I think I have the rigidity covered. I used 3/4 ply and lotsa drywall screws.

Are you saying that to set each station at the proper height, in order to get the designed rocker, you measure down from the upper stringline, to the top of each form? I didn't pick up anything like that in KayakCraft - I understood the purpose of the string was to help keep the stations lined up side to side, and the datum for determining the height to set each form was the upper surface of the strongback.

Also - how do you keep a lower string in place during setup of the form stations? Do you cut notches in each of the form risers?
