Ultimate Catamarans

Ultimate Catamarans GmbH, based in Bonn, Germany, specializes in the design and construction of premium aluminum superyacht catamarans. The company was founded by Ralph Wuttke and operates with a team of industry specialists, including naval architect Hans Konings and designer Laura Pomponi of Luxury Projects.

The company’s Spaceline series includes models ranging from 88 to 180 feet. These yachts are engineered with aluminum hulls and superstructures, providing significantly more interior and exterior volume than monohulls of similar length. For example, the Spaceline 88 model features over 800 square meters of total space, including guest cabins located entirely on the main deck.

Production is centered at the Iskra shipyard in Šibenik, Croatia, a facility with an extensive background in aluminum shipbuilding. This partnership utilizes the shipyard’s specialized workshops and technical infrastructure to ensure high standards of quality and precision engineering for each build.

The company integrates advanced technical systems into its designs, including hybrid propulsion and solar panel arrays. These features allow for reduced fuel consumption and noise-free operation at anchor. Additionally, every yacht is delivered with integrated management software from IDEA Data Solutions to facilitate technical maintenance and safety management.

The yachts are built to order, allowing for extensive customization of interior and exterior layouts. Design elements such as 2.2-meter ceiling heights and the placement of generator exhausts on the rooftop are standard across the series to enhance guest comfort and functionality.
