| | Re: Flopper Stoppers...
The flopper stoppers are used a good deal on the West Coast of US and Mexico by cruising boats. They employ a plate or set of plates which offer little resistance to going down in the water, but offer several sq feet of horizontal surface under the water as they come up, with the rolling boat. This resistance dampens the roll by 50% and slows the roll, making a fast roll more tolerable. We like the Magna plates. The "mexican hats" are not perticuilarly good. We have tried them when drift fishing and they work fairly well. But if the boat is moving (wind driven) they can stream aft. Mount them foreward. I would prefer to use a tower or some place well above the gunnel to secure the upper support. You also have to have a line foreward and aft--so that these can get in the way of the fishing gear. We abandoned the use in the Gulf of Mexico, and rarely use them in Calif. currently.
