BlockCoefficient

The block coefficient Cb is the moulded block coefficient corresponding to the waterline at the scantling draught Ts, based on rule length L and moulded breadth B:

$$C_b=\frac{Moulded displacement [m^3] at scantling draught T_s}{LBT_s} $$

Where:

• B : Greatest moulded breadth, in m, measured amidships at the scantling draught, Ts.

• Ts : Scantling draught, in m, at which the strength requirements for the scantlings of the ship are met

and represents the full load condition. The scantling draught is to be not less than that corresponding to the assigned free-board.(ref. IACS S2 Definition of Ship's Length L and of Block Coefficient Cb - S2.2 Block Coefficient $C_b$)
