HMCS Fundy (MCB 145) (II).  second of name, had a very brief career under the White Ensign of the Royal Canadian Navy.  She too was a minesweeper but of very different construction to that of her predecessor.  Of the “Bay” Class, the 152-foot ship was built of wood and aluminIum to comply with modern concepts of mine warfare.  Built at Saint John, N.B., she was commissioned there on 19 March, 1954.  HMCS Fundy sailed to Halifax and there joined the First Canadian Minesweeping Squadron.  However, her pennants, MCB-145, were not to be seen for long in Canadian waters.

In compliance with Canadian foreign policy of mutual aid to our partners in the North Atlantic Treaty Organization, HMCS Fundy (MCB 145), together with other ships of her class, was transferred to France.  At Halifax on 7 April after only eighteen days service, the French Tricolour was hoisted in HMCS Fundy and she was given her new name La Dunkerquoise.

The vacuum ship YBZ-61 at work alongside the HMCS Stettler (FFE 311) in 1964.  The YBZ-61 was, in effect, a huge vacuum cleaner whose job was to vent, clean and gas-free the fuel tanks and bilges of warships.  She not only saved time, man hours and money, but made a messy and unpleasant job much easier to tackle.
