Sideboy
A sideboy is a member of an even-numbered group of seamen posted in two rows at the quarterdeck when a visiting dignitary boards or leaves the ship, historically to help (or even hoist) him aboard, in a ceremony known as tending the Side. Presently, Sideboys are used only for ceremonial purposes and not always aboard ships. For example, they may be used for Change of Command and Retirement ceremonies. Sideboys are instructed by the piping of the Boatswain's Mate. Despite the seemingly sex-specific name of this function, in reality the sideboy function may be performed by either male or female members of the ship's complement.
