Propeller Fatality Tax, Cap and Trade Background Information

We discuss Propeller Fatality Cap and Trade With a Tax on Over Cap Fatalities as a means to reduce recreational boat propeller fatalities in another post. While developing those concepts, we explored some other venues as well. The less desired approaches are provided here as reference material. In general, they present an approaches similar to […]

BARD Reported Accidents by Outboard and Sterndrive Manufacturer Used to Estimate Legacy Drive Population Market Shares

We are working on a propeller safety proposal that requires an estimate of the percentage of U.S. outboard and sterndrive boats powered by the various outboard and sterndrive manufacturers that are in the field, called the boat park by other nations. These numbers may be considerably different than current market shares due to some manufacturers […]

Call for Student Propeller Safety Project Sponsors

We have seen some great student propeller safety research projects through the years. In an effort to encourage more college students to consider propeller safety projects for Senior Design Projects, Project Classes, Senior Thesis, Capstone Projects, and Thesis, we created a post to attract them, Research Projects for Senior Design Classes, Masters Thesis Projects, & […]

Cushioned Propeller Guard – Senior Design Project

Marine drive companies have long employed damping / cushioning technologies to protect marine drives, most typically trim cylinder log strike systems that allow the drive to swing back, up, and over underwater obstacles. Recent years have brought several through hull drives to the market, most prominently Volvo Penta’s IPS, and Brunswick’s / Cummins Mercruiser Diesel […]

USCG BARD as a Tool for Boating Safety Continuous Improvement

The U.S. Coast Guard BARD (Boating Accident Report Database) is a vehicle for driving continuous improvement in boating safety, however, it is not being widely used. We suggest all boat builders closely monitor their boats in all kinds BARD reported accidents, develop and test solutions where needed, and use those solutions to continuously improve the […]

Estate of David Paul McFarlin and Jamie Laass vs. Brunswick Corporation (Mercury Marine and Lund Company) and Others

A young boy, David Paul McFarlin, was killed in a May 31, 2010 Storm Lake Iowa boating accident. A Labor Day boat outing on Storm Lake became a tragedy when their 175 horsepower Mercury Marine outboard motor struck a submerged dredge pipe on Storm Lake, the Mercury outboard flipped backwards into the boat, and David […]

Estimating the Total Number of Propeller Accidents: A Senior Design Project

Safety professionals turn to the U.S. Coast Guard Boating Accident Reports Database (BARD) to find the total number of recreational boat propeller accidents reported to USCG. USCG acknowledges some propeller accidents go unreported. The boating industry claims the more severe an accident it is, the more likely it is to be reported, propeller accidents are […]

The Drake Equation vs. the Probability of Being Struck by a Boat Propeller

We recently completed our Developing a Consumer Guide for the Selection of Propeller Guards and Other Propeller Safety Devices post. Part of that project involved creating our Propeller Accident Risk Worksheet. In that worksheet we identify five categories of Propeller Accident Risk: Boat Specifications Risk– some boat types are more likely to be involved in […]

Developing a Consumer Guide for the Selection of Propeller Guards and Other Propeller Safety Devices

This propeller guard selection guide is NOT ready for use. As brightly emblazoned on our documents, they are rough drafts. We posted them to generate a discussion that could improve them as well as provide some ideas to those working on the U.S. Coast Guard’s recently announced efforts to produce a consumer guide to propeller […]

History of Lanyard Kill Switches for Recreational Boats: Inventions, Regulations, Accidents, and Trials

Although the U.S. Coast Guard is still considering regulations that would require boat builders to install kill switches (emergency engine cut-off switches) in all new recreational boats below a certain length and separately considering making their use mandatory, they have been on the market for over 30 years. The basic problem of unmanned boats going […]
