The Maruader is a medium Frigate in service of the East India Trading Company. Appearing at level 23-25, this vessel carries five deck cannons and seven broadside cannons on each side. In addition to traditional ammunition, they attack with Firebrand rounds for the Broadsides and Chain Shot for the Deck Cannons. They are often found in the waters around Padres Del Fuego and the southern coast of Port Royal, as well as Isla Tormenta and Outcast Isle.
Game Note: Like most frigates, this vessel is weakest in the stern and has no aft facing guns. If you can get behind her and unload your broadsides there, that's where the armor is thinnest.
