Calculate hull wetted surface area (wettedSA) (m^2) using the Holtrop & Mennen method.

calcHMWettedSA(lwl, actualDraft, breadth, Cm, Cbw, Cwp, Abt)

Arguments

lwl

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

actualDraft

Actual draft (vector of numericals, m)

breadth

Moulded breadth (vector of numericals, m)

Cm

Midship section coefficient (vector of numericals, dimensionless) (see calcCm)

Cbw

Waterline block coefficient (vector of numericals, dimensionless) (see calcCbw)

Cwp

Water plane area coefficient (vector of numericals, see calcCwp)

Abt

Traverse bulb area (vector of numericals, m^2) (see calcAbt)

Value

wettedSA (vector of numericals, m^2)

Details

Actual draft is typically obtained from sources such as AIS messages or ship records.
