19.9m Long Range CruiserDesign Concept Norman R Wright & Sons, Bulimba, Queensland, were commissioned to design and build a traditional power launch that could perform efficiently, on both ocean and coastal passages, and provide safety and comfort for the owners. QUANDAMOOKA's displacement hull is typically narrow for her length, with a deep keel to protect the propellers. Combined with a fine entry, Quandamooka achieves good fuel economy with a relatively high maximum hull speed. Tank test results proved the design to be very efficient, and in real life conditions the launch is easily driven with excellent ride comfort. Construction Hull construction is cored composite, strip planked in Hoop pine and laminated with multaxial E-fibreglass and KINETIX high performance R246TX laminating resin with H160 medium hardener. Extended working times make this system ideal for large laminating jobs, and the thixotropic nature of the R246TX is ideal for avoiding drainage when working with heavier reinforcements. The remainder of the vessel is marine plywood, with all external surfaces sheathed in E-fibreglass and laminated with epoxy to ensure excellent moisture exclusion and low-maintenance longevity. WEST SYSTEM brand epoxy products and Techniglue-CA adhesives were used extensively in the construction of Quandamooka.
