D&D 3.0: Tales from Mystara
Fitted with a towering forecastle and sterncastle, this huge, broad-beamed sailing ship is almost a seagoing castle. It has four masts and is not remotely nimble, but it is large and sturdy and can carry hundreds of sailors and soldiers. It has multiple decks, and the mainmast often has one or more fighting tops, small platforms suitable for archers to fire down at other ships.
Greatships are sometimes called carracks.
