HydroComp Offers New Ship Propulsion Design Software

Since 1984, marine professionals worldwide have chosen NavCad software as one of their principal design tools for the analysis and selection of engine, gear and propeller systems. HydroComp, Inc., Durham, N.H., has produced NavCad 2.0—the most powerful NavCad software to date.

The PC.-based NavCad system has been built around three main calculation routines: (1) vessel resistance; (2) propulsive coefficients and shaft power; and (3) propeller selection and analysis. Analysis methods are available for displacement vessels, planing craft, and barge trains. A comprehensive propeller analysis and an optimum propeller selection can be performed for a variety of open-wheel and ducted propellers.

NavCad 2.0 also represents a new look and direction for NavCad software.

An integrated, menu-driven data entry system provides the control for the calculations—with data checking, context-sensitive help screens, and logical file handling.

Also, NavCad 2.0 adds comparative analyses, graphing capabilities and report generating to its other features.

The flexibility and power of Nav- Cad 2.0 are evident the moment one enters the first screen. Even a new user will find that they can instantly perform all of NavCad's functions through the pull-down menu system and data entry screens.

NavCad 2.0 requires an IBM PC or compatible computer operating MS-DOS 3.0 or greater, with 640K RAM, and a hard disk drive. A numeric coprocessor, and EGA or VGA video are recommended. NavCad supports 5-1/4- and 3-1/2-inch formats.
