MIK - It's my fault for not reading the note on the drawings which makes it obvious that the sides are not reflections. I get frustrated when a machine shop does not read a note I place on my drawings so this is nothing new :U
If I had seen the note, a solution is to flip the cut side when using it as a template so the two sides are mirrored. I think there is enough ply margin to make this work but have not checked for sure. Worst case the butt joint on one side would be off by a few mm but as long as the two hull sides are cut the same that should not matter.
