I have the Magma flopper stopper and find it works fairly well. It gets deployed whoever we anchor unless is perfectly calm. I use their 8 foot telescopic outrigger to extend the reach rather than mounting it off my sail boom.

I measured my roll motion with and without the flopper stopper while at anchor. I found it reduced roll from an average of 18 degrees to 4 degrees. Mounting it directly onto the midship cleat, the effect is noticeably less, perhaps 18 degrees to 10 or 12 degrees (although I didn't measure it.

There is considerable stress on the rigging, so ensure whatever you use is heavy duty. I beefed up the Magma flopper stopper by thru-bolting the hinges as they were just spot welded in place.
