North Kingstown, RI, May 29, 2024 – Lloyd’s Register (LR), a global professional services group specialising in providing expert assistance to marine engineering and technology providers and REGENT, the manufacturer of all-electric seagliders for sustainable maritime mobility, announced today that LR will provide certification and advisory services for REGENT’s 12-passenger Viceroy seagliders.  

Seagliders are a novel type of maritime vessel that operate a few meters above the water’s surface, combining the higher speeds of a light aircraft with the low operating costs of a maritime vessel.  

“REGENT’s dedication to safe and sustainable solutions is providing the maritime industry with innovative zero-emissions passenger vessel seagliders that could transform the future of coastal travel," said Mark Darley, COO, Lloyd’s Register. "LR is excited to join with REGENT to proactively set international certification standards for new maritime transportation as the industry evolves.”

“LR’s certification marks significant progress in REGENT’s compliance pathway toward maritime operations," said Ted Lester, VP, Certification, REGENT. "LR’s expertise in classification and compliance services, as well as its commitment to safety and advancing the path to net-zero emissions, make it an ideal partner for ensuring seagliders meet required global standards now and in the future.”

Pioneering maritime mobility
REGENT’s all-electric seagliders represent the latest technology in maritime vessels that drastically reduce the time and cost of transporting people and goods between coastal destinations.  

The novel hydrofoiling wing-in-ground (WIG) craft brings together advanced modern technology from multiple industries – including electric propulsion, hydrofoils, modern vehicle controls, and fly-by-wire systems – to revolutionize WIG capabilities, providing wave tolerance, safe operations, and passenger comfort.

Path to certification
Taking a risk-based approach in the absence of existing rules and regulations, LR will support REGENT through the maritime certification process, including advancing its design basis agreement (DBA) with the US Coast Guard and defining the certification pathway for non-US seagliders. This process and the engineering data derived from this partnership will help define LR rules for future WIG vessels, including REGENT’s 100-passenger Monarch seaglider.  

REGENT aims to have humans on board its 12-passenger seaglider prototype this year, with vehicles to market by mid-decade.

REGENT is pioneering the future of sustainable maritime mobility through the development and manufacturing of all-electric seagliders. Seagliders are a new category of vehicle that combine the speed of an aircraft with the convenience of a boat to deliver an affordable and efficient mode of transportation between coastal destinations. REGENT’s flagship seaglider, Viceroy, is a 12-passenger vehicle that travels at 180mph to service routes up to 180 miles on a single charge. REGENT has already secured more than 600 seaglider orders valued at more than $9 billion from leading airline and ferry operators around the world and has raised more than $90 million from investors including 8090 Industries, Founders Fund, Japan Airlines, and Lockheed Martin.
