Barry, I was reading this thread and saw your comment about the "Slap Silencer." You noted it was online, but where?
I have this problem with my 54, but mostly have become numb to the slapping in the aft cabin. The boat came with a very heavy canvas in a bag, and I suspect that is what it is for, but I have never tried it.
Can you provide more details about your solution? Is my bag carrying the right thing, and if so how do I use it?
Phantom, A54 #44
