REGENT's Seaglider completes first crewed flight, reviving Soviet-era ground effect technology
Electric 'flying boat' prototype combines boat convenience with aircraft speed for coastal travel.
1Historic first flight
REGENT's Viceroy Seaglider completed its first crewed test flight in Narragansett Bay, covering 1,956 feet at 33 feet altitude for 30 seconds. The 12-passenger prototype uses 12 electric propellers and hydrofoils to transition from boat to aircraft mode. This demonstration validates the wing-in-ground-effect (WIG) technology that enables the craft to fly efficiently just above water surfaces. The startup aims to commercialize this hybrid vessel for coastal transport, offering 180 mph speeds with zero emissions.
2Soviet-era inspiration
The Seaglider revives the Soviet ekranoplan concept from the Cold War, which utilized ground effect aerodynamics. These massive craft could carry heavy loads by flying within one wingspan of water, with the most famous being the 380-ton 'Caspian Sea Monster.' However, original ekranoplans faced operational challenges like rough water takeoffs and difficult docking. REGENT's modern iteration addresses these issues through retractable hydrofoils and electric propulsion, creating a more practical implementation of the technology for contemporary markets.
3Military interest grows
The U.S. military has shown strong interest in REGENT's technology, with $15 million in contracts from the Marine Corps and development agreements with Special Operations Command and Coast Guard. Field demonstrations have proven the Seaglider's potential for beach extractions, medical evacuations, and open-water rescues. A smaller autonomous version called 'Squire' is being developed for 50-pound payload missions. The military sees advantages in the craft's stealth capabilities, payload capacity, and quiet electric operation compared to helicopters.
4Technical specifications
The current Seaglider design carries 12 passengers or 3,500 pounds of cargo at 180 mph, with a range of 180 miles per charge. Hydrofoils initially lift the hull from water before retracting during flight. This dual-phase operation combines boat accessibility with aircraft speed, requiring no traditional runway infrastructure. The electric propulsion system offers environmental benefits and reduced noise compared to conventional aircraft or helicopters, making it suitable for sensitive coastal environments.
5Commercial potential
REGENT positions the Seaglider as a high-speed electric ferry solution for coastal communities, connecting towns faster than conventional boats. The company emphasizes the smoothness and safety demonstrated in test flights as key selling points. By eliminating the need for airports and reducing infrastructure requirements, the craft could create new transportation networks in island nations and archipelagos. The dual commercial-military development strategy helps secure funding while proving the technology's reliability.
6Operational advantages
Compared to helicopters, the Seaglider offers greater payload capacity (12 passengers vs. typical 6-8 in medium helicopters) and significantly lower noise levels. Its water-based operation eliminates the need for expensive helipads or runways. The craft's ability to transition between floating and flying modes provides flexibility in varied maritime conditions. These characteristics make it particularly suitable for medical evacuations, island hopping, and coastal surveillance missions where traditional aircraft face limitations.
7Development timeline
Following the successful crewed test flight, REGENT plans to move into full-rate production. The company has spent years refining the hydrofoil and ground effect systems to ensure stable operation. Next steps include expanding the flight envelope, testing in rougher conditions, and securing regulatory approvals. Commercial operations could begin within several years, initially targeting short-haul coastal routes where the technology's speed advantage is most pronounced over conventional ferries.
8Industry implications
The Seaglider represents a potential paradigm shift in coastal transportation, bridging the gap between maritime and aviation sectors. Its success could spur development of similar WIG craft for various applications, from cargo transport to emergency services. The technology's energy efficiency and infrastructure-light operation make it particularly relevant as regions seek sustainable transport solutions. While challenges remain in scaling production and achieving certification, REGENT's progress demonstrates the viability of modernized ground effect vehicles.
