Archipelago Yachts and long-term collaborators Chartwell Marine have completed the design for the zero-carbon leisure vessel, the Archipelago zero.63.

This project harnesses cutting-edge technology, which the firms both say will set a new benchmark for sustainability in the leisure marine industry.

The Archipelago zero.63 has a ‘parallel hybrid system’, combining the clean energy derived from a pair of methanol reformers and hydrogen fuel cells. This propulsion system allows the vessel to cruise silently at up to 10 knots. For high-speed performance, the design includes a direct-injection methanol engine, enabling the boat to reach a top speed of 22 knots.

One of the most innovative features of this vessel is its substantial 10,000-litre methanol tank, providing an expected range of around 2,500 nautical miles.

The Archipelago zero.63, built from low-impact aluminium, can accommodate eight passengers in four luxurious cabins, all equipped with ensuite facilities.

Archipelago says the zero.63 is poised to make a significant impact as its unique combination of methanol as a zero-carbon fuel and hydrogen technology is being explored as a solution to the challenges of marine decarbonisation.

To ensure the safety and integrity of this pioneering vessel, extensive assessments were conducted in collaboration with Lloyd’s Register.

With the design phase now complete, Archipelago Yachts and Chartwell Marine say they are primed to build and unveil the Methanol Pathfinder UK. This one-of-a-kind demonstrator vessel will showcase the potential of methanol as a marine fuel.

The Methanol Pathfinder UK will serve as a platform for proof of concept, inspiring confidence among manufacturers and innovators in the marine sector. Designers say its hydrodynamic design, reminiscent of crew and fast ferry transport vessels, opens up opportunities for commercial exploitation and deployment worldwide.

“Our vessel design uses methanol-to-hydrogen reforming technology to power a modern and attractive, silent, zero-carbon 63’’ leisure vessel,” says Dr Stephen Weatherley, founder and managing director of Archipelago Yachts.

“The yacht will be state of the art for zero-carbon technology, built from low-impact aluminium, using recycled materials wherever possible. There are plenty of electric leisure vessels in the market which can travel short distances quickly or long distances slowly, but none can perform in high sea states, cross oceans, and be zero-carbon all at the same time.”

Andy Page, managing director of Chartwell Marine, adds: “Utilising Methanol as a feedstock for onboard propulsion and hotel loads is a real alternative to using diesel. The system developed for the zero.63 is simple, robust and manageable in terms of weight and geometry without significant compromise to the vessel aesthetic, interior or function. Using a parallel-hybrid propulsion system allows owners to operate the yacht silently using electric propulsion, as well as methanol combustion for high-speed operation.”

In separate news, Archipelago Expedition Yachts has recently sold its first Archipelago 40, as reported by MIN in October 2023.

The explorer vessel, also designed by Chartwell Marine, offers customisable cabin layouts and adaptability for diverse commercial and semi-commercial purposes. The company says its aluminium construction offers exceptional stability, resulting in a smoother voyage and increased living space.
