How to Sort Through All the Existing Propeller Safety Device Possibilities:

In the past several approaches have been evaluated by the U.S. Coast Guard or independent groups. Typically they select an approach and several of the objections listed above (mostly performance, handling, efficiency variables) and rate several drive types or boats on those characteristics and produce a table similar to the Comparison Table recently produced by IntelliJet Marine, Inc (formerly Marine Jet Technology Corp.).

The Coast Guard tends to pick a few sizes and horsepower ranges of boats and test them for variables like top speed, fuel efficiencies, handling, then rate each combination with various protection measures installed.

The rating system can be improved by weighting the individual variables, but it becomes pretty subjective if you begin to consider broader applications.

We are currently working on some tools to help individual boaters sort through the various propeller injury protection devices to find the best approach for their situation, plus make them aware of other things they can do to reduce their risk of being involved in a propeller accidents. You can see the status of our efforts at Developing a Consumer Guide for the Selection of Propeller Guards and Other Propeller Safety Devices.
