A gangway is a movable bridge, ramp, or platform used as a secure passageway between a ship and the shore or another vessel, enabling safe boarding and disembarking. It serves as the primary entrance/exit, often featuring handrails, and is crucial for moving passengers, crew, and cargo.

Key Details About Gangways:
Structure: Often a metal walkway or bridge (sometimes called a gangplank or accommodation ladder) that adjusts to changing tides and ship heights.

Location: Typically found at a designated opening in the railing or side of a ship.

Usage: Used during docking for passengers and crew to walk on or off the vessel.

"Gangway Up": This nautical term indicates that the gangway has been officially removed or lifted, signaling that passengers are no longer able to board or disembark, often denoting the ship's imminent departure.
