Arksen 85 Explorer Yacht made of VIA Maris Njørdal

Arksen has chosen Speira marine-grade aluminium for its new explorer yachts. Speira supplied low-carbon rolled aluminium of the material type VIA Maris Njørdal and supported with many years of expertise in the application of aluminium in shipbuilding.

Builder: Arksen Ltd

Year: 2023

Design and naval architecture: Humphreys Yacht Design

Structural engineering: Chartwell Marine

Shipyard: Wight Shipyard UK

Hull and superstructure: Aluminium (Materialtyp VIA Maris Njørdal)

Explorer yacht made of aluminium with high recycled content

“Njørdal is a really exciting product for Arksen, not only does it have higher mechanical properties than many grades in marine aluminium, but also has a higher recycled content, which is a really key thing for Arksen in our sustainability pathway,” says Jim Mair, Technical Director at Arksen.

The aluminium sheets used for the hull and superstructure were made from a combination of recycled aluminium and process scrap in combination with primary aluminium. The recycled content of the sheets is over 70 percent. Once it comes to the disposal of the aluminium yacht, the selection of materials is particularly important. Aluminium is infinitely recyclable and remains a valuable material even when the yacht has reached the end of its service life.


Intelligent yacht building for high range and low emissions

At an early planning stage, Speira was able to provide advice on how to optimize the aluminium construction and design the vessel in a recycling-friendly way. The intelligent design of the hull results in lower fuel consumption, which translates into lower operating costs, high range and lower emissions.

“Projects like this from Arksen are a step in the right direction for the potential of recycling materials in the marine sector. For this project we have supplied Njørdal, an alloy which is stronger and more durable than other aluminium alloys. This also permits an innovative light-weight design, which greatly reduces energy consumption,” says Speira's UK sales manager David Goddard.


Arksen sets new benchmark with the aluminium explorer yacht

The maritime innovation, technology and adventure company is introducing its first eco-conscious explorer vessel, the Model 85, with the ambition of developing a fleet of more sustainable yachts that can also be used for marine research and conservation. The development of the hybrid-powered Arksen 85 focused on low maintenance, efficiency and sustainability throughout its life cycle.

The corrosion resistance and robustness of the aluminium make the yacht one of the safest and best performing vessels in its class. The blank, unpainted surface gives the explorer yacht a unique look and ensures that maintenance is kept to a minimum. Owners can explore the globe with confidence and independence. Wight Shipyard, which specializes in aluminium, was commissioned to build the Arksen 85. In spring 2023, the innovative aluminium yacht successfully completed her sea trials on the south coast of the UK. In the coming years, the yacht will undertake research and conservation cruises and make appearances at various marine trade shows.
