U.S. Coast Guard emblemThe U.S. Coast Guard National Boating Safety Advisory Council met for its regularly scheduled NBSAC 95 meeting April 21-23, 2016 in Arlington, Virginia.

Minutes of that meeting were posted in October 2016.

We have spent considerable effort in recent years encouraging NBSAC to:

  1. Recognize outboard motors are breaking off and entering boats with their propellers still running after striking floating or submerged objects, and that this accident scenario is often associated with bass boats.
  2. Increase awareness level of this accident scenario

As we recently closely read the April 2016 NBSAC meeting minutes we noticed they did mention this accident scenario, but they described it in a manner we have never seen or heard before.
We find that quite odd, since several members of the committee and other industry representatives present were well associated with the problem.

Back in July 2016, we posted a chart for use in designing and testing outboard motors in a way to prevent them from breaking off and entering boats when striking submerged objects.

Today we are posting an updated / enhanced version of that chart. The new chart specifically identifies three more potential design / testing paths to achieve the objective.

We were thrilled to see your entry into the wireless lanyard / kill switch market in the United States.
We recently posted coverage of your MOB+ device after which I dropped you an email asking you contact us after the Miami International Boat Show in response to a few questions we had. My email quickly received an automatic response and yeterday we were contacted by a gentleman in Norway who included a couple others in the email conversation, including a gentleman in the U.S. The email was very informative and inviting to learn more about your product.

We will visit with you after the boat show about our questions specific to MOB+, but thought of several more general topics related to kill switches we would like to share with you that might be of interest to others as well. So I posted this portion of my conversation with you here as an open letter on the topic.

Much of the content of this email will come from some of our previous posts on these topics. Read More→

We have been following the rising waters in California which the industry was first touting for the additional sales it would generate as many lakes had been down a while depressing marine sales there.

Now as waters continue to rise, California faced/faces continuing issues at the Lake Oroville Lake spillway evacuation, and now the United States Coast Guard is said to be planing to issue a debris warning for San Francisco Bay today.

ABC News 7 of San Francisco released a video when they learned of the debris warning planning to be issued Wednesday 15 February. They note much debris is still floating down into the bay from the Sacramento Delta.

We cover the hazards of marine drives striking floating debris on PropellerSafety.com including the possibility of outboard motors breaking off and flipping into boats while still under power when striking floating debris at speed.

We suspect high waters will increase debris in many California waters, especially impacting bass tournament fishing. We encourage everybody to be extra safe out there and lookout for debris.

We will post the debris warning when it is released.

Meanwhile, Pressure-Drop, a sailing forum, has some great satellite, aerial, and on water photos of the status of the region. The also have a nice discussion of flow rates at the bridges and how and why they differ at the surface near bridges.

Fell Marine will be showing MOB+, their wireless kill switch at the Miami International Boat Show this week per their 8 February 2017 press release. They will be in the Fugawi Software booth and have two center console boats on the water in Mag Bay Yachts slips.

MOB is a popular nautical abbreviation for Man OverBoard.

Fell Marine has partnered with Mag Bay Yachts of Adelanto to install MOB+ on all their future boats.

Fell Marine is a subsidiary of a Norwegian firm, Fell Group AS.

Fell Marine’s MOB+ literature repeatedly touts its electronics do not interfere with existing systems on your boat or other wireless systems.

They say their product brings style, design, and comfort to this market, and their system can be restarted by those remaining on board just 6 seconds after someone has been ejected. Read More→

Over the years we have seen many boat propeller warnings that were not as effective as they should have been for all kinds of reasons. Over the last 40 plus years I have looked at thousands of warnings on many kinds of equipment and none of them have ever made me sick.

All that changed Friday 3 February 2017 when we walked the Tulsa Boat Show and my eyes encountered the warning below.

Just attempting to read the warning while the boat was sitting on the trailer made me nauseous. I called Lora over to try to read it, she looked at it and turned toward me with a very perplexed look on her face. Read More→
