True Round Metal Boat Building
(Made Easy)


Metal Boat Building

Bezier Curve Design is for "Builders" of Steel and Aluminum Boats. It is for amateurs and professionals alike. It is about building "True Round" steel and aluminum hulls. It is a design and construction methods simipfling the construction of "True Round" Hulls.

How to simplify TRUE ROUND metal construction?

The first step towards simplifying construction of rounded metal hulls is a popular building method know as "Radius Chine". This method places a large single radius (arc of a circle) along and between two developable (flat) surfaces. At it's best "Radius Chine" only imitates a true round hull. While "Radius Chine" construction is a good first step towards rounded metal hull forms it is not a "True Round" hull form.

By it's own nature, "Radius Chine" severely limits hull shape to it's own end. By necessity the method places most of the curved section of the hull below the waterline, making it's hulls appear slab sided. "Radius Chine" does not produce the hull we all know, love, and want in our true round designs.

"Bezier Curve" takes the basic concept of "Radius Chine" to the next level. An example of this is shown by the construction the the Bezier 12.5 - A true round tumblehome design.

Bezier Curve Chine:

"One Of" Metal boat builders, like us, who have been limited to hard chine designs can now build true round metal hull using the "Bezier Curve" chine construction method. This innovative construction method enable you to build a true round design as easily as a hard chine design.

Bezier Curve Design and Construction does not use Line Heating, English Wheels, special tooling, fixtures, exotic methods, or Explosive and Hydraulic forming. The beauty of Bezier Curve is that I can actually teach you how to use it within metalsailboats.com. The method is consistent and predictable. There is nothing vague about the method both written and visual. You can see the process thoroughly by following the building of the "Bezier 12.5". Chose a topic on the "Right Toolbar".

If you think you have the skills to build a hard or radius chine hull, then you have the skills to build a true round hull using the "Bezier Curve" method.

Metal sailboats. com does not just have a dialogue about obscure methods to build a true round hull. Metalsailboats.com details true round metal boat building methods and, provides all the necessary plans and Cad/Cam files to build it.

Bezier Chine in a nutshell:

  • Bezeir Curve does away with vague and obscure techniques to achieve a true round hulls.

  • Hull panels are shaped using a cold forming "Press Break" process. The method is simple, consistent, and predictable.

  • Bezier Curve Design produces full size flat patterns of the hulls three dimensional surface. Information such as bend angle, forming line, and reference dimensions needed to form the flat patterns to it's original three dimensional shape are also provided with the each patterns.

  • The curved sections of this hull fit together easily, with minimal adjustment onto the framework.

  • The pre-engineered design and fabrication method enables an average person to build a true round bottom hull using the same skills as required in hard chine construction. There are no vague and obscure methods doable only by professional boat builders.

  • The result is the unmistakable beauty of a round hull - the uninterrupted graceful line curving to meet the water.
