Unique to naval life, are the pipes that are made by the boatswain's call.
Piping is the Naval method of passing orders and every seaman should know how to use a "boatswain's call". The use of the bosun's call goes as far back as the Crusades (1248).
In former days it was worn in English ships as a badge of rank, because it was always used for passing orders. For years it was even worn as a badge of office os the Lord High Admiral of England and his successors up to 1562. Thereafter it was used in the English fleet for passing all orders and since 1671 it became generally known as the "boatswain's call".
Nowadays the boatswain's call and chain are the badge of office of the Chief Boatswain's Mate, the Quartermaster and Boatswain's Mates. The expression "To Pipe" means, to sound on the boatswain's call and the spoken order to qualify it. Some "Pipes" are even orders and do not require any verbal qualification.
boatswain's call is held in the hand between the index finger and
thumb, the latter being on or near the shackle. The side of the
buoy rests against the palm of the hand. The fingers close over
the gun and buoy hole in such a position as to be able to throttle
the exit of air from the buoy to the desired amount. Care must be
taken that the fingers do not touch the edge of the hole in the
buoy, or over the hole in the end of the gun, otherwise all sound
will be completely choked.
bosun's call can be tuned by scraping away and enlarging the wind
edge of the hole
in the buoy and it will sound if the mouth of the gun is held directly into a moderate wind.
are two main notes; the low and the high, and three tones; the plain,
and the trill.
following instructions show the various pipes used in the Canadian
Navy. The numbers at the top of each figure represents seconds of
time. The nature, continuity and tone of the notes are indicated
by the various lines, and the degree of their slope indicates the
speed of ascent or descent of the notes.
The still is used to call all hands to attention as a mark of respect, or to order silence on any occasion. The still is also used to announce the arrival onboard of a senior Officer. The pipe is an order in itself and does not require any verbal addition. The still is a high note held for 8 seconds. If done properly, it should end very abruptly.
The carry on is used to negate the still. The pipe is an order in itself and does not require any verbal addition.
The general call precedes any broadcast order; it draws attention to the order. The general call is used when passing out-of-routine orders or information of general interest.
The Officer of the Day call is used to attract the attention of the Officer of the Day to contact the gangway. The pipe is an order in itself and does not require verbal addition. The pipe consists of 4 high "pips".
a Commanding Officer of an HMC ship arrives onboard he/she is entitled
to this pipe. To be done properly it should be 12 seconds long with
very smooth transitions. To accomplish this, the sailor must take
a very long deep breath prior to beginning; failure to do so will
cause the pipe to be abruptly cut short. The side is also piped
for Royalty, teh Accused when entering a Court Martial and for the
Officer of the Guard (When the Guard is formed up).
The hands to dinner pipe is made at 1200 when the Ship's Company secures and commences the mid-day meal, referred to as dinner. It is never made for any other meal-time. The pipe is an order in itself and does not require any verbal addition. This pipe is very long and any is the pride of any sailor that can do it absolutely properly, and the disgrace of any sailor that does not.
The pipe down is made at 2230 or at any other time specified by the routine daily orders, when the Ship's Company retire for the evening and the silent hours period commences. The pipe is an order in itself and does not require any verbal addition. When this pipe is made during the middle of the day, it means that the ship is adopting a "Sunday Routine for the remainder of the day.
