HydroComp PropExpert is a software tool for the sizing and analysis of propellers for workboats and pleasure craft. It provides the tools needed for the proper selection of propulsion system components - engine, gear and propeller. Development in 2010 has produced a number of new features for PropExpert, including: • Speed prediction – New speed prediction algorithms were developed to insure accurate prediction of real speed and power for Catamarans, Riverboats (new), and Sailboats. • Additional vessel types – In addition to the standard “Displacement”, “Planing” and other vessel types, new types (e.g., Riverboat) allow for improved prediction of associated Vessel parameters and speed prediction. • New data checking – Additional data checks confirm reliable performance, such as a new check for face cavitation with highly cupped propeller. Upcoming planned development efforts include: • A performance correction is in development for the effect of camber (progressive pitch). • PropExpert will be able to help correlate the analysis of a Prior trial to known values from an “overload test”, which will aid in describing accurate performance. HydroComp noted the sale of the 220th license of PropExpert late in 2010
