NavCad

NavCad is a comprehensive software application specifically designed to help you predict the power performance of naval ships by filling out some information. It allows you to calculate the resistance, analyze the vessel and propulsion, and more.

Neatly organized interface

After a brief and uneventful setup procedure, you are welcomed by a normal window with a well-structured layout. It may seem overwhelming at the first glance, especially when showing the editors for the condition, hull, appendages, environment, margin and propulsor.

Customize parameters, create tasks, generate graphs

You can edit their properties, toggle between resistance and propulsion viewing mode, add new tasks for standard speed prediction, quick propeller sizing, sea trial analysis and model test entry, as well as view a graph with the speed. Tasks may also be created with custom data.

Resort to handy tools

It is possible to evaluate the vessel by generating quick reports for dynamic stability and trim, drag reduction along with effect of initial trim, perform a propulsion analysis when it comes to a blade scan, hydroacoustic and vessel benchmarking, predict submarine/SWATH data, as well as export the propeller CAD shape together with the graph.

Evaluation and conclusion

There were no stability issues in our testing, since NavCad did not hang, crash or pop up error messages. It leaves a small footprint on system resources, using low CPU and RAM. Unfortunately, a lot of the app's important features are not available in the unregistered version of the product, so they cannot be tested without making a purchase.
Taking everything into account, NavCad proves to be a resourceful piece of software for analyzing and predicting various aspects of naval vessels.
