I spent a few hours out there this Saturday. Jeff, a friend at the marina with a 28' lapstrake Owens came out with me to check up on his boat and hang out.
We were able to remove the galley countertop and cabinets without damaging things too much. With it out of the way I can access the bad sole and the side decks supports.
For reference, the pix below are of plywood that's just forward of the dinette (in the nice Coho interior pic) that also serves as wall of the galley cabinets closest to the stern.
This is looking up showing how its attached to the wood underneath the side decks. This is not tabbed to the hull or attached to anywhere else and from what we can tell simply sits on the sole. Since the sole has softened this board has sagged, allowing the corresponding area of the side deck to sag as well as the galley cabinets.
Looking downwards. Doesn't show much but again it isn't even attached to the sole directly (though with all the "nailer" boards and all those silicon bronze screws, its pretty well attached to the cabinetry which itself is attached in a lot of other places in the boat).
It seems these boards do little to support the cabin superstructure and flybridge. We concluded that most of the support comes from the plywood planks (probably not the right term) inside...going back to the nice Coho interior pic, they're the boards behind the microwave on the starboard side, the curtain rods near the top, and if you look in the mirror above the galley, there's a lamp attached to the one on the port side.
I need to remove the cabinets on the starboard side opposite of the galley and will continue to proceed from there.
Behind the galley and underneath the side decks the backing boards were screwed from the outside inwards. Jeff suggested that when constructed that everything from the gunwales up was prefabricated and dropped into the hull...sound about right?
Were Commanders constructed in this fashion, even remotely?
