Re: roller stabilizer or flopper stopper
Mine are about 18" in diameter, the kind you can buy at a marine store. There's 4 along each line, about 4' apart, with a weight at the bottom. The crucial part is the weight at the bottom - that's essentially an anchor that isn't stuck in the ground but counter-balancing the motion. It has to be really heavy.
They don't work that great in choppy or rolly spots. Probably help to keep the boat stable in stable conditions
