What is NavCad?
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. NavCad is based on a “document-centered” architecture, correctly known as a Multiple Document Interface. In other words, the main NavCad window contains and processes graphs, as well as controls the operation of the data entry and calculations. Most Windows business applications (e.g., word-processors, spreadsheets) are arranged in much the same way. At the top of the window is the Main Menu (File, Edit, etc.) containing the many menu commands which bring up data entry forms and launch calculations. Immediately underneath is the Toolbar with buttons for frequently-used commands. To the left of the screen are the Resistance Build View and Propulsion Build View. To the center/right is the Graph Window. On top of the graph is the Performance Summary spreadsheet.
