Join us for this 30-minute webinar that will introduce differences between ICE and EM power curves, as well as discuss the implications of EM power curve shapes for different operating modes (such as transit or towing), continuous versus peak conditions,... Read more
Join us for this 30-minute webinar which will introduce how DC motors impact vessel performance and propeller selection, with comparisons to internal combustion engines. We will discuss the implications of DC motor power curve shapes for different operating modes... Read more
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 the system – resistance, propeller performance, hull-propulsor... Read more
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 catamaran forms affect planing predictions? What is the influence of... Read more
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 together? Can we use analytical tools to optimize a design? This... Read more
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 compromise performance – frequently causing an overload of the engine and a... Read more
