Merchant gunports were often real rather than painted decoration. Armed traders could mount carronades or other weapons to discourage pirates and privateers. Their decisive weakness was manpower: a merchant crew was much smaller than the complement of a Royal Navy warship, while French and Spanish warships often carried still more men. Appearance could therefore exaggerate a merchantman's sustained gunnery, sail-handling, and boarding capacity even when the hull genuinely carried weapons.

Merchant gunports could conceal a manpower weakness
Real gunports and carronades could make a merchantman look formidable, but its smaller crew sharply limited how much of that apparent fighting power it could use.
