Prediction Confidence: NavCad Features to Reduce Calculation Uncertainty

As we analyze or design a vessel, we use NavCad for hydrodynamic and propulsion system simulation. The Vessel-Propulsor-Drive system model is built upon predictions for the various component pieces of …

3D Propeller CAD: Intro to Concepts, Tools, and Formats

3D CAD models are the standard for communicating propeller design data. These are used in various forms for visualization, performance simulation, and manufacturing/machining operations. In this half- …

Ducted propellers: Nozzle selection and hydrodynamics

Nozzles can be an incredibly valuable partner for a propeller. When used appropriately, these non-moving devices can supplement a propeller’s thrust for some applications – but not all. How can a non- …

Planing Craft in NavCad: Data, Settings, and Options

We all know about planing hull drag prediction and typical hull form parameters – such as deadrise, LCG, chine beam. But what about the longitudinal and transverse variation in deadrise? Or how catama …

Rudder Design: Practical and Analytical

We all know that rudders are a vital piece of our vessel’s operational equipment. But what determines the best type of rudder to use? How do we ensure that the rudder and propeller function well toget …

Engine curves: Implications for Propeller Sizing and Vessel Performance

Rated power and RPM will put an engine into a general category, but it does not tell the whole story about an engine’s power delivery. How do differences in engine power curve affect towing capability …

After-market Modification of Propellers to Achieve Performance Objectives

Propeller hydrodynamics can be complicated and messy, and sometimes the combination of propeller, vessel shape, gearbox, and engine are less than perfect. Age or lack of maintenance can also compromis …

Hull-Propeller Interaction – Part 1: Wake Fields

This two part series on Hull-Propeller Interaction complements our previous webinar on propeller-radiated noise with a focus on Wake Fields (Part 1) and Propeller Performance (Part 2). We discuss in …

Certificate courses and workshops

Our new HYDROCourses were designed to provide clear and consistent content and to facilitate easy-to understand delivery of typically complex topics. These courses will sharpen your existing proficiencies – or even build new skills – while providing practical and insightful knowledge. Explore key subjects about hydrodynamics and propellers in a flexible on-demand format, so learning is at your own pace and convenience.


Newly Added Courses

Propeller Repitching

This certificate course is appropriate for propeller repair shops, propulsion equipment vendors, naval architects, and boat builders seeking repitch knowledge.

Pushboats and Propellers

This certificate course will review important characteristics of pushboats propellers and is vital for those involved with inland waterways transport systems.

Engine Power Curves

This certificate course will review how a full engine power curve is needed to properly evaluate vessel performance in off-design and dynamic conditions.
