Light cargo. Goods which fill the ship's cargo space cubically but do not bring it "down to its marks", are called "light cargo", in contrast with heavy cargo, which brings the ship down to its marks but does not completely fill the space available for cargo.
Longshoremen. These are workers in a port and who are involved in the handling of cargo. In most places they are called "stevedores" but particularly in the U.S.A. the name given to these workers is "longshoremen".
LIFO (Liner In Free Out). This abbreviation indicates that the shipowner bears all casts for loading; stowing and trimming the cargo and all the costs incurred for the discharge are to be borne by the charterer, or receiver, or consignee.
