What exactly is Rescu Swim'r and how does it work?


The Rescu Swim'r is a deployable device that mounts to a ring-buoy. When the PFD is launched, the Rescu Swim'r deploys a rudder downward that makes the PFD tow at a 45-degree angle to the boat. Then as soon as the boat slows or is turned toward the man-overboard, the PFD immediately runs a slow-moving catch-line 90 degrees to the boat. The victim is contacted by the line/PFD on the first pass, almost without fail, and without bringing whirring steel propellers, or a bouncing multi-ton hull, near enough to ever harm them.

The Rescu Swim'r attaches easily to a life-ring buoy via two straps. All throwable devices are supposed to have a length of line attached to them and to the vessel so that the PFD can be pulled back to the boat after it goes to a victim.


    

"Deployable" means that when the PFD is stowed against a bulkhead or on a rail, the Rescu-Swim'r is attached to it and stays folded flat.  When folded up the Rescu Swim'r has a looped-securing-strap that runs through holes in both the mounting fin & rudder fin. A half-loop of your town line then sits in this looped-securing-strap to keep it in place. As soon as there is any tension at all on the tow line (i.e the buoy is put into the water undertow), the half loop of the tow line pulls out of the looped-securing-strap, which makes the looped-securing-strap then pull out of both fins of the Rescu Swim'r. This allows the Rescu Swim'r to pop open and begin guiding the PFD to a position beside the boat.




It is not nearly as complicated as it sounds. It's actually simple mechanical & hydro-dynamic principles arranged in a way that changes the process of recovering a man overboard from a very dangerous and difficult task, to a safe, quick, and easy task.  

Why do I need a Rescu Swim'r? 

Currently, the accepted method of getting a Type IV PFD to a man-overboard is to throw the PFD into the water, tow it toward the man-overboard, pass them then turn the vessel around them until the device gets to them. This maneuver is very difficult to execute and many operators can never achieve it. To even have a chance of accomplishing it, an operator must run the boat VERY closely past the victim on the initial pass before the turn. Just operating a boat this close to a person in the water poses an extreme risk to their safety. 



What generally happens with a less-experienced or panicked operator is that he/she will logically pass the victim from a safe distance (rather than the requisite 'extremely close' pass), then start to circle around the victim. This won't work. Once in this pattern, the PFD will NEVER reach the victim. It's been called the “Circle Of Death”. A common last-resort response to the Circle of Death is to stop the boat, and back it down toward the victim, a dangerous maneuver that ends in a line-fouled propeller AT BEST.


Experts estimate that 1 in 5 drownings are fatal in the first 120 seconds (often due to cold-water shock effects). That's just 2 minutes. The Rescu Swim'r gets life-saving flotation to an underway man-overboard consistently in just over 1 minute. Regardless of the boat operator's experience level. This device enables someone with zero boat-operating experience to get life-saving buoyancy (a Type IV PFD) to a man overboard quickly, reliably, and safely.


In our product testing to date, it took an average of 1 minute & 14 seconds to get a PFD to the passenger USING Rescu Swim'r. Without using Rescu Swim'r it took an average of 9 minutes & 51 seconds! A dramatic difference to be sure. But consider these times in light of the FACT that, in cold water, not even the best swimmer can make meaningful movements (much less swim) with their limbs after about 10 minutes.


The above graph represents the likelihood of an overboard passenger surviving as time in the water passes. This outlines the importance of each second in rescuing a man-overboard. Overlaid on this graph are the average times that it takes for that passenger to be rescued with and without Rescu Swim'r. It is clear from this, that an overboard passenger is drastically more likely to be rescued alive using Rescu Swim'r, compared to going without it.


This graph can also be read as representing the ability of a person to re-board the ship after being pulled to it using a PFD. After just a couple minutes, a man-overboard in water of colder than 60 degrees Fahrenheit begins to lose the ability to grasp anything, and soon thereafter will lose any meaningful movement of their limbs -- thus becoming dead weight for a potential rescuer. We have lost many a boater who was lashed to the side of the boat, unable to be brought out of the water. Using a Rescu Swim'r will get flotation to the man-overboard sooner, which increases the chance of them being able to re-board the boat safely. A Rescu Swim'r will get them back to the boat while they have nearly all of their coordination and strength left.
