Type of warship
This article is about the type of warship. For the bus type, see Double-decker bus. For other uses, see Double decker.
A two-decker is a sail warship which carried her guns on two fully armed decks. Usually additional guns were carried on the upper works (forecastle and quarterdeck), but this was not a continuous battery and thus not counted as a full gun deck.
