Seven curves tangent to the constant V bottom section which define the keel frames shape
The last keel frame is glued up on the garage floor. It will sit half way between D and E frames and is in line with the chain plates. It is the forward most station that has a radius or 800 mm to the outside of the hull and by gluing it up on a lofted set of blocks the design hull shape should be maintained.
To show the family of curves I highlighted the lines scribed on the floor for the photo.
