The draft (American) or draught (British) of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel), with the thickness of the hull included; in the case of not being included the draft outline would be obtained. [1]

Angle of list

The angle of list is the degree to which a vessel heels (leans, or tilts) to either port or starboard.

Archimedes' principle

Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces.

Beam (nautical)

The beam of a ship is its width at the widest point as measured at the ship's nominal waterline.

Bow (ship)

The bow is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway.

The word cargo refers in particular to goods or produce being conveyed – generally for commercial gain – by ship, boat, or aircraft, although the term is now often extended to cover all types of freight, including that carried by train, van, truck, or intermodal container.

Center of mass

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero or the point where if a force is applied causes it to move in direction of force without rotation.

Keel depth

Keel depth (sometimes given as Depth to keel) is the depth (or draft) of water from the water surface to the keel of a submarine, its deepest part.

Length between perpendiculars

Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the waterline from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.

Length overall

Length overall, often abbreviated as (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline.

Squat effect

The squat effect is the hydrodynamic phenomenon by which a vessel moving quickly through shallow water creates an area of lowered pressure that causes the ship to be closer to the seabed than would otherwise be expected.
