(BELFAST, Northern Ireland) — Artemis Technologies, a global leader in commercial electric foiling vessels, has signed a memorandum of understanding with Delta Marine to manufacture eFoiler vessels specifically for Washington’s Puget Sound.
This partnership will significantly change the regional maritime landscape, providing an eco-friendly solution that addresses both the environmental and logistical challenges facing the area’s waterborne transit systems.
Artemis Technologies will work alongside Delta Marine to meet the growing demand for zero-emission ferries, including smaller vessels ideal for high-speed, short-haul routes. Washington state, with more ferries than any other region in the U.S., is under increasing pressure to transition to cleaner, more efficient models as public interest in sustainable transportation rises.

The company has grown significantly since its founding in 2017, having invested over $100 million in research and development. Artemis Technologies’ work in vessel electrification reached a key milestone in 2022 with the successful deployment of Pioneer of Belfast, the world’s first commercially coded e-foiling vessel.
The company now offers a portfolio of products that includes the 100 percent electric foiling ferry, the Artemis EF-24 Passenger, and the Artemis EF-12 Escape, a luxury water taxi designed for commuters and luxury travel, launched at this year’s America’s Cup in Barcelona.
Both these models offer a scalable solution for modern, high-speed ferry services, including routes operated by King County Water Taxi and Kitsap Transit. These vessels, optimized for efficiency and lower environmental impact, reflect the “mosquito fleet” style of smaller, more agile ferries that have recently been advocated as a practical solution to Puget Sound’s ferry congestion.
“Our collaboration with Delta Marine enables us to bring our market-leading eFoiler technology to one of the busiest ferry hubs in the U.S.,” said David Tyler, co-founder of Artemis Technologies. “Washington State is ready for this shift to sustainable maritime transit, and we’re proud to offer real-world solutions that address the region’s pressing transportation challenges and environmental goals.
Since establishing its North America operations in New York earlier this year, Artemis Technologies has seen significant interest from U.S. operators and stakeholders. This memorandum with Delta Marine aligns with ongoing partnerships and contracts with notable maritime operators, including Condor Ferries, Orkney Ferries, Brabo, Swedish Maritime Administration, and Red Funnel, underscoring the clean maritime company’s commitment to decarbonizing marine transportation on a global scale.
“Partnering with Artemis Technologies allows us to bring world-leading electrification and foiling expertise to our region,” said Delta Marine Vice President Michelle Jones. “By building these ferries locally, we are supporting Washington’s clean energy objectives and fostering innovation in the U.S. maritime sector.”
Delta was the perfect partner for several reasons. Both companies share a passion for leveraging next-gen technology to create the most efficient, forward-thinking naval architecture, design and construction. Headquartered in Seattle for over 50 years, this Pacific Northwest shipbuilder has been a world leader in composite construction utilizing unconventional solutions, lightweight materials, and creative forms that are progressive in both design and utility. Delta’s journey began with building commercial fishing boats for Alaska’s formidable waters. They have since expanded to create some of the world’s most iconic megayachts.
With the production of Artemis EF-24 Passenger, Artemis Technologies and Delta Marine aim to set a new standard for high-speed, zero-emission vessels in the Puget Sound. This collaboration reflects an ongoing commitment to environmental stewardship and a more sustainable solution to city congestion that will improve the passenger experience and reduce emissions while helping to protect the unique natural resources of Washington state’s waterways.
