 Safe rooms sometimes have facilities to allow the crew to remotely disable the ship's engines and electronic systems, making it impossible for the pirates to sail the ship to a location they control.The safe room is also typically armoured against direct physical attack, to allow the crew to remain safe for a few hours, even if located by the pirates, and to allow rescuing forces full scope for the use of armed force to re-take the ship without risk to the crew.The effect of the safe room is thus to deny the pirates access to the crew for hostage-taking, to remove the capability to move the ship to a location favourable for the pirates, and to facilitate retaking the ship by armed force without risk to the crew.
