Bunyip 20
Bunyip 20 was a day racing trimaran sailboat designed and built by Lock Crowther and his family in 1959, while he was still a teenager. It was named after the Bunyip, an Australian mythical creature.
In 1960 Crowther raced the first boat at the Easter regatta at Paynesville, Victoria, Australia, and won against a field of 300 boats. This initial success inspired others to build similar boats, and began his career.
