Delta Marine Yachts

Located in Seattle, Washington, in the Pacific Northwest, Delta Marine is a family-run shipyard that builds and refits custom superyachts up to 100 metres in length.

History of Delta Marine Yachts

Delta Marine was founded by brothers Jack and Ivor Jones on Seattle’s Duwamish River in 1967. The shipyard’s initial focus was on building fishing boats capable of handling the frequently rough waters of the Pacific Northwest. Delta Marine’s success in the fishing sector led the shipyard to build luxury expedition yachts that could take their owners north to Alaska, west to the Pacific islands, and around the world. By the 1990s, Delta Marine began exclusively building custom superyachts.

Through the years, Delta Marine have drawn on the craftsmanship of their local pool of talented artisans and have continued to develop and refine their composite yacht-construction technology. As a result, the shipyard has launched some of the world’s largest luxury superyachts.

Notable Delta Marine Yachts

In 2008, Delta Marine delivered the 37.6-metre superyacht Marama to owners who took her on a three-month, 3,200-mile voyage of exploration to Alaska and along its coastline. This long-range luxury yacht once again proved the shipyard’s ability to build comfortable expedition motor yachts.

The 64.53-metre superyacht Invictus launched in 2013 featuring a steel hull and composite superstructure. The shipyard’s Delta Design Group provided her exterior styling and engineering, while Diane Johnson Design created her elegant interior design.


Luxury yacht building in advanced composites remains a Delta Marine speciality. In addition to new yacht builds and refits the shipyard offers yacht design and naval architecture, although it also is happy to collaborate with an owner’s outside design team.
