Viceroy is REGENT’s flagship seaglider, a 12 passenger vehicle that operates exclusively over water, traversing the sea in one of three modes: hull, hydrofoil, or flight in ground effect. Seagliders have 160 nautical mile range with existing battery technology (upgradeable to over 400 nautical mile range with next generation battery technology) and will enter service by mid-decade. REGENT will put humans on board full-scale prototypes in 2024.

Specifications and configuration are subject to change, images may not reflect the final vehicle design.

Mission Sets

Passenger Transport

Quick change cabins enables the operator to perform the days mission with minimal downtime.

Mission Sets


Seagliders serve as the ultimate movers of freight.  They bypass congested freeways for wide open waterways. Whether container, pallet or hand load, we efficiently carry 3500 lbs in 834 cubic feet.

Mission Sets


Amazing views, exceptional quiet, incredible speed, and extreme comfort meets unparalleled safety.

Mission Sets

Offshore Logistics

High wave tolerance combined with exceptional cabin configurations makes Viceroy the optimal offshore workhorse.  The seaglider is perfect for moving personnel and equipment safely from shore to rig and back again. 3500 lbs of payload plus 180 mph cruise enable seagliders to deliver the goods where you need them most.

Mission Sets

Search & Rescue

With the ability to respond quickly to any emergency, the seaglider is the perfect platform to get medical personnel IN and patients OUT at a moments notice.  Our three bed interior combined with 3500 lbs of payload ensures that those in need get the urgent care they deserve.

Mission Sets


Seagliders offer a high-speed, low-cost mobility platform to the Department of Defense. Capable of low-signature flight, sensor and communications relay plus rapid infiltration / exfiltration of Special Operating Forces, seagliders are positioned to immediately aid the warfighter in times of peace or high-intensity conflict.




Best-in-class windows enable unmatched viewing experience.  Admire upclose and personal views of the coast, watching the waves safely roll underneath the seaglider while you float on a cushion of air at 180 mph.


Hydrofoils enable smooth rides and high maneuverability in ports.  They are the key enabling difference between seagliders and past ground effect vehicles.  Seaglider hydrofoils retract after takeoff for near-water flight, and redeploy after landing to enable foiling into the terminal dock.

Electric Motors

Electric motors make the seaglider 30 decibels quieter than comparable payload aircraft or helicopters.  In addition, they drastically reduce maintenance cost and completely eliminate emissions from fuel-guzzling combustion engines.

Cargo Door

Large cargo door (6’5” height by 54” width, 1.95m height by 1.37m width) enables convenient cargo loading and makes the seaglider flexible for any mission.


Pointed, deep-V hull enables comfortable landings in multiple sea states. Seagliders can use a deep-V hull because they have hydrofoils for high-speed water transit, and therefore do not need a flat, uncomfortable planning hull.


Distributed ‘blown wing’ propulsion enables low speed, maximum comfort, takeoff and landings.  Safety is enhanced with 8 redundant electric motors.


Onboard safety systems create comprehensive situational awareness for the seaglider captain ensuring the ability to remain clear of obstacles, detect traffic and separate from marine wildlife.



Flat floor, 12 passenger interior for maximum comfort and exceptional views from every seat. Featuring 34 inches of seat pitch, 3000 lbs of payload in the passenger configuration and 88 cu ft of luggage space.


Luxury VIP

Double club interior with side facing lavatory seat occupiable for takeoff and landing.  Travel in total comfort, deafening quiet and experience exceptional views from every seat.  Featuring optional lie flat seating and wi-fi in a standup cabin.
