Dr. Sam Bradfield has passed away. He was an inspiration to me and helped me learn a lot about hydrofoil sailing design. He had a way of explaining hydrofoils in a simple straightforward way. Sam designed an improved version of the wand surface sensors that regulate hydrofoil altitude. His basic system was copied and improved by John Illett and other Moth designers. After one summer where he used a trimaran platform of mine to test concepts for the 40′ Skat, I designed a 56″ radio controlled foiler, the F3, and a 16′ monofoiler based on what I learned from Dr. Sam. He was an innovator, teacher and a great man. – Anarchist Doug. Thread here.
