True Round
Metal Boat Building
-  By Way Of  -

Approximate Development


The development of 'Bezier Design and Construction' is a result of my career in Architectural Metal Fabrication, CNC Programming, Sheetmetal pattern Development, and my studies at the 'Westlawn Institute of Marine Technology.

The metal True Round boat Building method that I am about to introduce, 'Bezier  Design and Construction', was developed entirely by the author.  It is a  is a high-tech computer design method that blends well with the proven time-honored sheet-metal fabrication layout method know as 'Approximate Development', and is the backbone of 'Bezier Design and Construction'.  There will be No Artistic, Vague, or Obscure  True Round metal Shell Plating methods addressed here.

On the Right Hand Column are other aspects of 'True Round Metal Boat Design and Construction' that you may find Interesting:

A simulated race (via VPP software) between a classic Day-sailor designed to be constructed in both Steel and Aluminum.

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?

The Layout and fabricate of custom Hatches, Port Lights, and more.

The advances in the 'English Wheeling' method for forming True Round Shell Plating.




Prototype Build

(The Bezier 12.5)

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.
