Delta Marine is a family-owned custom yacht builder based on Seattle’s Duwamish River. Founded in 1967 by brothers Ivor and Jack Jones, the yard began with commercial fishing vessels for the Pacific Northwest before moving into luxury yacht construction in the 1980s.
For buyers comparing used yachts for sale, Delta offers a relatively small but highly individual brokerage market. Each yacht was developed as a custom project, so layout, construction material, propulsion, range, interior design, and operating profile can differ substantially from one Delta to another.
Delta’s current shipyard information notes 52 luxury yachts delivered, with most current projects falling in the 40- to 60-metre range and construction capability extending to 100 metres.
YachtWorld currently shows nine Delta Marine yachts for sale, including eight used yachts and one new custom project. Listings range from approximately 71 to 240 feet.
Current models and descriptions include a Delta 124, 124 Delta Tri-Deck MY, Raised Pilothouse Motoryacht, Expedition, Tri-Deck Motoryacht, Flybridge Motoryacht, Tri-Deck, Custom, and Superyacht.
This small inventory reflects the custom nature of the builder. Buyers should evaluate each yacht individually rather than treating Delta as a conventional model-based production brand.
The 124-foot class is one of the most visible segments of the current Delta brokerage market. YachtWorld currently lists both a 2003 Delta 124 and a 1998 124 Delta Tri-Deck MY.
These yachts represent Delta’s late-1990s and early-2000s custom motor-yacht work, with multi-deck layouts, substantial guest accommodation, and systems designed for long-range cruising.
On yachts of this age, machinery history, generators, stabilizers, paint, electrical systems, HVAC, tankage, teak, and previous structural work should be reviewed carefully.
The current market also includes a 1999 Raised Pilothouse Motoryacht and a 1989 Flybridge Motoryacht. These yachts show the breadth of Delta’s earlier custom motor-yacht work below the largest superyacht classes.
Raised-pilothouse layouts can provide protected navigation, strong separation between guest and operational spaces, and efficient circulation for owner-operated or lightly crewed use.
Flybridge models add elevated outdoor helm and entertaining areas while preserving the substantial interior volume associated with larger custom motor yachts.
Delta’s heritage in commercial and Pacific Northwest vessels naturally influenced its expedition-capable yachts. YachtWorld currently lists a 1991 Delta Marine Expedition yacht, while Delta’s delivered fleet includes several yachts designed for demanding long-range cruising.
The builder’s commercial background and in-house engineering capabilities make expedition and remote cruising an important part of the Delta identity.
Buyers considering an older expedition yacht should focus on range, fuel capacity, tankage, machinery redundancy, tender handling, stabilizers, communications equipment, cold-weather systems, and recent refit history.
Delta announced a new custom 110-foot motor yacht in build in 2025, developed in response to increased demand for fully custom yachts in the 110- to 124-foot range.
The new platform was designed around long-range efficiency while retaining the ability to achieve higher speeds. Delta described the project as a Pacific Northwest-focused family yacht intended for operation with minimal crew.
This project shows that the yard continues to build smaller custom yachts alongside its better-known 50- to 70-metre superyachts.
The current YachtWorld market includes a new 2027 Delta Marine Custom yacht at approximately 63 metres. This listing represents the new-build side of the current Delta market and sits within the size range Delta identifies as central to its present project pipeline.
A custom project at this scale should be evaluated through full build specifications, contract status, delivery timeline, naval architecture, propulsion package, classification, interior design, and owner-change allowances rather than by model name alone.
For buyers comparing mega yachts for sale, a current-build Delta offers access to a fully custom American platform rather than a standardized series yacht.
LAUREL is one of Delta Marine’s most important yachts and remains the yard’s largest build by length at 240 feet, or 73.15 metres. Delivered in 2006, she combines a steel hull with a composite superstructure.
Delta lists approximately 1,595 gross tons, a 40-foot beam, twin Caterpillar 3516B engines, an 18.2-knot maximum speed, and a range of approximately 6,000 nautical miles at 13 knots.
LAUREL demonstrated Delta’s ability to execute a large custom superyacht with long-range performance, substantial interior volume, and advanced engineering at a scale rarely undertaken by American yards.
ALBATROSS is a 236-foot Delta delivered in 2016 and is the builder’s largest yacht by tonnage at approximately 2,066 GT. The yacht represents Delta’s continued development of very large custom superyachts after LAUREL.
INVICTUS is a 66-metre yacht with a steel hull and composite superstructure. Delta describes her as exceeding 1,900 gross tons with a beam of approximately 43 feet and expansive interior volume.
These yachts illustrate the upper end of Delta’s capabilities, combining steel hull construction with lightweight composite superstructures, extensive glazing, and large-volume interiors.
Composite construction is central to Delta Marine’s engineering philosophy. The yard has extensive experience with full-composite yachts as well as steel hulls paired with composite superstructures.
Delta states that composite construction supports strength, efficiency, quiet operation, durability, and long-term performance when engineered correctly.
The shipyard operates from a 25-acre Seattle facility with nearly 300,000 square feet of covered manufacturing space and keeps naval architecture, engineering, hull construction, fabrication, joinery, and finishing capabilities in-house.
When buying a used Delta, buyers should begin with original build documentation, class records where applicable, structural surveys, refit history, and complete machinery service records.
Composite yachts should be inspected for moisture, core condition, bonding, delamination, impact damage, laminate repairs, and paint-system condition. Steel-hulled yachts require corrosion, coating, weld, tank, and plate-thickness inspection.
Mechanical review should cover main engines, transmissions, shafts, propellers, generators, stabilizers, hydraulics, HVAC, watermakers, electrical systems, navigation equipment, communications systems, and integrated vessel-management equipment.
On expedition and large superyacht models, buyers should also inspect cranes, tender systems, shell doors, passerelles, firefighting equipment, crew areas, long-range fuel systems, and redundancy in critical machinery.
A professional superyacht survey, detailed machinery inspection, structural review, class-record review, and sea trial are essential before completing a purchase.
