I'm not familiar with the layout of the LF38, but, FWIW, on my 35-1 I
have found (find....) water outboard of the panels under my quarter
berth and also under the settee, and the source is the joint between the
hull and deck. Once I tightened up the nuts/bolts that hold the toe
rail and the joint together, the leaks stopped. Just have to be
careful not overdo it and squeeze out the Butyl sealant, but it's kind
of a routine maintenance job.
May have happened on your boat in the past.

So I'm doing a lot of projects lately, and was majorly bummed out to
find the wall between the engine compartment and the lower foot of the
port aft quarterberth has some significant rot. Frustrated because
lately it feels like every project I fix, I find a new one. And this
will be a big one.
Please see pictures here:

As they say, pictures are worth a thousand words. It's a 2-3 foot
section of the port engine compartment wall, abutting the storage
compartments under the port quarterberth.
One thing I'm perplexed on is - how did this happen? There are no
leaks dripping onto this area as far as I can tell. The cockpit is
above this and it doesn't have any major penetrations on this side.
And the top of the bulkhead is solid. Normally when wood rots I expect
it to start from the top, where the leak is.
The only clue I have is this bulkhead had two cuts / gaps in the
bottom (probably to run wires through) and that's where the rot seems
to have spread out from. So maybe the moisture got in through the
exposed grain at the cut? There is high humidity in the engine
compartment due to inevitable moisture in there. But also the rot is
right behind the batteries (house #1 + starter), which I find
suspicious. Is it possible the gel cells outgassing actually caused
the damage somehow?
From the pictures do you think this might be "dry rot"? (a
particularly evil kind of rot which apparently spreads by fungus even
without an active water leak anymore)
If it's spreading I want to cut out the bad portion of the bulkhead
and glass in new wood asap. If it's not spreading I can put it off, or
even ignore it since it's not structural. I could even just paint over
it with new waterproof marine paint? If I have to cut it out, access
will be tough - it's in the engine space, I'll have to remove the
batteries, some wiring, and probably the exhaust lift riser, and the
panel that covers the aft quarterberth storage compartments.
The other thing is I can't even tell what kind of wood this was
originally. It doesn't seem as strong as marine plywood or the wood
used in other bulkheads. The bad wood seems sort of grey / bluish
colored - I'm not sure if that's from the flaked off white paint or what.
The other option is trying Git Rot injected into holes drilled into
it. http://www.boatlife.com/git-rot/
At this point mainly wondering if any of you have experience with this
issue, particularly in this area (non-structural, between engine
compartment and aft qtrberth storage compartments) or how something
like this can happen (rotting from the bottom up rather than top down)?
