What is manning the rail?

Manning the rail is a naval tradition where sailors line up on the deck of a ship during special occasions, such as when entering or leaving port or when passing by another ship. The sailors stand at attention and face outward, holding onto the ship's railing or gunwale, and often salute or wave to those on shore or aboard other vessels. This tradition is meant to show respect and honor for the occasion or individuals being recognized, and to demonstrate the unity and pride of the ship's crew. Manning the rail can also be used as a form of tribute or farewell to fallen comrades, with sailors standing in silence to pay their respects as the ship conducts a burial-at-sea ceremony.
