Meeting Your Thrust Demands

Accurate, Ideal Propulsors

Propulsors are the real money makers for marine vehicles. As the central element of the Vessel-Propulsor-Drive system model, propulsors provide the thrust that moves cargo, pushes ships around a harbor, or tows a fishing net. NavCad is the go-to software for selecting the ideal propulsor components for your vessel – whether propellers or waterjets. Maritime professionals requiring a greater understanding of their propeller’s performance utilize PropElements to conduct wake-adapted calculations for the optimized design of a contemporary propeller or for the critical evaluation of a particular propeller on the ship. For development of drawings and design documents, PropCad is the industry standard geometric modeler of propeller design-for-manufacture. Quickly assemble propeller designs from PropCad’s comprehensive library of popular styles and attributes from traditional to advanced – or build to your specific requirements.

Propeller Sizing for All Vessels

Propeller builders and sales staff require design tools that help define the right propeller for the system, from traditional styles to custom-designed for specific hydrodynamic objectives. Successful delivery of new propellers then demands properly sizing the selected propeller style of model for the application. NavCad assists propeller builders on in-depth systems analysis, while PropExpert sizes propellers for workboats and pleasure craft. Sales teams rely on HydroComp tools to deliver the correct propeller sizing solution for their customers.

Waterjet Matching Made Easy

NavCad predicts the steady-state performance of any waterjet-outfitted vessel. Plug this component into the system to judge waterjet performance on an existing vessel or for a new design. Performance prediction, waterjet matching, and forensic analysis of existing vessel performance all can include a waterjet as the propulsor. Use NavCad to aid sales and marketing teams in sizing and making solid product recommendations. 

Solutions for Complex Systems

Proper selection of the Propulsor for the Vessel and Drive is critical to successful operation of emerging and complex systems. At the cutting-edge of efficient and effective propulsion system design, maritime professionals rely on HydroComp’s NavCad and PropExpert programs for analyzing and selecting top-performing, profitable propellers and other propulsors.
