NavCad Premium is primarily focused on advanced optimization capabilities and features tailored to larger vessels. Key benefits include access to a built-in scripting language and the ability to run NavCad as a silent calculation server for design space exploration. This allows seamless coupling with commonly used tools such as Excel and MATLAB, as well as optimization platforms like CAESES.

Additional benefits for larger ship applications include support for dual-fuel engines, EEXI assessment and CO₂ emissions analysis, operating mode (duty profile) evaluation, and an advanced ship resistance method that bridges the gap between traditional parametric approaches and full CFD analysis.
