Alunautic

Alunautic is the aluminium boatbuilding brand of Euro Offshore BV, a Dutch company based in Werkendam in the Netherlands. The yard designs, builds, and distributes welded aluminium craft for the leisure and professional offshore markets - sport boats, workboats, RIBs, landing craft, and custom yacht tenders are all within its scope.

The build we ask Alunautic for, where a programme calls for it, is the custom yacht tender. The yard carries over twenty years of experience in that discipline, working directly with clients to design and construct aluminium tenders to owner specification. The proposition is practical Dutch value: marine-qualified aluminium throughout, CE certification as standard across the range, and a hull geometry shaped for seakeeping, stability, and manoeuvrability rather than showroom aesthetics.

The aluminium RIB range runs from 7.0m to 12.0m in standard lengths, with V-shaped deep-vee hulls and anti-slide, self-bailing decks; custom workboats extend the size envelope to 27.0m. Landing craft are built as twin- or triple-catamaran hulls depending on size, with EOS foam-filled compartments. The Windmill Line is the yard's signature all-conditions workboat series, designed for inland waters and offshore seas alike. Clients include yachting, navy, dredging, rescue, and offshore operators - a spread that reflects the yard's position as a volume-capable, multi-sector aluminium builder rather than a boutique tender specialist. We'd put it alongside other Dutch utility-first yards when a programme needs a durable, repairable, cost-conscious aluminium platform rather than a bespoke composite tender.
