MTB 102 is one of few surviving motor torpedo boats that served with the Coastal Forces of the Royal Navy in the Second World War. She was built as the Vosper Private Venture Boat as a prototype, but was purchased and taken into service by the Admiralty.
She was the smallest vessel to ever serve as a flagship for the Royal Navy.
Designed by Commander Peter Du Cane CBE, the Managing Director of Vosper Ltd, in 1936. She was completed and launched in 1937, she was bought by the Admiralty and taken into service with the Royal Navy as MTB 102, the 100 prefix denoting a prototype vessel.
MTB 102 was the fastest wartime British naval vessel in service at 48 knots.
From 1939 to 1940 she was stationed in the English Channel. During Operation Dynamo (the evacuation from Dunkirk, May–June 1940) she crossed the channel eight times and acted as flagship for Rear Admiral Wake-Walker when his flagship, destroyer HMS Keith, was disabled.
In 1943 she was part of 615 Water Transport Company RASC and was renamed Vimy.
MTB 102 was sold off after the war, and converted to a private motor cruiser on the North Sea.
In April 1966 she was bought from Robinson's boatyard Oulton Broad by Mr Derek Brown from where she was berthed in a very unseaworthy condition and had been partially converted into a houseboat. Single-handedly Mr Brown completed extensive work and proceeded to launch MTB 102.
In 1973 she was acquired by a Norfolk Scout Group, the 1st Blofield and Brundall Sea Scouts, in whose care she remained until 1995 when ownership passed to the MTB102 Trust. The vessel came with the purchase of the plot of land used as the group's water-base on Hobros Dyke at Brundall Marina.
In 1983 and 1990 extensive structural repair work was carried out on the hull and decks totalling around £70,000 .
Several changes of engines have occurred over her life. The original Italian Isotta Fraschini engines became difficult to maintain during the early part of the war as Italy was allied to Germany, though they lasted until replaced after the war when MTB 102 was converted to civilian use. In 1985 Perkins Ltd donated two turbocharged diesel engines, and in 1996 and 2002 Cummins Marine provided new engines.
