How It Works

 

The Everlasting FlopStopper™ is essentially an underwater horizontal Venetian Blind.  On the “down-roll” the blades (“blind slats”) open and the FlopStopper sinks without resistance.  On the “up-roll” the blades close and create a solid platform with 8.4 square feet of resistance, thereby slowing the up-roll and dampening the side-to-side rolling motion of the boat.   


ALSO, the delayed up-roll takes the boat out of the wave cycle/ pattern, so the boat “cancels” the next wave instead of rolling with it.  It really works!


Even the slightest motion engages the wave-dampening mechanism -- the blades open either slightly or fully, depending upon the size of the wave/ motion.  All other types of “Flopper Stopper” on the market require a large (uncomfortable) wave/ motion before they engage/ begin to function.
