I know of an old kevlar racing canoe that's been stored upsidedown on

side up with logs in the center? --JP

Hogging (the process where the water bouys up the beamy center of a
boat, but not the ends) is hard to defeat (and is the shape you describe
here). I don't know how kevlar might respond to attempts to reverse the
effect, but the hull is not likely to ever resume its natural shape even
if bending it back is somewhat successful.

On a historical note, the USS Constitution had been floating since its
launch in the early 1800's and developed a significant hog to its hull.
During the refit done in the 80's or 90's, I forget which, most of the
old lumber had to be replaced to counter this effect. There was an
article on how they repaired this for its sail up and down the east
coast in National Geographic a while back.
