Just curious if anyone has tried to line the inside of the hull with noise deadening foam to quiet the waves slapping stern.

Haven't tried from inside but using those swim noodles in the water around the transom seem to help

Several years ago, we bought a device called the Slap Silencer. Sorry, have lost the name of the vendor, but it has been a world class product. Quick and easy to deploy and retrieve and it completely eliminates the sleep depriving stern slap. I have no connection with the vendor, but it is one of the best additions we have added for our evenings on the hook.

I've never had stern slap when at anchor.

I agree with the pool noodle idea. Do a search on pool noodles and read some more, discussed many times. $1 investment at Dollar Store. :soapbox:

Yes, I used top liner and glued it down around the rudder post and aft. Results were less than noticeable. Tried two noodles, maybe I didn't have enough. Hard to keep them under the stern and/or fouling the rudder. We get slap at anchor and at the slip, it just has to be the right size wake to make the slap.

Our First 36.7 has a wide transom with a very wide flat bottom for the last 1/3 of the boat. A particular wave action on the bow will set off a very nasty slap. Perhaps the Jenneau is the same.
