Robert D. Hayward (October 28, 1927 - September 10, 1961) was a Canadian powerboat racer who was a three-time winner of the Harmsworth Cup as the pilot of Miss Supertest III. From Embro, Ontario, Hayward was raised on his family's chicken farm and joined the Supertest racing team as a mechanic in 1957. Piloting Miss Supertest III, Hayward won the Harmsworth Cup in 1959, 1960, and 1961. A month after winning his third Harmsworth Cup, Hayward was killed while racing Miss Supertest II at the Silver Cup regatta on the Detroit River. The boat flipped over at 175 mph, breaking Hayward's neck. He was 33 years old. After his death, the Supertest team retired from racing.
