Surface-Piercing Propellers: Geometric Modeling with PropCad
Surface-piercing propellers (SPPs) have a very specific blade form, with cleaver shaped outlines, high pitch-to-diameter ratios, and carefully crafted wedge-shaped sections. As a result, successful surface-piercing propellers require the use of unique design elements....Propeller radiated noise: Meeting challenges for design and mitigation
The evaluation of Propeller Radiated Noise (PRN) has always been part of the assessment of internal noise, vibration, and habitability. In recent years, PRN has become a focal point for international regulatory efforts to reduce Underwater Radiated Noise (URN). While...

We all know that waterjets are a very effective propulsor for high speed craft. But how do we model waterjet performance for speed-power calculations? What is the influence of hull form on their ability to drive a craft? How are waterjets different from propellers for...Pushboats and Propellers
Pushboats are the industrial workers of commerce, moving barges from place-to-place on rivers across the globe. And we appreciate their tireless transport of goods and cargo now more than ever. But what makes a pushboat different from a merchant ship or motor yacht?...Designer-guided hull form optimization
Vessel hull form drag is the principal system load that ultimately determines engine power, fuel consumption, and emissions, and we know that reducing this hydrodynamic “cost” is an important design objective. But is there a “best” hydrodynamic shape to achieve least...
