DescriptionThe hull of the 18 foot skiff COLORBOND designed by Scott Jutson. Featuring a composite sandwich construction outer skin of nomex paper honeycomb core material, baked and cured with a carbon fibre cloth and inscribed COLORBOND in red along the hull.HistoryCOLORBOND was developed by two aeronautical engineers and a naval architect on behalf of BHP. Some research and development was undertaken in the United States with hydrodynamic computer simulation and stress analysis being completed in Australia. The high-tech hull has a composite sandwich construction outer skin of Nomex paper honeycomb core material.The hull was then baked and cured with a carbon fibre cloth. A carbon fibre frame gives the hull rigidity and strength. The skiff has carbon fibre wings, alloy mast and boom, a selection of Kevlar/Mylar sails, and a lightweight Dacron spinnaker. The retractable spinnaker pole is made of Nomex and carbon fibre. This construction technique further reduced hull weight without sacrificing overall strength. This method of construction, like the boat's design, relies on technology that has evolved in the aeronautical industry. The thing that has become obvious about 18-footers is that their development is only Iimited by the imaginations of the men who design, saiI and buiId what became the fastest mono huIled class in the world. SignificanceCOLORBOND represents the ultimate 18 foot skiff developmenrt up to the 1980's and completes the Museum's story of the development of 18-foot skiffs from BRITANNIA of the 1910s, TAIPAN of the 1950s and KB of the 1970s .
