This is an excel sheet which calculates the total Calm Water Resistance of a Ship. It calculates all the components as per the Holtrop and Mennen method (1978) to give final calm water resistance. It can also generate a Speed-Resistance curve for different speeds entered by user.
Very useful in Powering calculations.
Generates Speed-Power curve
Calculates all the different components, viz., Frictional Resistance, Wave Resistance, Additional Resistance due to Bulbous Bow/Transom Stern, Correlation Resistance, Appendage Resistance
Simple and easy to use
A video demo on youtube is here (please note the video is on version 0 which didn't have the option of generating Speed-Power curve; the Rev 1 generates Speed-Power curve as well):
