NavCAD v2021 - Reliable and Confident Performance Prediction

Hydrodynamic and Propulsion System Simulation

Quickly analyze vessel speed and power performance. NavCad provides maritime designers with the necessary tools for the optimized selection of suitable propulsion system components.

Unsurpassed in hydrodynamic design and analysis of ships

NavCad is the premier hydrodynamic and propulsion system simulation tool, providing powerful systems engineering calculations for the performance of marine vehicles. NavCad is built on a physics-based performance equilibrium of the Vessel-Propulsor-Drive system model, and is known for its reliable and confident prediction.

NavCad contains an extensive library of prediction methods for hulls, propulsors, and all necessary pieces, making it the most efficient and comprehensive platform for analysis from early-stage design through post-delivery trial evaluation. Used for any type of monohull or catamaran vehicle from large displacement vessels to fast planing craft to submersibles, it supports a variety of multiple drive options, including IC engines and electric motors.

Whether the focus is vessel, propulsor, drive – or the system – NavCad remains the gold-standard of performance prediction for more than 30 years.

Advanced Analyses

The advanced features in NavCad allow you to go beyond speed prediction. Quickly analyze a project for bollard towpull or determine time-to-speed using an acceleration analysis. Use a variety of multiple drive options, including IC engines and electric motors. Employ existing assets such as model tests, sea trials, or CFD calculations to correlate and align predictions – bringing you the highest fidelity with the least cost. Use supplemental analyses to check hydroacoustics, sinkage and trim, drag reduction, dynamic planing stability, and more.
