Ok - not from the diesel as you suspected but from small waves (or large ones too) trickling down the aft section of the boat while on anchor or at the dock. I recently had friends to the boat for a weekend and when I asked how they slept - :( - not so good was the reply. The aft cabin is noisey they claimed. I kind of blew it off - knowing that our boats aren't much for light sleepers and there always seems to be noise happening somewhere.
Well - later that week I happened to be routing some wiring for the new chartplotter - AND HOLLY COW - it was like an echo chamber back there. Trickle, trickle, trickle- but louder than you might expect. It appears that at the dock we get some light wave action that hits the stern at an angle that creates the noise and the hull amplifies it.
My first mate and I sleep in the bow so don't notice it but I'd like to abate that noise somehow so our guests sleep as well.
Any ideas out there?

I read somewhere to tie those floating 'noodles' around the waterline at the stern. Never tried it myself, but I've never had that particular issue and we sleep up forward.

The noodles are a great idea. There are "marine" versions at lots more cost, of course.
Or you could anchor out more, rather than staying at the slip.:)

I rarely spend the night in the slip, but when I do.... My slip is on the last pier; I come in stern first, with the bow facing south, into the cove. The boat in the next slip is a Hunter38, with a very broad, flat stern. When the wind is from the south, the wavelets slapping under his stern keep ME awake. I may buy him some noodles ;)

On the rare occasion when bothered by this (last in Pender Harbour, BC, in 2006) I had enough room to secure the dink across the stern.

Unfortunately - I just gave away all my floaty thing - noodles. But they are cheap to replace and definitely worth a try. Stu - as to anchoring out more - gotta work on that one too! We do seem to get attached to that dock way to often. LC - I have to keep the Dinghy hanging in the davits to keep the snakes away. They love a sunny warm place in the spring!
Thanks guys!

I'm with Larry on this one - if you've got a dink, you can line it up to break the ripples. Beats carrying foam tubes around in my opinion.
On the other hand - I actually LOVE the sound of the water lapping against the hull back there. Totally soothing, part of the experience...
Maybe if you prepped your guests to expect it (look forward to it), they'll see it as a romantic part of staying aboard and sleep like babies... ;^>
