GURPS Vehicles: War Galleys
This historical gaming supplement covers oared warships from early Greek biremes and triremes through the powerful galleys of the 16th century. It includes vehicle statistics for more than 30 vessels, naval tactics, expanded ramming rules, and hit locations for large oared ships. Information on crew life from two eras is accompanied by game statistics for crew members and ready-to-use NPCs. Deck plans for a trireme and a great galley are provided in labeled and handout formats, along with adaptation advice, a worldwide overview of war galleys, a development timeline, and a bibliography.
