DescriptionPlan that pictures a general assembly of a feathering propeller with cross sections, elevations, specifications for component parts and machining instructions.HistoryProfessor 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.
