Bouvier's Law Dictionary, Revised 6th Ed (1856)
DEMURRAGE, mar. law. The freighter of a ship is bound not to detain it,
beyond the stipulated or usual time, to load, or to deliver the cargo, or to
sail. The extra days beyond the lay days (being the days allowed to load and
unload the cargo), are called the days of demurrage; and that term is
likewise applied to the payment for such delay, and it may become due,
either by the ship's detention, for the purpose of loading or unloading the
cargo, either before, or during, or after the voyage, or in waiting for
convoy. 3 Kent, Com. 159; 2 Marsh, 721; Abbott on Ship. 192 5 Com. Dig. 94,
