SHIP: The navigation room is where vital devices are located: the GPS system which accurately identifies the coordinates of the ship, the acoustic depth finder which measures depth, the speed log observing speed and the gyro compass which indicates direction. This is where the technologies allowing the ship navigate safely anywhere in the world meet.

COMMANDER OF THE SHIP: The radio room is the place where communication between ships and coast radio stations is established. This is where messages are transmitted orally or in writing, securely and confidentially. Access to this area is restricted to those with a security clearance and is approved by the ship’s commander.
