Note 1 — Chapter I · AMERICAN SHIPPING TO THE CLOSE OF THE WAR OF 1812

A frigate was a ship designed to be a fast, armed cruiser and mounted from twenty to fifty guns; when a naval vessel mounted less than twenty guns she became a sloop of war, and when she mounted more than fifty guns she became a line-of-battle ship. The frigate was always a favorite type of vessel with the officers and men of the navy, as she was faster and more easily handled than a line-of-battle ship, and was at the same time a more powerful fighting and cruising vessel than a sloop of war. Frigate-built means having the substantial construction, arrangement of the decks, masts, spars, rigging, and guns of a frigate.
