The plan contains the arrangement of rudder, shaft and skeg; chords of rudder, half section outboard rudder bearings, and the arrangement of attachment of skeg to hull.HistoryThe first Wombat 42 yacht built, BOOMERANG VII, came second second in her class and overall in its first Sydney to Hobart race in 1969.
Professor Joubert was a highly respected engineer and lecturer and was a consultant for a number of private and government engineering projects. He had a sailing background and was a close friend of naval architect Alan Payne.
Professor Joubert's involvement in yacht design fulfilled a desire to be involved in this aspect of engineering without making it a full time occupation. He produced a small number of production designs that reflected his objectives of creating a strong, seaworthy yacht for racing and cruising. He also worked on the design of fast catamarans for racing and setting speed records, this is a specialised and niche area of yacht design, but an area where Australia has demonstrated extraordinary success in the past through other designers and builders who were contempories of Professor Joubert.
SignificanceThe plans of the Wombat class by Professor Peter Joubert, represent the design for a lighter displacement racing vessel built in fibreglass as a production yacht.
