Oceanco has launched the 111-meter diesel-electric yacht Leviathan, previously known as Project Y722, at its facility in the Netherlands. The vessel features naval architecture by Oceanco and Lateral Naval Architects, exterior design by Oceanco, and interiors by Mark Berryman Design.Commissioned by an experienced owner, Leviathan was developed with a focus on operational efficiency and crew wellbeing. According to Oceanco, crew members were involved in the design process to provide practical input.

These choices are intended to reduce routine upkeep and allow crew to focus on guest services and operational tasks.The project involved collaboration between the owner, technical representatives from YTMC, and management company Y.CO. More than 2,000 people contributed to the build, and their names are engraved on a glass panel in the main staircase.Leviathan is designed to accommodate a variety of uses, including hospitality and scientific work. She has a beam of 17.8 metres and is scheduled to begin sea trials in the coming weeks. Further details on her capabilities are expected to be released later.Credits: Oceanico
