#7729--BUILDING A STABILIZER 
("FLOPPER STOPPERS")
For more than a century, various kinds of devices have been used on boats to reduce the rolling action caused by waves. The most successful stabilizers are movable fins, but they are used only on ocean liners and large, expensive yachts. Many complex systems have been developed but a simple way is to use a pair of sea anchors with weights to hold them down and add stability. This "flopper-stopper rig consists of a pole rigged at right angles from each side of the boat with a sea anchor and weight hanging down from the end of each pole, several feet out from the boat. The farther out the anchors are placed, the more efficient they will be.
