iYacht unveils Hu'chu 55, a sustainable performance catamaran
iYacht GmbH has just unveiled the Hu'chu 55, a 55-foot performance catamaran that marks a turning point in sustainability and circular economy in boatbuilding. Designed in close collaboration with Daniel Roesner, actor, producer and environmental entrepreneur, this catamaran promises to revolutionize eco-responsible sailing.
"Hu" is an abbreviation of the place where Daniel Roesner grew up, the Hunsrück in Germany, a land where the production of natural materials such as wood, linen and hemp has a long and historic tradition. "Chu" refers to a place north of Malibu where the man discovered one of his passions, surfing. The name "Hu'chu" represents the earth and its natural materials in combination with the ocean.
An ambitious, sustainable project
The Hu'chu 55 is no ordinary project. Among the 200 projects managed by iYacht GmbH over the past two decades, this catamaran stands out for its innovative approach to sustainability. IYacht CEO Udo A. Hafner, underlines the importance of this project: "We've designed and developed a dozen multihulls in recent years, but the Hu'chu 55 represents a significant leap forward in terms of sustainability and circularity."
For this project, a multi-disciplinary team was assembled, comprising yacht designers, industrial designers, naval architects, structural engineers and project managers: more than 8 iYacht team members were involved. The designer and owner are currently in talks with several yards to assess their ability to build the boat. They are keen to find a yard with the most experience in aluminum construction.

Eco-responsible design and construction
The Hu'chu 55 is designed with recycled and recyclable materials. Roesner has produced an aluminum specially developed for the Hu'chu 55 in cooperation with a major aluminum manufacturer that consists of over 90% aluminum scrap without a single kilogram of primary metal. The scrap comes from discarded license plates, road signs, cosmetic cans, automotive and construction scrap, as well as shredded scrap from recycling and sorting plants. This considerably reduces the CO2 footprint to less than 2 kg CO2/kg of aluminium sheet.
In addition, the boat incorporates natural fibers, reclaimed wood and recycled cork, selected for their environmental contributions. The bare metal exterior gives the boat a rugged aesthetic befitting an exploration catamaran, while the interior is complemented by various shades of brown and black.

A versatile navigation program
Designed to meet Daniel Roesner's specific needs, the Hu'chu 55 is a robust multihull for adventure, film production and ocean research. The rig and sail system are designed for easy maneuverability from the helm and aft cockpit. Three stays with a self-tacking sail, overlapping genoa and code or gennaker offer versatility in adapting to different wind conditions. Daggerboards enhance upwind performance. To facilitate mainsail maneuvering, the mast has been positioned far aft. This design decision has consequently increased the surface area of the headsail.
The catamaran is suited to sailing in both high and low latitudes, typical of an Explorer dedicated to ocean research. The rudders and lower hulls have been reinforced to withstand ice encounters and possible collisions. The Hu'chu is also designed for grounding: rudders and propellers are protected by a pair of profiled keels that can support the weight of the boat once grounded.

Interior layout and on-board comfort
The interior of the Hu'chu 55 is designed for life aboard, because that's what the owner intends to do - live aboard and make films. It includes an area dedicated to film editing, dry storage to protect electronics and special equipment, and two garages for diving and sports equipment. A hydroponic (soil-free) garden even allows vegetables to be grown on board, ensuring food self-sufficiency.
Once on board, Roesner plans to produce ocean documentaries and monitor water quality.

Respect for the environment and technological innovation
The Hu'chu 55 incorporates electric motors for silent, vibration-free propulsion, powered by solar panels and a hydrogeneration system during sailing. Battery capacity is 100 kWh. The photovoltaic panels will generate electricity for all on-board needs: for growing vegetables, for the water desalination system and for all energy consumption, such as the assembly room where the owner will work.
Choices such as the absence of energy-hungry air conditioning and the use of insulated glass and optimized ventilation systems illustrate the project's commitment to sustainability.
An inspiring project for the future
Daniel Roesner hopes that Hu'chu 55 will serve as a platform for sustainable research and adventure, while inspiring other similar initiatives. "I hope the Hu'chu 55 will also be a source of inspiration for others" he declares. This catamaran embodies a respectful combination of nature and technology, proving that it is possible to sail while being more respectful of our planet.
