Dudley Dix

Dudley Dix is a yacht designer, of South African origin, now based in Virginia Beach, US. He graduated from the Westlawn School of Yacht Design. He is notable for having developed the "radius chine plywood" method as a basis for boat construction. Dix won the 1979 Cruising World Design Competition.
Dix has designed yachts of many types employing a variety of materials for the hulls. His building methods include cold moulding and radius chine plywood. The radius chine plywood method was developed by Dix himself, and many of his designs use this procedure. The radius chine plywood method enables fast, cheap construction of relatively lightweight vessels. Dix is particularly concerned that his designs are fully seaworthy.
Dix has built many of his own designs for his personal use, including the Didi 38 "Black Cat" which he sailed from 1995 until 2000.
One of Dix's larger designs is the 55' DH550 ocean-going cruising catamaran, such as "Friends Forever".
