Roger Hill 14m Power Catamaran - AYANA

Design Concept

The latest Roger Hill-designed vessel, the 14-metre power catamaran called “AYANA” has been designed to cruise from the Gold Coast back to Western Australia, with the intention of offering day charters cruising Rottnest, Margaret River and the Swan River.
“The fully-custom cat been built to survey and is at the top end of the spectrum for cost and compliance,” adds Roger, “and is complete with unique features befitting a luxurious liveaboard vessel.”

Construction

From briefing to completion, construction took just 13 months, and key to the build efficiency was the use of the pre-cut DuFLEX panel system from ATL Composites.

Nick Cossich, chief engineer at ATL, worked closely with Roger and Julianto comply with the DNV-GL Certification requirements and handled handled the plan approval process. Divinycell HM100 was the core specified for the DuFlex panels used for construction of the hull bottom, lower topsides and transom. Divinycell HM is capable of absorbing high dynamic impacts and slamming loads for fast marine hulls where higher toughness is required, while providing excellent resistance to denting.

Other DuFlex panels in AYANA were cored with Divinycell’s H80, an industry standard for high performance marine projects. All components for the build, from temporary framing to structural hull sections, bulkheads through to the interior fit-out for AYANA were digitised from design files and nested to optimise the number of panels required for the project that were with ATL’s proprietary Z-Joint for joining and subsequent quick assembly.

“DuFLEX is incredible for saving time and reducing weight onboard,” Julian Griffiths attests. “DuFlex offers builders a very high-quality panel and very precise accuracy, and for the client, an assurance of structural integrity.”

The interior fit-out on AYANA was also supplied as a CNC-routed Component Pack in FEATHERLIGHT FF1015X6 Marine Grade panels from ATL. Cored with 15mm Divinycell H60, a low density unique combination of polyuren and PVC core, the Featherlight panels will provide good thermal/acoustic insulation and will provide superior stiffness and ultra-light weight to increase overall performance.

KINETIX Laminating and WEST SYSTEM epoxy systems were used throughout the project to ensure high-performance structural properties and low maintenance in the years to come.

Roger agrees, stating: “Using the ATL Composites DuFlex panel system is a great way to build a boat particularly when it is embraced so well by this builder. Personally, I really appreciate the service and help that the team at ATL offers me as a designer. Their back-up and support are great.”

AYANA is a spacious three-cabin multihull conceived for day charter, with a massive, versatile cockpit for entertaining or angling, which flows into the large saloon, also decked out for socialising with dinette, galley, AV and large windows for panoramic views. The enclosed flybridge features the helm and an L-shaped lounge and dining table, while the aft deck is fitted with a davit for the vessel’s tender.
