ATL and Diab composites used in Barcoo Drift

Optimised for fishing, the 14 m long vessel Barcoo Drift was designed by Roger Hill Yacht Design, New Zealand, and built by Julian Griffiths and his team in Noosa Marine, Australia, using sandwich core composite materials from ATL Composites in co-operation with Diab.

ATL Composites manufactures advanced composite materials, epoxy laminating and adhesive systems for the boatbuilding market in New Zealand and Australia. A leading supplier for the high-performance yachting market, ATL Composites also provides other industries with sandwich core composite materials, such as road and rail transportation, as well as industrial and architectural applications.

ATL has a long-standing relationship with the Diab Group as distributor for the company’s product range and processing cores with the various Diab finishing options and kitting services for the Australian market.

Fisherman’s dream

The owners of the vessel are fond of sports fishing and commissioned the design of a boat where the back and cockpit are specially designed to accommodate their preferred hobby. The power catamaran was constructed using a combination of DuFLEX Composite Panels with Diab’s Divinycell H80 and HM100 structural foam cores.

Some panels were laminated with unidirectional laminates, so they could be strip-planked to conform to the more compound sections of the outer topsides and wing-deck areas. “Built in just a year, Barcoo Drift is comfortable and stylish, but also strong and practical. It is the perfect vessel for all kinds of cruising and fishing adventures on the North Queensland coastline,” said Diab team.

Robust but light

To provide extra strength while keeping the vessel light, Divinycell HM100 was engineered into the hull bottoms and lower topsides. This way the boat can absorb high dynamic impacts and slamming loads without adding weight to the construction. All other structural sections including bulkheads, hull soles, cabin sides, side decks, etc. were supplied as CNC-routed DuFLEX Component Packs cored with Divinycell H80 in a variety of thicknesses and e-fibreglass reinforcements to meet design and engineering requirements.

“Providing excellent mechanical properties and low weight, Divinycell H is an all-purpose grade with a proven track record in virtually every application area where sandwich composites are employed, including the marine, transport, wind energy and civil engineering industries,” the manufacturer explains.

The interior fit-out was supplied as a CNC-routed Component Pack in Featherlight FF1015X6 Marine Grade panels from ATL Composites. The ultra-light panels, cored with 15mm Divinycell H60, a low density IPN foam, are designed to provide good thermal/acoustic insulation and superior stiffness to increase overall performance.

DuFLEX System

The Diab core range provides options to produce an optimum end product in terms of materials properties, sustainability and cost to meet specific applications. With the proven track record in marine applications, DuFLEX Composite Panels are manufactured with Diab’s Pro-Balsa or Divinycell Structural foam cores and laminated with a proprietary epoxy resin reinforced with multi-axial e-fibreglass or carbon fibre skins.

The DuFLEX Composite Component Packs are generated from electronic design files and state-of-the-art CNC machinery. “Stringent quality control systems ensure every job is made to designer’s specifications and customers are ensured of consistent part quality and higher production rates,” the company says.
