Dave Miller was only a teenager when he began competing in the Junior North American Championships, and notched his first victory in the tournament in 1960. He followed that with a win at the Junior World Championships that year and, as a student at the University of British Columbia, was eventually selected to represent Canada at the 1964 Summer Olympics in the Star Class. He placed seventh in the tournament, with William West, and then switched to the Dragon Class, missing the podium by just one spot, alongside Timothy Irwin and Steve Tupper, at the 1968 edition. In 1969, now with Paul Côté and John Ekels, he began to compete in the Soling Class and, two years later, the trio captured a bronze medal at the 1972 Summer Olympics, having earned the right to represent Canada by winning all eight races at the national trials. Miller retired from active competition after his team won the 1973 North American Championships and founded North Sails in 1974, having previously worked in his father and uncle’s sail-making business. He retired in 2010, passing the reins of the company to fellow Olympic medalist Ross MacDonald. Miller was inducted, along with the other members of his bronze medal-winning team, into the British Columbia Sports Hall of Fame in 1989.
