What type of watch is most commonly stood by Sailors?

The most commonly stood type of watch by Sailors is the deck watch. Deck watches are essential for maintaining the overall safety and security of the vessel while navigating. This type of watch involves a variety of duties, such as monitoring the environment, communicating with other crew members, and ensuring that operational protocols are followed. The responsibilities of those on watch directly contribute to the proper functioning of the ship and the safety of all aboard.

On the other hand, security watches, engineering watches, and alert watches serve specific purposes but are not typically as universally required across all types of vessels as deck watches. Security watches focus on the protection of the ship and its personnel, engineering watches concentrate on monitoring the machinery and systems, and alert watches are designed for emergency situations. Each of these has its importance but does not match the commonality of the deck watch in the routine operations on Navy ships.
