Design essay for a hard-chine hull, idea: Ambrose Johnson, designer: Sébastien Schmidt. Basis: hull of SUI-201 Marie-Françoise XIV, possible material: plywood/aluminum. Advantage: low-cost construction method, very little wetted surface difference compared to a "traditional" design.
Two models (SUI-201 & hard-chine project) were tank tested at the engineering School of Geneva for comparison.
