'Metal Fabrication' is the creation of metal structures by cutting and bending sheet-metal, than assembling those formed components into a pre-determined product.

‘Applied Metal Boatbuilding Methods’ – ‘Sheetmetal Pattern Development’ picks up after the hull and deck of a boat is constructed. Devoid of all features or a 'Bare Hull'. It begins another phase of the build with the fabrication of integrals such as but not limited to: Coamings, Hatches, Window Ports, Companionways, and Tanks. Some builder may ever want to fabricate there own mast and booms.

Fabrication of these components by the builder is another major economic advantage of building in steel or aluminum. Components such as these can be fabricated for nickels and dimes on the dollar over purchased manufactured versions of the product.

Custom fabricated steel components are also more in keeping with the hulls construction material ensuing a harmonious steel design that is not attainable using components designed for another construction material.

Layout and fabrication of these type of components are determined by well established empirical formulas known as ‘Bend Allowance’ and ‘Bend Deduction’. These formulas are in universal use throughout the metal fabrication industry.

‘Applied Metal Boatbuilding Methods’ – ‘Sheetmetal Pattern Development’ is a Metal Fabricators course in ‘Precision Sheet Metal Layout’. Teaching the theory, principles and application of these well established Sheetmetal layout formulas to calculate the cut sizes, locations of bend lines and interior features demonstrated through the fabrication of marine components typical to steel and aluminum pleasure craft.

It is a complete guide to all persons in the metal fabrication industry be they Precision Metal Fabricators or ‘One Of’ Metal Boat Builders. ‘Applied Metal Boatbuilding Methods’ – ‘Sheetmetal Pattern Development’ is basic to rounding out your metalworking layout skills.
