February, 2026 – Article in Superyacht Times
Founded in 1967, Delta Marine is a family-owned shipyard located on the banks of Seattle’s Duwamish River. With more than five decades of naval architecture, engineering expertise and hands-on craftsmanship behind it, the shipyard has evolved into America’s leading builder of fully custom yachts.
From its Pacific Northwest base, Delta has built a reputation not through volume or visibility, but through consistency, delivering yachts engineered for serious cruising, long-term ownership and multi-generational service. Today, that philosophy remains firmly intact as the shipyard enters a new chapter of openness and global collaboration.
A legacy of shipbuilding
Founded by Ivor and Jack Jones, Delta Marine’s early years were defined by the construction of commercial and fishing vessels designed for the demanding waters of the Pacific Northwest. Those projects established the technical foundation that still underpins the shipyard’s work today; an emphasis on structural integrity, practical engineering and craftsmanship that prioritises longevity over trends.
That heritage continues to inform Delta’s modern superyacht portfolio, with every yacht conceived as a capable, open-ocean vessel rather than a seasonal showpiece. “Our roots in commercial vessels shape how we think,” says Michelle Jones. “Even as we build superyachts, the expectation is the same: they must be reliable, capable and built to last.”
The recent passing of Ivor has been felt deeply across the yard, yet his values remain embedded within Delta’s culture. The family and leadership team are committed to carrying forward his long-term vision, one rooted in integrity, accountability and respect for the sea.
The influence of the Pacific Northwest
Delta’s location continues to shape how its yachts are conceived and constructed. Proximity to Alaska, British Columbia and vast, remote cruising grounds has fostered a focus on resilient, high-performance design suited to long-range exploration.
Situated on the Duwamish River, the shipyard benefits from a protected waterway with direct access to the Pacific Ocean, allowing for an efficient transition from build to sea trials and real-world testing.
American craftsmanship with a global reach
Delta Marine is among the few remaining shipyards offering American craftsmanship paired with global design flexibility. Its reputation attracts an international clientele seeking reliability, transparency and technical rigour.
“We’re proud to be an American shipyard, and we’re thoughtful about where we’re going next,” Jones explains. “As we collaborate more globally, we remain anchored in the same standards that have always defined our work.”
Historically discreet and focused on owner privacy, Delta is now entering a more open chapter, sharing greater insight into its design partnerships, evolving portfolio and approach to modern yachtbuilding.
Personalised yachts for every owner
Every Delta project begins with a close, collaborative relationship between the owner, the design team and the shipyard. Decisions are made carefully, balancing design ambition, functionality and budget to ensure the best outcome for each yacht.
The process is deliberately personal, allowing every build to reflect the values, lifestyle and long-term plans of its owner. “No two Delta yachts are the same because no two owners are the same,” adds Michelle. “Our role is to listen carefully and guide the process. When there’s trust on all sides, the yacht that emerges feels both considered and personal.”
Why composite construction matters
Delta Marine is recognised for its industry-leading experience in composite superstructures and full composite builds. The material offers clear advantages, including resistance to rust and corrosion, reduced maintenance, superior insulation and quieter operation.
Delta’s proprietary composite methods have been proven in some of the most demanding waters in the world, enabling the construction of yachts that are strong, efficient and built for longevity. At the same time, the shipyard retains the capability to build in steel or aluminium, ensuring each project is engineered precisely for its intended use.
“Composite construction aligns perfectly with our philosophy,” says Jones. “It allows us to build yachts that are strong, efficient, quiet, and durable. When done properly, it supports performance and longevity in a way few materials can.”
Current and upcoming projects
Delta Marine’s current and forthcoming projects offer a clear expression of how the shipyard’s philosophy translates into practice. Every yacht is built by hand at Delta’s twenty five-acre Seattle facility, where all phases of construction are executed in-house, from design and engineering through to hull construction, fabrication, interior joinery and final finishing. This fully integrated approach, supported by a team of approximately two hundred and fifty naval architects, engineers and craftspeople working side by side, underpins the consistency, quality control and schedule reliability evident across the shipyard’s portfolio.
“Delta’s approach is rooted in craftsmanship, integrity, and a deep respect for the sea,” says Michelle Jones. “Our yachts aren’t built to follow trends, they’re engineered to cross oceans, reflect the values of those who own them, and serve reliably for generations.”
At the larger end of the current lineup, Project Discovery (47.48-metre/156 feet), now in-build, represents a contemporary evolution of Delta’s ocean-going heritage. Developed in collaboration with Dasha Moranova Designs, the yacht combines robust engineering with a wellness-forward onboard lifestyle. Dedicated facilities including a gym, sauna and cold plunge are seamlessly integrated into a flexible deck arrangement, while elegant European interiors sit atop a platform designed for long-range cruising and real-world use.
Also approaching launch is Zembra (45.3-metres/152 feet), a project that reinforces Delta’s reputation for performance-led yacht building. Designed as a globe-trotting vessel, Zembra prioritises efficiency, range and operational confidence, supported by engineering decisions rooted in decades of offshore experience. Her styling is deliberately timeless, allowing capability and functionality to remain at the forefront, qualities that resonate strongly with owners seeking adventure without compromise.
Looking ahead, Delta Longtail (38-metre/125 feet), currently in design, signals a subtle shift in aesthetic direction while remaining true to the shipyard’s core values. Created in partnership with Roberto Curto Design, the concept introduces a more minimal, contemporary profile and compact sophistication, demonstrating how Delta continues to evolve its design language without sacrificing engineering clarity or build quality.
With additional collaborations already in development and a continued presence at Palm Beach and other international boat shows, Delta Marine’s project pipeline reflects both continuity and momentum.
“Our projects vary in scale and style, but they’re all guided by the same priorities: clarity of purpose, sound engineering, and thoughtful execution,” Jones adds.
Continued support beyond delivery
Owning a Delta yacht means joining what the shipyard describes as the Delta family. Support continues long after delivery, with warranty and technical assistance available worldwide.
The shipyard works with trusted international partners and can deploy its own teams globally to oversee maintenance, refit or operational support. Each yacht is assigned a dedicated point of contact who knows the vessel in depth and remains available throughout its lifecycle.
“We stay connected because these yachts are meant to be used, adapted, and cared for over time,” Jones says. “These yachts are long-term commitments, and so are our relationships with owners. Having continuity and real accountability makes a meaningful difference over time.”
Vision for the future
Looking ahead, Delta Marine plans to continue advancing composite innovation and holistic yacht building practices, while remaining true to its American roots and expanding its global reach.
The shipyard will deepen partnerships with internationally recognised design studios, pairing creative vision with proven technical expertise, and aims to attract a new generation of owners seeking reliability, transparency and timeless design.
“The future of Delta is about continuity and evolution,” Jones concludes. “We want to keep building yachts that owners trust completely, while continuing to refine how we design, build, and collaborate for the next generation.”
