What is the purpose of a "gangway" on a naval vessel?

The purpose of a "gangway" on a naval vessel is to provide an opening in a bulwark or lifeline that allows access to a brow or accommodation ladder. This feature is essential for the safe and efficient boarding and disembarking of personnel and visitors to and from the ship. It facilitates movement between the vessel and the pier or other ships, ensuring that crew members can enter and exit safely while maintaining proper ship security. The gangway's design typically includes safety measures to prevent accidents during these transitions. Understanding its role is crucial for ship operations and ensuring the safety of personnel during embarkation and disembarkation activities.
