The work surveys naval life during the age of sail, opening with ship design, construction, materials, sheathing and rigging, then explaining armament and gun operation. It sketches the ship's internal layout deck by deck and profiles officers, warrant officials and ordinary seamen, describing duties, hierarchy, messes, clothing and provisions. Later chapters cover discipline and punishments, conduct in battle and daily routines at sea and in port, alongside crew songs, signals and customs. Illustrated technical notes and an appendix complement vivid accounts of shipboard work, sailing maneuvers, and the social atmosphere of life aboard men-of-war.
