The ship scale appended resistance coefficient is calculated by adding the ship scale
appendage resistance coefficient,
, to the bare hull values obtained from the equation in Propulsion Factors Estimation. The
values displayed in the output are the appended resistance coefficient,
.

The ship scale appendage resistance coefficient,
, is calculated according to Holtrop & Mennen, References 1 and 2 for which you have to specify individual wetted surface areas and appendage
resistance factors
for each appendage.
