In and under view of bow of boat

Aluminium sheet folding declaring definitive shape

Here one can see the curves in the bow of my design. The shape of the whole boat is determined  by twisting a single flat sheet to enclose a volume, much in the same way as the cut edges of a radius on a disk of paper can  be allowed to slid over themselves to form a cone.

The maximum curvature at any one point is singular. A right angle to the line of maximum curvature at any point is flat. And from this fundamental property of twisted planes issues the concept of  losing a volume enhancing curvature, present in almost all boat design. The exceptions being where multiples of twisted or bent planes are joined, as in sheet plywood and sheet aluminium boats.

I am suggesting losing this volume containing curve (bilge)  is offset by reducing the frictional surface over the whole wetted surface of the boat.
