Described on his death as "the father of post-war offshore sailing racing",[1] he held most of the senior positions in British yachting and pioneered several innovations in the sport.
In 1945, after the end of the war, Illingworth was in Australia, organising repairs in Sydney for the British Pacific Fleet.
Myth of Malham was a 37-foot-6-inch (11.43 m) sloop built at Greenock, designed by Laurent Giles to Illingworth's specifications.
As described in Chichester's book Gipsy Moth Circles The World (Coward-McCann, Inc NY), she was an ill-mannered lady.
Illingworth believed that offshore racing could be conducted safely in boats which were much smaller, lighter and simpler than was the norm at the time.
