MagBlade Propeller

MagBlade Propeller

Recreational Boating Safety (RBS) of South Africa recently announced the new MagBlade boat propellers (MaxThrust & SlipStream) that will fit all outboard and stern drives. Recreational Boating Safety claims the new MagBlade boat propeller is much safer AND provides better performance and maneuverabilty while reducing drag, ventilation, cavitation, and fuel consumption.

Recreational Boat Safety (RBS) accomplishes these things by using aerodynamic principles to harness the potential energy of the water flow. They maximize the use of the surface area of the oncoming “blade face” by reducing the area of the back of the blade. This reduces drag and reduces the area that has high potential for cavitation.

MagBlade Max Thrust also strengthens the impact zone (leading edge of the propeller blade) which increases the life of the propeller. Read More→

McGarrigle v. Mercury Marine was settled today, August 28, 2012. Earlier today Judge Noel Hillman of the United States District Court for the State of New Jersey signed the “Stipulation of Dismissal and Order” in which the parties voluntarily dismissed the case with prejudice against all defendants, meaning the case was settled.

In John and Barbara McGarrigle v. Mercury Marine in the United States District Court, D. New Jersey, John McGarrigle fell from a small outboard powered boat in choppy water in July 2007. The boat went into the “Circle of Death”, McGarrible tried to grab it to reboard, and was struck by the propeller. Read More→

Back on July 27, 2012 we launched on Facebook. Please come by and “Like Us” at Facebook.com/PropellerSafety.

We will be expanding our presence there as time permits, but we have already been able to reach several people we would otherwise have missed.

While our main archive of information will remain over here at PropellerSafety.com, we look forward to making more friends over there in an environment that is a little more engaging and interested in very current topics and events.

See you there!

We have finally made the rounds. In June 2011 after hundreds of hours reworking our old site we launched here on PropellerSafety.com URL as a wordpress powered site. We launched on Twitter in November 2011 @PropellerSafety during our live coverage of the Listman trial. We released a mobile version of PropellerSafety.com in early June 2012, and recently (late July 2012) we launched on Facebook. While there are many other social venues one could setup a presence on, we will focus on these for a while.

Its a bit hard to imagine making it this far from where we were in 2010 dreading the upcoming move to PropellerSafety.com due to all the work involved. We hope you enjoy our new sites and our presence in the social media.

On June 5, 2012, Volvo Penta was issued U.S. Patent 8,195,381 for a Safety System for Marine Vessels. The patent focuses on detecting people in the water in conjunction with digital anchors. UPDATE note – on September 18, 2012 Volvo Penta was issued another patent, U.S. Patent 8,271,155 for technologies surrounding this same concept.

GPS anchors, also known as digital anchors, are computer systems that keep a boat or vessel in place on the surface of the water. They first gained popularity in drilling rigs and have since spread to recreational boats, and more specifically to larger, twin engine recreational boats. The boat operator can punch a button (or touch a touch screen) and the vessel will stay in place based on GPS signals.

In recreational craft and smaller working vessels, sometimes operate with only one person on board. That person might launch the digital anchor then leave the boat and get in the water to tend to the vessel, to tend to nets, to perform a dive, or for other reasons.

If the digital anchor fails, the boat might leave the area stranding the boat operator. The digital anchor might decide to make a correction just as the boat operator is approaching the stern and they could be struck by the propeller. Read More→
