(Having just seen the photo - thank you sir!)
I got a lot of very similar stains in the back of cupboards on my boat. We
worked out that it was caused by condensation in the hollow metal cross members
that supported the roof. This ran down to the open ends where it dripped onto
the back of the panelling. We solved the problem by removing the panels and
re-routing the water. It was never much but the build up did stain over a
number of months. A ground level a water leak caused much worse capillary
staining to the bottom of one panel in a matter of a few days. All the wood
being ply in both cases.
Our boat being designed by us, has a lot of cupboards at the slightly lower
back end and the walls of these (which are 3 ply as opposed to the much thicker
cabin planks used elsewhere) showed up the problem. But...are we the only boat
built with open ended cross beams and, if not, what is happening behind other
peoples side panels?
