Australia’s largest luxury boat builder, Riviera, has taken another major technology step with the infusion of the hull on its new 5800 Sport Yacht – the largest such infusion project ever undertaken by Riviera.
by Denby Browning
The 5800 Sport Yacht is scheduled for release at the Sanctuary Cove International Boat Show in May next year.
Riviera CEO John Anderson said: 'The 5800 Sport Yacht our largest infusion project. We first adopted this leading edge technology on our very successful 4400 Sport Yacht last year. The 4400SY was named Boat of the Year for 2008.'
Mr Anderson said the benefits of infusion included a lighter weight hull that is very strong, with an exact glass-to-resin ratio and consistent thickness throughout.
Jim Logan, Lamination Manager at Riviera, said: 'The process is environmentally friendly and very comfortable for our staff. Basically, following the application of gel coat and a vinyl ester barrier coat, the layers of fibreglass and core are laid on the hull mould; then a plastic ‘infusion film’ is laid on top and sealed. The air is extracted through vacuum lines connected through the infusion film. Catalysed resin is then drawn into the laminate by the vacuum and infused evenly throughout the sealed area.
'The resin infusion process takes about two hours. We leave the hull to cure then begin installing the longitudinal and transverse stringers into the hull.'
Riviera has already received orders for six of the four-cabin 5800 Sport Yachts which include three of the revolutionary Volvo Penta IPS drive units.
