LIGHTER General name for a broad, flat-bottomed boat used in transporting cargo between a vessel and the shore. The distinction between a lighter and a barge is more in the manner of use than in equipment. The term "lighter" refers to a short haul, generally in connection with loading and unloading operations of vessels in harbor while the term "barge" is more often used when the cargo is being carried to its destination over a long distance.
LIGHTER ABOARD SHIP An ocean ship which carries barges. these Barges are loaded with cargo, often at a variety of locations, towed to the ocean ship, Sometimes referred to as the mother ship, and lifted or, in some cases, floated on board. after the ocean crossing, the Barges are off-loaded and towed to their Various destinations. the ocean ship then receives a further set of Barges which have been assembled in readiness. this concept was designed to eliminate the need for specialized port equipment and to avoid transshipment with its consequent extra cost.
