: So you pulled all the wires and then re-stitched them, starting at the ends

No, I brought all the stitches together with panels 1/2" apart, then tightened them till they were 1/4" apart, then 1/8" apart and then got the ends perfectly matched and tightened them together.. and worked from there towards the middle... till all were making contact...

I was
: thinking of doing the same, because the stern end of the center hull

: difficult to wire in the bulkheads as instructed and the stern bulkhead
: wants to sit at what looks like a slight tilt and a tad off-center (the
: other things look fairly straight at this point). Both bulkheads were a
: little warped, not completely flat. Is this something to worry about? The
: kit instructions imply that the bulkheads give the boat its shape.

If they are fairly bad, it will make the hull narrower. If the warp is minimal, it shouldn't cause too much havac.. If the hull panels are pulled together as I mentioned, the warp can't move them.

I get rid of warps in plywood by laying it down on a grass surface or something damp ( not wet ), with the bow up. This allows moisture into the tight side and out of the loose side. It will flatten out... unless it's coated with some sort of sealer.. Those bulkheads aren't too big, so you could probably wipe them on the concaved side with a damp rag and lay them down on the bench.
They should flatten..
