Weight distribution and the carronade trade-off

Gun weight, hull form, stores, ballast, and metacentric height constrained where a battery could be installed. Heavier long guns normally belonged lower in a large ship because putting them high increased dangerous topweight. The carronade reduced both weapon weight and crew requirements, making it useful on merchant vessels and the upper works of warships. Its low charge and short range, however, prevented it from replacing long guns in a distant engagement; outside its effective range it produced little more than smoke. Designers therefore had to calculate the complete distribution of hull, stores, ballast, and broadside forces rather than apply a standard battery by rate alone. The Mary Rose illustrates how sixteenth-century losses fed continuing debate over stability, open gun ports, and weapon selection. These questions were already under discussion when she sank, while early designers still lacked the later range of proven armament choices.
