In an ambitious step towards sustainable marine travel, German actor and environmental entrepreneur Daniel Roesner has teamed up with yacht design and engineering studio iYacht to create a 55-ft solar-electric catamaran named Hu’chu 55. This eco-friendly vessel, built with circularity in mind, aims to set new standards in yacht construction by utilizing scrap metal, reclaimed wood, and recycled cork.
Circular design and sustainable materials
The Hu’chu 55 catamaran represents a significant leap in sustainable yacht design. Roesner and iYacht have meticulously planned the use of environmentally friendly materials to minimize the vessel’s ecological footprint.
The catamaran’s primary structure will be crafted from an innovative aluminum alloy, composed of over 90% recycled scrap metal. This unique blend is sourced from various discarded items, including license plates, road signs, cosmetic cans, and automotive and construction scraps. Remarkably, this recycled aluminum boasts just one-eighth of the carbon footprint compared to standard market alternatives.
Beyond the metal framework, the Hu’chu 55 will incorporate natural fibers, reclaimed wood, and recycled cork. These materials not only reduce environmental impact but also enhance the vessel’s aesthetic and functional qualities, aligning with Roesner’s vision of a truly sustainable catamaran.
Efficient sailing and renewable energy
Designed to operate primarily under sail, the Hu’chu 55 features an advanced rig and sail system for optimal performance and ease of handling. The catamaran is equipped with three forestays, including a self-tacking staysail, an overlapping genoa jib, and a gennaker, all supported by optimized daggerboards. The mast’s strategic positioning towards the aft simplifies mainsail management, ensuring efficient and manageable sailing.

Complementing its sail power, the Hu’chu 55 is equipped with two electric motors and a 100-kWh battery pack. These batteries can be passively charged through the spinning propellers as the yacht sails, as well as via solar panels installed on the vessel. This dual charging system ensures a steady supply of renewable energy to meet the yacht’s power needs, including water treatment and onboard electronics, such as those in the film editing room.
Living and working at sea
Roesner’s plans for the Hu’chu 55 extend beyond leisure; he intends to live and work on the catamaran, producing documentaries and conducting ocean research. To support this lifestyle, iYacht has designed the vessel to navigate both high and low latitude destinations, incorporating features that enhance self-sufficiency and adaptability.

Vertical hydroponic gardens are integrated amidships, providing fresh produce regardless of location. The yacht also includes dry storage for electronic equipment and two garages to house diving and sports gear. These features ensure that Roesner can maintain a sustainable, self-reliant lifestyle while pursuing his passion for environmental documentation and ocean exploration.
Moving from concept to reality
With the design phase complete, Roesner is actively seeking partners, sponsors, and investors to bring the Hu’chu 55 concept to life. Additionally, he is looking for shipyards experienced in aluminum construction to build the catamaran. This collaborative approach aims to pool resources and expertise, ensuring that the Hu’chu 55 not only meets its ambitious sustainability goals but also sets a precedent for future yacht designs.
