Ship-of-the-line captain (French: capitaine de vaisseau; German: linienschiffskapitän; Italian: capitano di vascello; Spanish: capitán de navío; Serbo-Croatian: kapetan bojnog broda) is a rank that appears in several navies. The name of the rank derives from the fact the rank corresponded to command of a warship of the largest class, the ship-of-the-Line, as opposed to smaller types (corvettes and frigates). It is normally above the rank of frigate captain.
