    Aft bulkhead repair/replacement

    Tore out our old tackle locker and found the bulkhead pretty well rotted. Mostly the sides but also behind the bait freezer and under the window. Anyone done this project? Looks like it's 3/4 and 1/2" ply laminated together. The top of the ply is tabbed to the bridge bottom but I can't tell where the bottom ends. Look like it's supported by the deck and goes into a pocket on the return flange on the deck. I'm betting Cricket has been here before.

    Re: Aft bulkhead repair/replacement

    I have replaced the lower part of the wall on my 42C. On both sides of the door to a height of 12". The rotted plywood stopped at the bottom of the door and it rests on the bulkhead coming up from the hull which the cockpit liner is screwed to.Luckily that bulkhead was in perfect condition. The hardest part for me was removing the rotted areas. I used a router and jigs to get a uniform depth for the new wood. It would have been easier to just cut a 12" strip from the bottom and separte the interior wood from it for reuse with the new wood. I did not find any tabbing holding it along the bottom but it was screwed into the cabin floor along the bottom just above the cockpit liner. Fixing under the port aft window was much easier as the rot was not as bad. When I was done with window I caulked between the trim and glass to prevent water from running down the glass and into the wood under the window. I'm sure there was better way to do this but I was happy with my repair after repainting and getting my cabinets back in.

    I hope this gives you some insight,

    Time for the mezzanine install???????
    Luckily we haven't had any rot in the aft bulkhead, have cut it twice on the port side from the door over to just past the window to remove the engines.
    Way back we glassed the bulkhead to the house which is what probably saved us, and removed the windows, sealed with epoxy also. Can't exactly remember how the bulkhead cockpit floor joint looked like when we ripped out the cabinets and step to put in the mezzanine.
    You could be correct the the cockpit floor sits on top of the aft bulkhead and the the aft wall starts there.
    We did repair a crack several times under the door sill before we put the mezzanine in. The cockpit floor was cut out for about 18" from the bulkhead aft so the mezzanine boxes could be deeper since there was just dead space underneath in the lazzarette.
    All of that was reinforced with wood and glassed back with epoxy.

    When first cut, before the start of cleaning up the mess.
    We wanted to add a lot of storage which is why we cut the deck, especially the refrigerated boxes (4) which can either a fridge or freezer depending on temp setting. Went into the project to be able to drop in a regular chest freezer to both save money and easy replacement. Ended up going all in after contacting Sea Frost for the price of the stainless lined boxes and rest of the components.

    Wow that was extensive, makes me glad I found mine when I did. That just looks heartbreaking.
