From the side, you can see the hard chine of this boat.  It should do a edged turn pretty well.

Each of the forms is mounted to the boxbeam with cleats on two sides of the beam.    Normally, you would align the forms rightside up and then flip it over to begin stripping the hull.  However, since the boxbeam was slightly flexible, I mounted the forms in the inverted position from the beginning to avoid any misalignment that could have occurred when rotating the beam.
