Full load displacement and loaded displacement have almost identical definitions. Full load is defined as the displacement of a vessel when floating at its greatest allowable draft as approved by the load line assigning authority which is either the flag state (USCG etc) or a classification society (and designated by its " load line ").

Shipping costs have historically been calculated on the basis of gross weight in kilograms or pounds.By charging only by weight, lightweight, low density packages become unprofitable for freight carriers due to the amount of space they take up in the truck/aircraft/ship in proportion to their actual weight.
Planners can also load a 40 feet container on top of two units of 20 feet container, this known as a "Russian stowage" or "mixed stowage". [21] Hatch cover clearance – Hatch cover clearance refers to how many "High Cube" (height over 8.6 ft (2.6 m)) containers allowed to load in the hold without preventing the hatch cover from closing correctly.
Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage).
Less-than-truckload shipping or less than load (LTL) is the transportation of an amount of freight sized between individual parcels and full truckloads. [1] Parcel carriers handle small packages and freight that can be broken down into units less than approximately 150 pounds (68 kg). Full truckload carriers move entire semi-trailers. Semi ...
Invented in the early 20th century, 40-foot intermodal containers proliferated during the 1960s and 1970s under the containerization innovations of the American shipping company SeaLand. Like cardboard boxes and pallets , these containers are a means to bundle cargo and goods into larger, unitized loads that can be easily handled, moved, and ...
The first load line regulations for shipping were domestic in nature, primarily as a result of improvements by Samuel Plimsoll, the British Board of Trade and associated UK Merchant Shipping in the 1870s. [2] These eventually led to the first International Convention on Load Lines in 1930.
Full load departure or full displacement [ edit ] Along with all the Lightship loads, the vessel has all systems charged meaning that all fresh water, cooling, lubricating, hydraulic and fuel service header tanks, piping and equipment systems are filled with their normal operating fluids.
