Below are Top and Bottom snaps of a "Flopper Stopper" we had made in early 1987 for our prior boat, a 1976 Cal
2-29. It measures 18" wide by 24" long with the frame made of 1/4" diameter steel
rods bent to shape and welded together. The diaphram consists of 3/32" nylon sheeting, split in an X-shape as shown. The top and bottom frames are rivited together and a suspension bridle
of 36" long 1/8" stainless wires swaged together around small thimbles connects to each corner and a 2" diameter ring at the center. Suspended 8 to 10 feet deep off the end of our 11' log spinnaker
pole supported with a topping lift
and fore and after guys, the device did a good job of stabilizing our Cal
. Similarly suspended from the end of our 17' long spinnaker pole off the side of our current
yacht, the device does an admerable job. When using such a device it is wise to actually use a snatch-block on the pole end so that the depth can be adjusted. It is also wise to hang a chem-lite or other illumination on the outboard
end and at mid-length so that some unsuspecting person doesn't behead himself in the dark.
