Among the 200 projects managed by iYacht GmbH over the past two decades, the ALUCAT C55 is without a doubt one of the most sustainable and compelling challenges undertaken so far. iYacht’s CEO, Udo A. Hafner stated, ‘We have designed and engineered a dozen multihulls in recent years, but the Alucat C55 represents a significant leap forward in terms of sustainability and circularity. Daniel had a very ambitious vision, and we guided him in turning it into a feasible project”. The brief was to create a sustainable catamaran designed with circularity in mind: a robust multihull on which the owner can live adventure, produce films, and conduct ocean research.


Alucat C55´s owner, Daniel Roesner, renowned as an actor, film producer, and environmental entrepreneur, is above all an ocean lover. He expressed, “I am not an engineer or scientist, but someone who truly fell in love with the water and the planet he lives on. The design and engineering office iYacht acted as a filter for my imagination. While some of my ideas were challenged technically, for most of them iYacht confirmed the feasibility and even enabled me to go one step further’. The team at iYacht’s design offices in Hamburg and Kiel incorporated Daniel’s wishes and concepts, giving birth to the Alucat  C55.
