Swath hull forms

SpletThe SWATH form was invented by Canadian Frederick G. Creed, who presented his idea in 1938, and was later awarded a British patent for it in 1946. The first full-scale SWATH vessel to be built and put into service was MV Duplus, [3] a diving support vessel built in the Netherlands in 1968.
