What is the main purpose of the gangway watch?

The main purpose of the gangway watch is to maintain continuous watch for security and safety. This role is crucial for ensuring that only authorized personnel are allowed access to the ship, which helps to protect against potential threats and maintain a secure environment on board. The gangway watch serves as the first line of defense by monitoring who enters and exits the vessel, checking identification, and ensuring that safety protocols are observed.

By being vigilant and aware of their surroundings, the gangway watch helps to prevent unauthorized access, which could lead to security breaches or safety incidents. Their presence also reassures crew members and visitors about the safety measures in place on the ship. Therefore, the primary focus of the gangway watch aligns directly with the overarching need for security and safety on board a ship.
