Re: Stus-List Bulkheads separated from cabin top (C 34)
Are the photos while underway or at the dock? If at rest you might want to check the shroud and stay tension as you might be deforming the hull and lifting the deck even before bashing to windward. That being said even our 38 Landfall will flex but only noticeable at the forward bulkhead where neither top nor bottom are tabbed near the doorway.

Re: Stus-List Bulkheads separated from cabin top (C 34)
My 1978 C 34 (#117) is the same. The bulkheads are tabbed to the hull. The
headliner is glued to the deck before landing the deck to the hull. There was
some (loosely) adhesive applied at the top of the bulkheads, but it is really
meant to "float" against the deck. Most of the time the squeaking you hear is
the bulkhead rubbing against the headliner. If yours is like mine, the
clearance between the bulkheads and the headliner is pretty tight.
To keep the deck from flexing too much, there are several mechanical
attachments, as others have noted.
1. The mast tangs connecting the mast to the partners2. A T-fitting bolted
through the deck and to the starboard main bulkhead3. Wire shroud at the
forward end of the head bulkhead on centerline. This is attached to the
forward end of the keel grid and then through the deck and babystay track. It
should have a turnbuckle at the bottom to tension.
I actually don't have as much movement as your pictures show, but I do have a
little.
Have fun sailing!

Subject: Stus-List Bulkheads separated from cabin top (C 34) Hey all - Last
week while S.V. Safari was bashing upwind offshore en route to Tofino BC I
noticed that the forward bulkheads were creaking. Upon closer inspection I
realized that they had separated entirely from the cabin top by moving inboard
about 1.5cm. Here’s the port bulkhead: http://imgur.com/Meqa58IAnd here’s the
starboard: http://imgur.com/MIZHoiG The ends of both bulkheads are prevented
from moving farther inward by the termination of the slots in the fiberglass
ceiling that they’re nested in. You can see in the photos that they were at one
point glued in. The bottoms of the bulkheads seem to be very well fiberglassed
in to the hull, and there’s no sign of breakage along the lower parts. The
bulkheads that form the forward walls of the hanging locker and bathroom are
also separated too, by what looks like the same amount. Looking at previous
photos it looks like they’ve been like this since before we bought the boat.
They’re not loose at all, they seem very well set in place. Questions:1. Is
this a common problem?2. How in the world would we fix this?3. How critical is
it to fix this immediately? Were we courting disaster to push the boat hard
offshore? --

Re: Stus-List Bulkheads separated from cabin top (C 34)
Andrew, I get a bit of squeaking between the top of that bulkhead and the underside of the deck when in any kind of sea. A friend who grew up sailing on a 35-1 told me they used to put beeswax in that joint to quiet it down. Not sure if you could anything in there, but might we be worth a try.

Re: Stus-List Bulkheads separated from cabin top (C 34)
Hi Andrew As near as we can tell, the upper bulkhead is not bonded to the deck – and for a reason. C’s do flex a bit as they sail – especially as they bash to windward. The lack of this bond allows this flex to happen – all well and good as the stresses are dispersed throughout the entire hull. That said, the flex is moderated / controlled by a stainless “T” tang that is attached by bolts through the deck and also through the bulkhead.

Re: Stus-List Bulkheads separated from cabin top (C 34)
Hi Andrew, I have a similar looking issue on my 1978 C 34, Also have very slight dimples in the hull at the same places. I've never sensed movement, and thought not as much as yours, I can see that my bulkheads are not set in as deep as they may have been at the build. Aft sides of the bulkheads are tabbed in and I see not signs of movement there. Heavy back-stay, and the odd big wave also make the boat creak and/or groan, but so far I have not felt there was a danger. My Chain-plates are dry and solid. There are a coule of spots on the deck that need attention, but neither are much bigger than a dinner plate. Interested to see comments from others as well. My survey a few years ago found nothing to fear in the hull or deck.

Stus-List Bulkheads separated from cabin top (C 34)
