PropExpert Software: Propeller Analysis & Sizing Software
PropExpert is HydroComp’s software for propeller sizing and marine propulsion system analysis, helping engineers select the optimum propeller, engine and gearbox for a wide range of vessels. Using fast and accurate calculation methods, it enables users to evaluate different propulsion configurations and predict vessel performance before installation. As the official HydroComp distributor, VICUSdt provides expert support for implementing PropExpert alongside NavCad as part of a complete propulsion design workflow.
What Is PropExpert Software?
Designed for fast and reliable propulsion system sizing, PropExpert is HydroComp’s software for analysing and selecting propeller systems for recreational boats and workboats. With only a few key vessel parameters, it enables engineers and designers to evaluate different propulsion configurations before making design decisions or replacing existing components.
The software helps identify the optimum combination of propeller, engine and gearbox by predicting vessel performance using proven calculation methods. Whether supporting a new design, a repowering project or a propulsion upgrade, PropExpert provides rapid and accurate analysis to compare alternatives, estimate performance and select the most suitable propulsion system for each application
Extensive Propeller Library
PropExpert includes an extensive library of commercial propellers that can be expanded with custom propeller models to suit specific applications or manufacturer data. This flexible approach allows users to compare different propeller options quickly while maintaining consistent engineering criteria throughout the design process.
The software also supports dedicated libraries for vessels, engines and gearboxes, making it easy to store and reuse project data across future analyses. By managing all propulsion system components within a single environment, engineers can accelerate the design process, reduce repetitive data entry and improve consistency across multiple projects
Key Features of HydroComp ProExpert
HydroComp PropExpert combines propeller sizing, propulsion system analysis and vessel performance prediction within a single engineering environment. By bringing together the key tools required to evaluate propellers, engines and gearboxes, the software enables users to compare different configurations, optimise system performance and identify the most efficient propulsion solution for each vessel.

Supports a Wide Range of Marine Propellers
PropExpert determines the optimal diameter, pitch, blade area and RPM for commercial inboard propellers with two to five blades, supporting diameters from approximately 450 mm (18 inches) to 2.5 m (100 inches). The software is compatible with a wide range of propeller designs, including flat-faced (Gawn), foil-section (B-Series) and ducted (Kaplan) propellers, making it suitable for a variety of commercial marine applications.
It also evaluates cupped and progressive pitch (cambered) propellers, accounting for their specific performance characteristics, and provides dedicated support for folding and stern pocket propellers. This broad compatibility enables naval architects and marine engineers to accurately size and assess propellers across different vessel types, operating conditions and propulsion requirements.
Applications and Industries Using PropExpert
PropExpert is used by naval architects, marine engineers, boat builders and propulsion specialists who need to size, analyse and validate propulsion systems with confidence. Its advanced calculation capabilities support accurate propeller selection and performance evaluation throughout the design and optimisation process.
The software is suitable for a wide range of vessel types and marine applications, making it a valuable solution for professionals working in commercial, workboat, passenger, fishing, defence and other specialised sectors where propulsion efficiency and reliability are essential
