Delta Marine
An Overview of the Shipyard's History, Specialty, Iconic Builds, and Partnershipsa
Delta Marine
Shipyard History
One of America’s respected yacht brands, Delta Marine produces high custom motor yachts up to 73 metres long. Based in Seattle, Delta is a family-owned yard that prides itself on producing high-class luxury yachts. Founded in 1968, the company has established itself as a premier builder of custom yachts. Delta Marine’s roots are in building hardy commercial vessels capable of taking on any seas. The story of Delta Marine begins with the visionary entrepreneur, J. Howard Sheldon. With a passion for boating and an eye for innovation, Sheldon set out to create a shipyard that would redefine the standards of yacht construction. In its early years, Delta Marine focused on building commercial vessels and military boats, honing their skills in construction and engineering. However, it was in the 1980s that the shipyard transitioned into luxury yacht building.
The shipyard's relentless pursuit of perfection led to numerous accolades and awards for their yachts, solidifying their position as a leader in the luxury yacht market.

Notable deliveries and models
Delta Marine is recognized for building full-custom motor yachts, delivering vessels in both semi-displacement and full-displacement hull configurations.
The largest yacht built by Delta Marine is the 73.2m LAUREL, completed in 2006. Throughout the 2010s, the American shipyard delivered a series of notable motor yachts, including the 65.5m INVICTUS in 2013, the 72.2m ALBATROSS in 2016, since lengthened and renamed MOONSTONE, and the 63.4m SATORI in 2018.
More recent additions to the Delta Marine fleet include the 46.3m motor superyacht ARCTIC PRIDE II, delivered in 2020, and the 33.5m VAGABOND, a Delta 110 model that introduced a new hull platform for the Seattle-based shipyard when she was launched in 2025.
Design collaborations on models and projects
Delta Marine’s design capabilities rest on a large in-house engineering and design team, the Delta Design Group. Operating out of state-of-the-art facilities, the team works closely with the yard’s build teams and clients to create high-quality custom builds, while the yard also collaborates with outside design teams.
The Delta Design Group has contributed immensely to the success of a range of projects, including LAUREL, the 47.5m ROCHADE, INVICTUS, the 40.5m ONIKA and SATORI. These motor yachts are known for their integration of design and engineering, well-considered interior layouts, careful attention to detail and impressive finishes, with ONIKA winning the Interior Design Award (Motor Yachts below 500GT) at the 2015 ShowBoats Design Awards.
Delta Marine has collaborated with acclaimed yacht designer Jonathan Quinn Barnett on multiple projects. Barnett’s signature sleek and elegant designs have graced the exteriors of the 46.2m PISCES and the 53m MLR, and he also designed the interiors of MLR and the 37.8m RUFFIAN.
The yard worked closely with the acclaimed Norwegian designer Espen Øino on MOONSTONE (ex-ALBATROSS). Øino’s design expertise and ability to combine elegance with functionality were instrumental in shaping the yacht’s exterior profile, with naval architecture by the Delta Design Group and interiors by Zuretti. Delta Marine has also partnered with British design studio Bannenberg & Rowell on the Delta + B&R range, a family of hybrid superyacht designs spanning 50m to 75m, starting with the Delta 50BR.
