Traditions

A basic tradition is that all ships commissioned in a navy are referred to as ships rather than vessels, with the exception of destroyers and submarines, which are known as boats. The prefix on a ship's name indicates that it is a commissioned ship.

An important tradition on board naval vessels of some nations has been the ship's bell. This was historically used to mark the passage of time, as warning devices in heavy fog, and for alarms and ceremonies.

The ship's captain, and more senior officers are "piped" aboard the ship using a Boatswain's call.

In the United States, the First Navy Jack is a flag that has the words, "Don't Tread on Me" on the flag.

By English tradition, ships have been referred to as a "she". However, it was long considered bad luck to permit women to sail on board naval vessels. To do so would invite a terrible storm that would wreck the ship. The only women that were welcomed on board were figureheads mounted on the prow of the ship.

Firing a cannon salute partially disarms the ship, so firing a cannon for no combat reason showed respect and trust. As the tradition evolved, the number of cannon fired became an indication of the rank of the official being saluted.
