Archipelago Yachts, in collaboration with Chartwell Marine, has announced the successful completion of the design for its groundbreaking zero-carbon leisure vessel, the Archipelago zero.63. The project harnesses cutting-edge technology to set a new benchmark for sustainability in the leisure marine industry.

The Archipelago zero.63 features a parallel hybrid system that seamlessly combines the clean energy derived from a pair of methanol reformers and hydrogen fuel cells. This innovative propulsion system allows the vessel to cruise silently at speeds of 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 remarkable features of this vessel is its substantial 10,000-liter methanol tank, providing an expected range of around 2,500 nautical miles, making it a highly versatile and long-range option for adventure-seekers. The Archipelago zero.63, built from low-impact aluminum, can comfortably accommodate eight passengers in four luxurious cabins, all equipped with en suite facilities, ensuring a premium, yet eco-conscious cruising experience.

The Archipelago zero.63 is poised to make an impact as its unique combination of methanol as a zero-carbon fuel and advanced hydrogen technology brings a useful solution to the challenges of marine decarbonization. To ensure the safety and integrity of this pioneering vessel, extensive assessments were conducted in collaboration with Lloyd’s Register, assuring the highest standards in design and construction.

This project aligns with Innovate UK’s “Transport Vision 2050,” which aims to incorporate methanol as a viable marine fuel, targeting approximately 25% usage by 2050. Chartwell Marine’s success in securing an Innovate UK Smart Grant demonstrates its dedication to advancing sustainable marine technology.  

With the design phase now complete, Archipelago Yachts and Chartwell Marine are primed to build and unveil the Methanol Pathfinder UK, a one-of-a-kind demonstrator vessel that will showcase the potential of methanol as a marine fuel, leading the way towards a greener future for the marine industry.

The Methanol Pathfinder UK will serve as a platform for proof of concept, inspiring confidence among manufacturers and innovators in the marine sector. It promises to be cost-effective to build, making it an attractive proposition for banks and funders. Moreover, its hydrodynamic design, reminiscent of crew and fast ferry transport vessels, opens up opportunities for commercial exploitation and deployment worldwide.

Dr. Stephen Weatherley, founder and managing director of Archipelago Yachts, said: “Our vessel design uses methanol-to-hydrogen reforming technology to power a modern and attractive, silent, zero-carbon 63 leisure vessel. The yacht will be state of the art for zero-carbon technology, built from low-impact aluminum, 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, said: “Utilizing 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.”
