’Bezier Chine’ is a design and construction method to fabricate true round metal hulls. It is a true round form in every respect, just like a fiberglass designed hull. It is easier to build and requires far less metal working skill and equipment over building a true round hull by traditional means. The entire hull surface is pre-engineered. All plating fit seamlessly to a specified location on the hull framework.
Single Surface Bezier Design:
The Single surface ‘True Round’ Steel or Aluminum Bezier hull, shown below could have also been designed for Fiberglass construction. Any hull designed for fiberglass construction can be built in steel or aluminum using ‘Bezier Chine Design and Construction’.
Double Surface Bezier Design:
In a Double surface design, the upper warped surface runs from the sheer-line, around the turn of the bilge to a theoretical chine line. The bottom Developable surface then picks up at the theoretical chine line to the center line of the hull.
The theoretical Chine Line that separates the two surfaces are visible in the hulls ‘Lines’ drawings. However, in the finished hull the Chine Line blends the two distinct surfaces into one by flowing tangent and seamlessly into one single perceived surface.
Triple Surface Bezier Designs:
‘Radius Chine’ is a triple surface hull design method that places a ‘Single Constant Radius’ between two developable surfaces along the entire length of the hull. The configuration was developed somewhere back in the 1980’s to simplify True Round hull construction.
Technology however has advanced where the ‘Single Constant Radius’ of a ‘Radius Chine’ design could be replaced by a ‘Bezier’ Free- formed True Round Surface, adding value by overriding the restrictions imposed by the ‘Radius Chine’ design method itself.
