OK-I wasn't sure if epoxy would bond to the foam.  I generally don't have standing water, although after a storm I do get a little but until I'm at the boat.  I think weather strips around the the stern hatch per this thread would help.

On the deck seam-interesting.  Not an area I've spent a lot of time thinking about or working on.  I would think any water that could possibly come in through the rub rail would just drain down to the stringer then back to the stern and bilge.

Epoxy bonds better than other resins.  Just be sure to rough up the surface before coating.  The hull deck seam is subject to a lot of stress, and depending on the model year different adhesive/sealants were used.  My 1979 CCP had unsealed holes(for injection of foam), so any water that made it past the rubrail had a direct path into the liner.  If you think about it, as your boat cuts through the seas, water can be forced up into the hull deck seam.

Interesting.  Now I know why I have a few holes in my stringer fiberglass encasing, they must've been for injecting the foam.  I knew the PO was not proactive enough to drill and test foam.

Is this flotation foam or foam inside the stringers?

Correction.  Took a look last night before heading out fishing.  This is flotation foam, not stringers at all.  Not encapsulated in fiberglass, just foam on the corner of hull.  Now I'm a little concerned.  There is also a little moisture in this foam where is meets the bottom and sides of hull.  Likely some water dripping in from rub rail as someone else mentioned.  When I first got the boat 6 years ago the PO had siliconed the rub rail to the gunnels in an area where it was pulling loose, probably from an impact....  :c002: I feel like I've been paying for all the screwups of the previous owner who beat the hell out of this boat
