Crystal Mahler is a luxury Rhine-class river cruise ship built for Crystal River Cruises at the MV Werften shipyard in Wismar, Germany, and delivered in 2017 as part of a new generation of premium European river vessels. The 135-meter ship accommodates around 110 guests in spacious all-suite cabins and operates itineraries along major European rivers such as the Rhine, Main, and Danube.

Within this project, Prime Baltic Associaties carried out insulation works together with installation of catering areas and piping systems, supporting the integration of technical and service infrastructure required for onboard operations during the vessel’s construction phase.
