strip canoe building problem

Hi all,

I am in the middle of a cedar strip canoe project and could use some advice.  
Last fall I applied and sanded the fiberglass on the outside of the hull.  I
had to quit because of the cold weather.  I installed temporary thwarts to help
preserve the shape over the winter since the inside of the hull is still
unprotected bare wood.  I then literally hung it up in the garage, suspended
sideways from ropes near the thwarts.

Now I'm ready to scrape and sand the inside of the hull to prepare it for
fiberglassing.  Unfortunately, the sheer lines are not a fair curve anymore.  
When looking down at the gunwales from above, there are slight bends where the
middle temporary thwart was.

Shall I proceed with the fiberglass and hope the gunwale strips will pull it
fair?  Shall I try to clamp on temporary outwales while I apply the inside
fiberglass?  Any other suggestions?  Please respond via e-mail to

Thanks in advance,
and not looking forward to a boat with wavey gunwales.

Bob - I unfortunately don't have any solution to your problem, but if
nobody else here has any answers you might try posting to
http://www.by-the-sea.com/newfound/wwwboard/wwwboard.html a strip building
bulletin board at Newfound Boatworks.  Good Luck.

Why not proceed conservatively, sort of "fail-safe"?  Clamp on a temporary
outwale, maybe a little stiffer than the plans call for, and glass the inside.
You may never know whether this extra step was necessary, as my guess is that
the permanent gunwales will pull a wavey sheer into fairness anyway.  A small
price to pay for a little insurance of the old peace of mind.  You could even
use the stock you had planned for the permanent gunwales.  Don't forget to put
packing tape or something between the 'wales and the canoe, or you might find
you've already installed the "permanent" ones!

Good luck,

BTW, please let us know what you decide to do and how it works out.  This is
the kind of information that is most valuable to share with the list.
