Converting Hard Chine Sailboats to True Round: Bezier Chine Design

By D L Schaffer

The purpose of this writing is to illustrate the practicality of changing a Double Hard Chine design to a True Round design for purely architectural pleasing motivations. To this end, I will be converting a double hard chine steel hull designed by myself many years ago into a true round version of itself. To do the conversion I will be using 'Bezier Chine Design and Construction'. A construction method developed by myself that enables builder to fabricate True Round metal hulls as easily as a Hard Chine hull. A full understanding of the building process can be found in my book 'True Round Metal Boat Building - Bezier Chine Design'. In this book the actual conversion process is not covered. A full understanding of the mechanics of the conversion can be found in my book 'True Round Metal Boat Design - Bezier Chine Design. The purpose of this book is to show the practically of converting a Double Hard Chine design to a True Round design between the Free-board and bottom hull section of a Chine design. Ultimately I will compare and comment on all aspects of the conversion by way of Visual characteristics, Hydrostatics, Coefficients, Stability, Resistance, Speed predictions, and a Race simulation between the original Hard chine design and the Bezier True Round Design. The process is so seamless that the builder can continue to use their original drawings to construct every aspect of the design, except the newly converted true round section between the free-board and bottom of the hull. In the end, the transition from Hard Chine to True Round is no more than an addendum or supplement to the original drawings.
