HMCS Ojibwa Bell
It has been tradition, for centuries, to baptize children using the ship’s bell as the baptismal font. The child’s name was usually engraved somewhere on the bell, usually inside the mouth. Canadian submarines have maintained that tradition.
During the baptismal ceremony, the bell is inverted in its box and filled with water used for the blessing. On completion of the baptism, the water is ceremoniously poured over the side. That ritual is marked by piping the still and the carry on with a bos’n’s call.
