Why seventeenth-century ship labels mislead

Spanish treasure ships carried cargo by sacrificing heavy gun space, while Stayner's English ships mounted much stronger batteries. Contemporary terminology remained unstable: frigate-built vessels could serve with fifty to more than sixty guns and later be rated as ships of the line. Fleet standardization had not reached the clearer eighteenth-century system, and contemporary gun totals could vary between records. Four Speaker-class vessels fought at Cadiz and showed the design's usefulness even while contemporaries disagreed over its category. Hull design and procurement choices shape deterrence, peacetime conflict management, and wartime options even when the labels are imprecise. Speaker, later renamed Mary, and her sisters show why hull form, armament, and operational role matter more than a single period label.
