HydroComp Inc., of Durham, NH USA, is pleased to announce the release of NavCad™ 3.7. NavCad is a naval architect's tool offering an integrated platform to predict resistance and power, and to determine optimum propeller parameters. The two most valuable additions to this initial release of version 3.7 include: new prediction methods and optimum trim analysis.

A number of new resistance prediction methods have been added for semi-displacement hulls. These include VTT Round Bilge, VTT Hard Chine, the U.S. Navy CRTS method and Jin-1988. (More new methods are under development, and some of the existing semi-displacement prediction methods have been improved through our usual on-going validation process.) A shallow water added drag method for fast monohulls has also been developed.

Optimum trim analysis (similar in operation to NavCad's Minimum Drag Analysis) allows a user to identify the vessel trim which has the minimum drag. User entry of LCF and GML insure the proper calculation of the LCG shift and transom immersion.

On-going developments for the coming months will strengthen the use of NavCad™ for ship design and operation. Upcoming features will include a conceptual bulb designer to help identify basic geometric parameters of a bulbous bow during the early design stages, and a voyage analysis spreadsheet to help plan route options and review designs over an entire operating profile.

HydroComp, Inc. provides software products and consultancy services for the performance analysis and design of marine vehicles to industry, research and government clients. Currently over 330 marine professionals in 34 countries worldwide are using HydroComp software.
