New features for the industry-standard resistance and propulsion software. HydroComp NavCad is a software tool for the prediction and analysis of vessel speed and power performance. It also provides for the selection of suitable propulsion system components – engines, gears and propellers. HydroComp has been working since late 2009 on the development of a new architecture for NavCad, and improvements to the interface. This new platform was developed with an eye to the future, and will provide a new structure for future development.
