    lazaroo

    I'm crazy and I overbuild (see the Gallery.)
    On 338 that bulkhead was VERY badly fitted. I had access under the cockpit and could wedge myself up close it. The factory had glassed it badly as well. They had bridged gaping edges with tabbing, or not at all - I found still raw (white) fabric and roving under the inside of the deck. They had only tabbed it, the rest was unseald plywood. No rot.

    I glassed the surface and retabbed the inside,
    [where I also reinforced the rudder tube.
    I believe water also got in at the under cockpit sole/rudder tube join. There was NO reenforcement there.]
    Now that I think about it: The cockpit sole flexes, therefor seal that joint with rubber.

    Also did the same in the laz.
    Can't remember if the bulkhead was glassed over or just tabbed. I think DFO's trired to seal it with doubtful remedies.

    While I noted some rot-like deterioration of the plywood decking in the laz, none was found on the bulkhead - even where the sodden foam was. My suggestion for this phenomenon is that there was prpbably saltwater encapsulated under the decking - but the little deck was more prone to fresh water accumulation.
    It should be glassed imco, especially now that you've open it up to expose the 'V'.
    I'm for glassing to tie it all together and extra epoxy sealing insurance.

    Found that I could reach up thru the well hole standing outside. That helped...sort of... could see up under there, get an arm in - instructive! Scrape out ancient dribbles of frozen snot, find where the top of the paper pattern should be, or push sticky wet fabric in place. Cuss-n-carry on.

    Like I say, I believe in paper patterns which allow you to cut the glass fabric pretty precisely. And I like the X-matt stuff because it stays stiff like cardboard when dry - and if you decide to put it in wet, if you're carefull, it will keep its shape. Even if darts have been cut into it to get it to fit in corners. Totally different thing than woven fabric. And if you've marked reference lines on it you can position the stuff exactly how your paper pattern said to, wet or dry.

    That end of the cockpit bulkhead has had a history of leaks for OB people on the Forum - it is an always wet lazarette It even leaks across the TOP under the sheet traveler bridge. So I double sealed the damn thing.
    I also incorporated the whole end of the cockpit inside - since I believed the cockpit could use some more support - by closing off most of the space between the cockpit well and the bulkhead. Crazy, I know!

    But leaks now? HAH! Don't think so!
