The HMCS Bras D’Or was the pinnacle of over 100 years of hydrofoil development in Canada. Starting with Alexander Bell and ending with the Proteus, hydrofoils held the promise of faster travel over the waves. Unfortunately the technology never found a comfortable fit in either military or civil fleets. It was designed to be an ASW hunter but by the time she was ready, the Navy was settled on using the now familiar Destroyer/Helicopter combos.
