ABS makes good plumbing and can bend slightly - more if you "prebend" it
by bending it over a form for a couple weeks and letting it take a set
slowly. So it could likely be made to conform to some hull shapes.

More years ago than I want to admit, I was the marketing director for a
company that fabricated ABS and PVC underground and under-bridge conduit
for utilities...they bent a lot of pipe by heating it, then putting on a
form to cool, which was necessary to preserve the diameter around the
bend. So I'm assuming that unless you have the necessary form, any DIY
bending would have to be considerably less than even 45 degrees...maybe
even less than 15.
