BEAM
The width of a ship. Also called breadth.

BREADTH
The width of a ship.

MOLDED BEAM
The maximum breadth of a hull measured between the inboard surfaces of the side shell plating of flushplated ships

LIB
Length Breadth Ratio

CB
Block coefficient  a measure of the fullness of the form of the ship and is the ratio of the volume of displacement to a given waterline, and the volume of the circumscribing solid of constant rectangular crosssection having the same length, breadth and draught as the ship. CB= (L x B x T) The LPP is normally used in calculating the value of CB which varies with the type of ship. Fast ships Ordinary ships Slow ships 0.500.65 (fine form) 0.650.75 (moderate form) 0.750.85 (full form)

B
Breadth moulded  the maximum beam, or breadth, of the ship measured inside the inner shell strakes of plating, and usually occurs amidships.

BREADTH EXTREME
The maximum breadth including all side plating, straps, etc.

BE
Breadth extreme  the maximum breadth including all side plating, straps, etc.

MIDSHIP SECTION AREA COEFFICIENT
(CM): The ratio of the immersed area of the midship section to the area of the circumscribing rectangle having a breadth equal to the breadth of the ship and a depth equal to the draught. CM = AM (B x T), CM values range from about 0.85 for fast ships to 0.99 for slow ships.

MOULDED BREADTH
The internal extreme breadth of a vessel amidships, from inside the plank, plate of ceiling.
