DescriptionPlan of BALLYHOO construction, trailing edge of rudder. HistoryTank testing yacht designs has been an important tool for a yacht designer to assess changes in a yacht's proportions and their effects on its potential importance. For many years only smaller scale models could be tested because of the small size tanks available. Lexcen and his design team which included draughtsman and model builder Dennis Philips built and tested a small number of 1:13.3 scale models for the design of the yacht SOUTHERN CROSS in 1974 with the series number 71xx and 72xx. They were run in the small tank at the University of Sydney Engineering Department.
