While both events share some potentially horrible outcomes and spark fear in victims and onlookers, propeller accidents are actually much more frequent. This post is being written in response to […]

Stephen Keller Boat Propeller Accident – Boat Propeller Fatality Statistics Under Reported – San Jose Mercury News Misinforms Readers

Stephen Keller’s fatal boat propeller accident on Lake Tahoe Saturday August 27, 2011 was covered by San Jose California’s Mercury News, because Stephen Joseph Keller DDS was a dentist in San Jose. Mercury News’ August 31st coverage of the boating accident made a major error in reporting the number of annual United States deaths by […]

Propeller Safety History Repeats Itself, Repeats Itself ….

While reviewing the U.S. Coast Guard’s Advanced Notice of Proposed Rulemaking on boat engine cut-off switches (lanyard kill switches), USCG-2009-0206, we noticed USCG included a 2008 review of their BARD (Boating Accident Report Database) in which USCG identified boat propeller accident injuries and fatalities from 2002 through 2006 that could have been prevented if the […]

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 […]

Florida Propeller Accidents Missing From U.S. Coast Guard 2010 Boating Accident Report Database (BARD)

As mentioned in our previous review of propeller accident reporting in USCG’s BARD 2010 database, 7 of the 10 propeller accidents we found news media reports for that were not listed in BARD occurred in the State of Florida.
