Boatswain's Call

A boatswain's call, pipe or bosun's whistle is a pipe or a non-diaphragm type whistle used on naval ships by a boatswain. It is pronounced, and sometimes spelled, "bosun's call".

The pipe consists of a narrow tube (the gun) which directs air over a metal sphere (the buoy) with a hole in the top. The player opens and closes the hand over the hole to change the pitch. The rest of the pipe consists of a 'keel', a flat piece of metal beneath the gun that holds the call together, and the 'shackle', a keyring that connects a long silver or brass chain that sits around the collar, when in ceremonial uniform.

Famous quotes containing the words boatswain and/or call:

    The master, the swabber, the boatswain and I,
    The gunner and his mate,
    Loved Mall, Meg, and Marian and Margery,
    But none of us cared for Kate;
    For she had a tongue with a tang,
    Would cry to a sailor, ‘Go hang!’
    She loved not the savour of tar nor of pitch,
    Yet a tailor might scratch her where’er she did itch:
    Then to sea, boys, and let her go hang.
    William Shakespeare (1564–1616)

    The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run.
    Henry David Thoreau (1817–1862)
