To use flopper-stoppers on Bonnie Lynn, the 57-foot offshore schooner that my wife, Bonnie, and I launched in 1998, we installed 18-foot aluminum poles that we had specially fabricated for the purpose. We experimented with several types of stoppers, finally settling on a pair of stainless-steel trays that utilize opening and closing baffles. Because the poles are attached at either side of the rig of Bonnie Lynn, which has a beam of 15 feet 6 inches, when the floppers are deployed, they're almost 52 feet apart. If we used shorter poles, we'd need larger floppers. We've used our floppers often in the eastern Caribbean, and they work great.
