What is a Seaglider?

A seaglider is an all-electric, passenger-carrying, wing-in-ground-effect vehicle built to service coastal routes, building on real-world-proven tech. 

Float. Foil. Fly!

Seagliders operate as nautical transport vessels that begin floating on a hull before transitioning to gliding on underwater hydrofoils and ultimately taking off to fly above the water’s surface staying in ground effect. 

Proven Technology

All-electric seagliders are possible due to tested aerodynamic principles and built to the highest safety standards.

Industry Leaders

Seagliders are brought to Hawai’i by world-class engineers in conjunction with local community leaders and organizations

Powered By REGENT

REGENT’s flagship seaglider, Viceroy, is 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 are expected to enter service by mid decade. Full-scale prototypes will begin human flight trials by 2024.


Seagliders can be adopted to fly both passengers and cargo


Seagliders are 100% electric with zero emissions

Built To Serve

Seagliders will provide Hawaii's residents and visitors affordable travel, lower cargo costs, quicker emergency response and reduced highway congestion all without any carbon emissions. The Hawai’i Seaglider Initiative is built on the core value of serving the community with every effort taken to include local voices and ensure that the benefits of seagliders are shared by the entire Hawaiian ecosystem.

Seagliders offer numerous benefits for Hawai‘i.

Good for Our Environment

Seagliders are 100% electric vehicles with zero emissions

Survey of Hawai’i residents show that many believe seagliders can help us meet the Hawa’i Clean Energy Initiative goals

Seagliders help address our state’s largest gap – clean air and maritime transportation

Affordable Travel

Preliminary feasibility study showed strong resident and visitor sentiment that the islands need more affordable passenger and cargo transportation

Seagliders have substantially lower operating costs and simpler infrastructure requirements compared with airplanes which translates to more affordable and accessible travel for residents

Unparalleled Convenience

With no TSA line and speeds of 180 miles per hour, seagliders offer faster and more efficient regional travel than boats and airplanes

Fesibility study results indicate a need and desire for Hawai’i to diversify its transportation system

Emergency Care

Seagliders can be used as air ambulances, transporting patients between the islands or transporting patients for routine follow-up treatment

Seagliders can be used for natural disaster preparedness and supply chain resiliency

Lower Cargo Costs

Bringing down transportation costs between the islands will help bring down the price of goods

Preliminary survey indicates that many residents of Hawai’i believe that Hawai’I’s economy will benefit from a seaglider network due to increased efficiency of inter-island commerce

Reduced Highway Traffic

Seaglider use for intra-island travel will reduce traffic congestion and make travel faster, easier, and less stressful

In a preliminary study, 30% of O’ahu residents indicated that they would be likely to use a commuter seaglider service regularly. On Hawai’i island, 35% of residents support an intra-island route between Kona and Hilo

A Complete System

Seagliders enable more resilient transportation systems that cab bounce back from disruptions

Seagliders charged with renewable energy will help decarbonize our islands

Improve Access to Affordable Housing

Low cost, zero-carbon transportation will help democratize transit across the islands

Expanded service areas and increased access means that more residents can access affordable housing

Initiative Partners

HSI brings together local private, government & non profit sector stakeholders across critical workspaces to further accelerate Hawai‘i’s energy resiliency and clean energy mandates through the adoption of seagliders
