A Yacht Mast

The mast, fitted to the Safari catamaran, is 13 m long (from above the boom to the masthead). The chord length (from the leading edge to the trailing edge) at the base is 760 mm and tapers to 240 mm at the masthead.

Some applications do not require a pattern etch but require an overall etch to thin the material or reduce weight in racing cars or even to taper a tall structure such as a yacht mast. These techniques are often applied to aluminum and titanium alloys, stainless steels, and even superalloys such as Rene 41 (Bellows 1977 Dini 1984).
