102, the 100 series denoting a prototype vessel.

Besides the torpedo tubes she was built with, depth charges, machine guns, and the Swiss Oerlikon 20 mm anti-aircraft cannon were all tested on her.

In April 1966, in an unseaworthy condition and partially converted into a houseboat, Derek Brown bought her from Robinson's boatyard Oulton Broad.

The original Italian Isotta Fraschini engines became difficult to maintain during the early part of the war as Italy allied with Germany.
