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....

Waterjets in NavCad

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...

Article: Propeller Considerations for Inland-River Pushboats

Inland river pushboats operate in a harsh environment. Transiting our rivers, bays, lakes, and inland waterways, these vessels push barges between hubs of commerce. Swift currents, trash and debris, heavy traffic, and narrow waterways are day-to-day realities for...
