Calculates the maximum block coefficient (Cb) (dimensionless) based on a ship's maximum displacement and and maximum draft.

calcCb(maxDisplacement, lwl, breadth, maxDraft)

Arguments

maxDisplacement

Maximum ship displacement (vector of numericals, m^3)

lwl

Waterline length (vector of numericals, m) (see calclwl)

breadth

Moulded breadth (vector of numericals, m)

maxDraft

Maximum summer load line draft (vector of numericals, m)

Value

Cb (vector of numericals, dimensionless)

Details

The block coefficient is the ratio of the vessel's displacement and its volume, defined by its waterline length (lwl), breadth, and draft: $$Cb=\frac{displacement}{lwl*breadth*draft}$$

This function returns the maximum block coefficient (Cb), which is the ratio of the vessel's maximum displacement and it's maximum volume, defined by its waterline length (lwl), breadth, and maximum draft: $$Cb=\frac{maxDisplacement}{lwl*breadth*maxDraft}$$
