True Round
Metal Boat Building
- By Way Of -
Approximate Development
The current 'Go to' methods for forming compound curved shell plating for steel and aluminum fabricated boat hulls are: 'Line Heating' for steel and 'English Wheeling' for aluminum. The down side is that both methods require highly skilled Craftsmen using very specialized techniques.
'Line Heating' only requires a minimal investment in equipment, while 'English Wheeling' requires a significant investment in equipment.
If you have the above skill and equipment I am a advocate of both 'Line Heating' or 'English Wheeling' as the method of first choice to form the shell plating for a True Round design.
However there is an 'Alternative Way' to form the shell plating for a True Round steel or aluminum hull that does not require the hands-on-skills or equipment required by 'Line Heating' and 'English Wheeling'.
The Alternative:
The True Round steel and aluminum Boat-building method that I am about to introduce, 'Bezier Design and Construction', was developed entirely by the author, and is the result of his career in Architectural Metal Fabrication, CNC Programming, Sheetmetal pattern Development, and his studies at the 'Westlawn Institute of Marine Technology'.
'Bezier Design and Construction' combines the traditional hand layout method of 'Approximate Development' with today Surface design Three-dimensional software where the compound surface can be unroll onto a single plane, than formed back to their intended three-dimensional shape by a cold-forming press-brake process.

The Prototype & Proof of Concept Build
If you have the metal-working skills to built a Hard Chine steel or aluminum hull design, than you have the ability to build the prototype and proof of concept Build shown below.
If the below curvy classic aluminum design can be built using 'Approximate Development', then any other true round hull form would certainly be a breeze.
Click on the below link (Hull Components) to see a preview of the Transverse Frames, Longintudinal Frames, and Shell Plate fabrication or (Building the Hull) for an overview of how the Hull is fabricated.

A simulated race, (via VPP software), between a Double hard chine hull and Her redesigned version to a True round hull form. (Note: This is not just a race between one person's steel Hard Chine Boat with another person's steel True Round boat, since the True Round Hull is a clone of the Double Hard Chine hull.) The result of the race will shine light on the long ask question. Which type of hull is faster, a true round hull or a Double Hard Chined hull? |
