The hydrofoil development work by Saunders Roe in support of the Canadian naval hydrofoil program led to the construction in 1956/57 of the 59 foot long hydrofoil R-103 BRAS D'OR. She was equipped with ladder foils and powered by twin Rolls Royce Griffon engines driving twin contra-rotating propellers at the base of the central 'skeg' via bevel gearboxes. She was launched in May 1957, underwent sea trials on the Menai Strait in May and arrived in Canada in July where she went into the Royal Canadian Navy although never commissioned as a warship. R-103 BRAS D'OR was subsequently re-named BADDECK in 1962 in anticipation of the construction of the proposed larger HMCS Bras d'Or FHE-400 which was to be given the name in the late 1960's.
As R-103 BADDECK she retired from the Canadian Forces in 1973 and was later acquired by the Canadian Science and Technology Museum in Ottawa where she remains in storage without her three foils, central twin propeller skeg or the two Griffon engines. No restoration has yet taken place.
