A coefficient used in the preliminary estimations of the power required in a new design to attain the desired speed.
Floating, not controlled, without a clearly determinable direction. A vessel is said to be adrift when she breaks away from her moorings.
A solid substance used to remove components from a gas being processed.
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface.
The distance that the ship has advanced in a direction parallel to the original course measured from the point where the helm was put over. See also Manoeuvring parameters.
In the field of physics, engineering, and earth sciences, advection is the transport of a substance or quantity by bulk motion of a fluid.
The aerodynamic force which acts parallel to the direction of wind flow.
The aerodynamic force which acts perpendicular to the direction of wind flow.
Aerodynamics is the study of motion of air, particularly when affected by a solid object, such as a wind turbine blade.
In a floating condition; the opposite of aground.
A tanker with deadweight of 79,999dwt, however the term Aframax is generally used for tankers in the 50,000 – 100,000dwt capacity range.
A type of lifting gear often installed on stern of cable vessels, pipe-lying vessels and offshore construction vessels for sub sea load handling.

The part of the ship form where the parallel middle body and the run meet.

Agrivoltaics is co-developing the same area of land for both solar photovoltaic power as well as for agriculture. The coexistence of solar panels and crops implies a sharing of light between these two types of production.
When a vessel rests on something solid other than the blocks in a dry-dock or slipway she is said to be aground.
