Lock Crowther (c. 1940?–1993; first name by birth Lachlan[1]) was an Australian multihull sailboat designer. He grew up in Bairnsdale in the East Gippsland region of Victoria.[1] Though his first name was Lachlan by birth, he insisted on being called Lock or Lockie.[1]

Career

Lock and his family[1] built his first boat, a trimaran called Bunyip, in 1959 while he was still a teenager. In 1960 he raced in the Easter regatta at Paynesville, Victoria, Australia, and won against a field of 300 boats. This initial success inspired others to build similar boats. Crowther then studied electrical engineering in Melbourne[1] and in the early 1960s became involved in multihull design and the Amateur Yacht Research Society.[2] In 1962 Trio was built based upon his designs.[1][3]

Crowther's next design was the Kraken 25, garnering some recognition.[2]

Later, Lockie decided to give up his day job in Melbourne and move to Sydney to design multihulls full-time.[1]

In 1969, a Kraken 40 won the New York to Bermuda race with him aboard.[2]

Crowther's first offshore racing trimaran, Bandersnatch, won the Sydney to Hobart multihull race in 1996.[2]

Legacy

During Crowther's career, over 2500 of his designs were built.[2] A notable design was the trimaran Spirit of America, an early user of GRP-foam sandwich construction featuring composite beams with unidirectional fibres and turned-down ends. Crowther also developed 'bulbous bows' to reduce pitching, and thus increase speed when sailing upwind in a swell.

After Crowther's death in 1993, Crowther Designs was run by his son, Brett.[2] Based in northern Sydney, it merged with Incat Designs - Sydney in 2005[4] to form Incat Crowther.[5] Some Crowther designs are now offered[6] through Melbourne-based Bloomfield Innovation, run by a former associate.
