GRAND BLUE is a boatbuilding manufactory in Malbork, Poland. We build steel hulls, superstructures and complete interiors – electrics, plumbing, galley and joinery in manufactory quality. No catalogue, nothing off the shelf: we show what we have built.
Steel hulls, cleanly welded and documented – the foundation everything else stands on.
Loft-style superstructures: large windows, clean lines, well-planned layouts.
Complete on-board systems: wiring, water, heating and bathrooms – planned and installed by our own team.
Joinery in manufactory quality: galley, bathroom and built-ins made from premium materials.
Instead of catalogue renderings we show a real boat: the ETESIAS is a luxury houseboat with loft-style living space, an open kitchen, a sauna and a rooftop terrace – designed and built by our team with more than 20 years of boatbuilding experience. She is moored in Berlin and can be visited by appointment.
At our yard in Malbork, boatbuilders, steelworkers, electricians and joiners work under one roof. Every boat is built in station-based production with a documented build file – from the first weld to handover. We prove what we can do on the water, not in brochures.
