Hullspeed simply calculates the resistance of the hull. In case you wish to determine how much power in [kW] is needed to overcome that resistance the following formula applies: Power [kW] = Resistance [kN] * speed [m/s] * overall efficiency [% / 100] By selecting [Data | Efficiency ] you can specify the overall efficiency of your propulsion arrangement. By default Hullspeed uses a 100% efficiency. By selecting [Data | Graph type ] you can select which unit you want Hullspeed to show in the graph versus speed.
