In the Age of Sail, arming or victualling a war ship or war vessel meant equipping the ship with all the necessary materials to navigate and the victuals necessary for the crew to subsist. In addition to the rigging (masts, sails and ropes), the victualler (or sutler) supplied water and provisions and, in some cases, cannons, offensive weapons and defensive weapons.
Victualling small boats without haste could be done in small facilities. On the contrary, the preparation of military fleets was usually carried out in large arsenals and shipyards.
In the Mediterranean there were many large centres where ships were built, armed and victualled, many of which were intended to support large military fleets. Examples include the Piraeus arsenal, the Carthage arsenal, the Tortosa shipyards, the Venice arsenal, the Barcelona shipyards, the Valencia shipyards, and the Mallorca shipyards.
In all cases, there were buildings, closed with a lock and key and with an armed guard, to store the necessary material, for example: pulleys, anchors, masts, yards, sails, auxiliary boats, rudders, oars, bombards, armor, pavises, crossbows, and pins. In the case of the Barcelona shipyards, there are many documents (inventories in particular) that list the variety of items needed to arm a ship.
