Supercargo
A supercargo (from Spanish sobrecargo) is a person employed on board a vessel by the owner of cargo carried on the ship. The duties of a supercargo are defined by admiralty law and include managing the cargo owner's trade, selling the merchandise in ports to which the vessel is sailing, and buying and receiving goods to be carried on the return voyage.
