Our Earlier Propeller Safety Inventions

We created this Propeller Safety Inventions category in August 2011. I am listing some of our earlier inventions and linking to them here. We will be posting our future inventions in this category. If PGT<2011 is beside the invention, more can be read about it on our Pre 2011 Propeller Guard Technologies page at 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 […]

Litigation Testing Continues in Testing of Propeller Guards by Mercury Marine / Brunswick

Litigation Testing of propeller safety devices was defined by Stephen Bolden, author of Motorboat Propeller Injury Accidents, as “…manufacturers, in performing litigation testing, are not concerned with gathering information for the purpose of redesigning or improving a guard; rather, they are concerned with simply reporting on whatever propeller guard deficiencies they are able to demonstrate […]

Does the Risk-Utility Test Exception for Simple Tools Apply to Boat Propellers?

In mid 2011, Brunswick requested a rehearing of their appeal of the Jacob Brochtrup propeller injury case in front of the U.S. Fifth Circuit Court of Appeals. Brunswick feels the original court (U.S. District Court, Western District of Texas, Austin) did not force Brochtrup to prove the design of their boat was unreasonably dangerous under […]

Use of Wordles in Studying Propeller Safety

Wordles are a form of word art. They display the frequency of use of individual words in a passage of text by the relative font size of the word in an image. The individual words are displayed all jumbled together in colorful, eye pleasing collection of fonts and colors. As we view wordles, we begin […]

The Emperor Has No Boat – SUNY Propeller Guard Testing

CED Investigative Technologies, Inc. has been testing the human factors of propeller guards at State University of New York (SUNY) Buffalo at their Center for Research in Education and Special Environments (CRESE) facility. Some may recall, this is the same facility used by Mercury Marine and Outboard Marine Corporation to test a propeller guard back […]

Propeller Guard Information Center Launches PropellerSafety.com Today
