Leading-edge technology is employed wherever this is proven cost-effective and ac improvements in hull efficiency to provide an optimum balance between passenger loading conditions and manoeuvrability. Austal's committed to implementing research and development initiatives that will shipbuilding industry. To support the production of the diverse portfolio of vessels, Austal is able to dr covering all facets of design including naval architecture, marine and mechanical e interior design and drafting.

Data is transferred electronically from the very start of the design process (hull sur models used for resistance and hydrostatic calculations into structural analysis (fin definition of nesting arrangement prior to cutting thereby preserving accuracy in d Austal pioneered the use of a bulbous-bow, rounded-bilge hull catamaran form dev (CFD) and extensive model testing to such an extent that it has been described by providing the best sea-keeping and lowest resistance in the catamaran market. Trimaran Technology Perhaps the single greatest technological advancement in Austal 's history is the de effectively decouples vessel length from capacity and permits the marriage of a co hull form that offers superior seakeeping in a range of conditions. The trimaran has been the subject of intensive tank test investigations into the mo acceleration data obtained from these tests is used, in conjunction with Austal's sim accurate predictions of the vessel's performance in any given sea area and operati These predictions provide an operator with information about how the vessel will p and passenger comfort. Predictions of roll angle, lateral acceleration and motion si The tank testing and simulation conducted shows, in a wide range of wave conditio catamarans and monohulls due to its ability to provide low transverse and vertical slender main hull of the trimaran is much longer and more slender than the hull of combined hulls of a catamaran. Therefore vertical motions are reduced. In addition trimaran also resulting in smaller vertical motions. The significantly lower metacentric height of a trimaran, which actually compares f monohull, produces lower roll accelerations, also reducing motion sickness.
