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 ").

A pleasure boat with two lengthwise pontoons. A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called tubes) contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads.
In 1938 the Mk III version of the bridge was introduced with significant changes and an increase of load capacity to 9 tons, i.e. load class 9. [ 2 ] The Mk III version of the bridge was easy and quick to erect, which led in 1939 to its becoming the standard light bridging equipment, initially of the British armies, and the Allied armies during ...
A pontoon boat is a flattish boat that relies on nautical floats for buoyancy. Common boat designs are a catamaran with two pontoons, or a trimaran with three. [2] In many parts of the world, pontoon boats are used as small vehicle ferries to cross rivers and lakes. [3] An anchored raft-like platform used for diving, often referred to as a pontoon
A higher freeboard will give more room in the cabin, but will increase weight and drag, compromising speed. A higher freeboard, such as used on ocean liners, also helps weather waves and so reduce the likelihood of being washed over by full water waves. A low-freeboard vessel is susceptible to taking in water in rough seas.
Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage , was defined by the International Convention on Tonnage Measurement of Ships, 1969 , adopted by the International Maritime Organization (IMO) in 1969, and came ...
Tonnage is a measure of the capacity of a ship, and is commonly used to assess fees on commercial shipping.The term derives from the taxation paid on tuns or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship.
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).
