Koefisien Bentuk Kapal

2. Coefficients Water Line (CWL)
AWL = Water Line Area
LWL = Length Water Line
B = Breadth
CWL = AWL / LWL
LWL B

3. Coefficients Midship(Cm)
Am = Midship Area
B = Breadth
T = Depth
Cm = Am / B.T T B

4. Coefficients Block (Cb)
Cb = V / (LWL . B . T)
V = Volume of Carene
LWL = Length Water Line
B = Breadth
T = Depth
LWL T B

5. Prismatic Coefficients (Cp)
There are 2 Prismatic Coefficients :
Longitudinal Prismatic Coefficients (CPL) = V / (Am . LWL)
Tranversal Prismatic Coefficients (CPT) = V / (AWL . T)
V = Volume of Carene
Am = Midship Area
AWL = Water Line Area
LWL = Length Water Line
