The drawings don't show butt blocks where the side panels need to be
extended from 8 to 10 ft, and there isn't enough wood to lose any inches
on a scarph (thank christ, I don't want to learn that little skill on
this project).

you might be expected to use a taped fibreglass butt join. very common.
stonger than plywood. lay resin impregnated fibreglass over the join
and let cure. optionally turn over and tape other side of join. check
building instructions.
