Design Concept
Aura, designed and built by Norman R. Wright and Sons in Brisbane. Engineered by ATL Composites. The 60-foot power boat was designed for private use and built for live aboard sports (game) fishing, with appropriate seakeeping, maneuverability and general handling capabilities. The vessel was configured to facilitate sports fishing; the main deck is fitted with a below floor scuppering system, a plumbed live bait tank located in the transom, and port and starboard desk hatched leading to removable fish/ice buckets. Aura can reach up to 35 knots plus, allowing for more time with lines in the water and less time traveling to your destination.

Construction
Engineered by ATL Composites, the hull bottom was infused with Kinetix R118 with H120 infusion hardener.  The hull core was 40mm Divinycell H130 IPN foam, which has a proven track record in marine applications in applications that are subject to slamming or impact loads, and reinforced with multiple layers of 800g E-fibreglass biaxial and quadraxials.

The hull topsides were strip planked using DuFLEX strip-planks with a 25mm Divinycell H130 foam core laminated with 800g E-fibreglass unidirectional on each side.   An additional layer of 800g quadraxial was applied to each side to complete the structure.

Pre-routed DuFLEX panels were supplied in kit form for applications throughout the boat including fitout and internal structural components:

– Accommodation Sole  –  20mm Divinycell H80 with layers of 1200g E-glass multiaxial reinforcements on each side.

– Saloon Sole  –  70mm ProBalsa end-grain balsa core with layers of 800g E-glass biaxial each side.

–  Bulkheads  – a combination of 25mm and 30mm Divinycell H130 cores with multiple layers of 800g E-glass multiaxual reinforcements on each side.

Specific reinforcements and taping were applied throughout the boat –  including 800g E-glass biaxial / 800g E-glass quadraxial / 1200g E-glass quadraxial / 1000g E-glass unidirectional / 600g E-glass double bias / 400g E-glass biaxial / 450g carbon unidirectional / 400g carbon double bias –  to meet design and engineering specifications.

As mentioned,  infusion processes were completed with KINETIX R118 with H120 infusion hardener,  and all hand lamination resin was completed with KINETIX R246TX resin, a room temperature curing, thixotropic laminating system,   with a combination of H126 Super Fast and  H160 Medium hardeners to meet specific cure schedules.
