Lofting of the hull to full size was carried out in the usual way. In this
case the profile, waterlines and buttocks were faired on a concrete floor using weight
to hold the battens in place, while the sections were lofted on an area of portable
wooden flooring as seen in Fig. 1 By making the lofting of the sections portable, it
was possible to readily compare dimensions taken from the profile and waterlines with
those of the sections and, when the lofing was completed, move the wooden flooring to
a convenient position for the bending of pipe frames
