Ilhan....paper can distort by changing moisture environments...however...

If you consider that the Elevation Plan is not distorted as evidenced by the
2 red circles on the hull vertical edge, then it is reasonable to accept that the same Elevation view of the outboard vertical of the Paddle box, marked with the
2 red arrows on the same Plan is not distorted
I have certainly not seen any examples of such Drawings.......so up to you
