: stop sanding now!!(too bad you started).

: if the rest of the hull is semi ok, just take a razor saw or small saw and
: saw betw the panels again and true up and then restitch, go as far as you
: need to to realign. i've done this a fair number of times. not a big
: deal,just takes a day or 2 to get back to where you were.

I had a similar problem on my Arctic Tern. I used a heat gun ($18) to separate the panels (about a 2' section), realigned, restitched and epoxied and it turned out great. No one will every know...depends on how much you've sanded.
