Dead Man's Trough is a cursed area in the Caribbean Sea. It gets its name from the vicinity of Davy Jones' Crew - Isla Tormenta, which is found here. The Trough is found between Isla Tormenta and Cuba.
Several Light patrol ships of the Royal Navy and the EITC are found here, which do not pose much of a threat to highly skilled pirates. The ones to be feared are the patrolling Warships of the Navy, or the ones of the Undead that roam around, waiting to plunge upon their prey.
