Hydrodynamics of Propeller Accidents Part 2 – Right Whale Collision Research

Following up on Hydrodynamics of Propeller Accidents Part 1, we now share some research work that looks very applicable to future hydrodynamic studies of human body / swimmer / man overboard interactions with boats, drives, propellers, and propeller guards. We recently came across some hydrodynamic studies of whale interactions with ships, ship hulls, and ship […]

Hydrodynamics of Propeller Accidents – Part 1 the History

Little research has been done surrounding the hydromechanics of people / swimmers/ man overboard encounters with propellers or propeller guards. We will now explore this field, some of the opportunities it presents, and some recent research that looks very applicable to studying the hydrodynamics of human / boat / propeller / propeller guard interactions. We […]

Computational Fluid Dynamics (CFD) in Modeling & Testing of Propeller Guards

We have been promoting the use of Computational Fluid Dynamics (CFD) in the development of prop guards for a long time. It’s been on our Help Us page for several years, we mentioned CFD in our January 2009 post on a Propeller Guard With Reduced Drag, and just a few days ago we briefly discussed […]

Propeller Guard Paradox Defense Defeated by Uncle Milton’s Ant Farm

From the mid 1990’s up to December 2002, the boating industry relied upon Federal Preemption as their primary defense in propeller accident cases. The industry said that since the U.S. Coast Guard did not require propeller guards on all boats, then individual states could not require them to have been on the boat involved in […]
