Vertical Aerospace Official Press Release

At the 5th edition of the Catarina Aviation Show in São Paulo this week, the future of Latin American coastal mobility is taking center stage. According to an official company statement from REGENT Craft, Brazilian aviation services company Synerjet Corp is showcasing its commitment to zero-emission maritime transit following a landmark order for 10 all-electric Viceroy Seagliders.

The agreement, which industry research notes was officially formed on February 4, 2026, positions Latin America as a primary market for wing-in-ground-effect (WIG) vessels. With over 32,000 kilometers of coastline and heavily congested coastal highways, the region presents a compelling use case for alternative transit solutions. Deliveries of the 12-passenger vessels to Synerjet are slated to begin in 2029.

We are seeing a distinct shift in how regional operators view coastal logistics. By bypassing traditional airport infrastructure in favor of direct shoreline boarding, the Seaglider aims to capture a significant share of the estimated two million passengers traveling along accessible Latin American routes annually.

Transforming Latin American Coastal Travel

Slashing Regional Travel Times

REGENT Craft’s announcement highlights dramatic reductions in travel times for notoriously congested Brazilian routes. By utilizing coastal waterways instead of gridlocked highways, the Seaglider offers a high-speed alternative for both commuters and tourists.

According to the company’s route projections, the journey from Florianópolis to Bombinhas, which typically takes two hours by car, will be reduced to just 20 minutes by Seaglider. Similarly, the trip from Rio de Janeiro to Búzios will be cut from three hours to a mere 45 minutes. Industry data also points to potential future routes, including a 20-minute transit from Santos to Ilhabela, as well as international connections like Buenos Aires to Montevideo.

The Technology Behind the Viceroy

The Viceroy Seaglider is a 100% battery-electric vessel that operates exclusively over water. According to technical specifications provided in industry research, the craft measures 57.5 feet in length with a 65-foot wingspan. It is designed to carry 12 passengers and two crew members, or up to 3,500 pounds of cargo.

The vessel operates in three distinct modes to ensure safety and efficiency:

• Hull Mode: The craft floats on the water for safe, low-speed navigation near docks.
• Hydrofoil Mode: As it accelerates, it rises on underwater foils to skim smoothly over waves.
• Flight Mode: At higher speeds, it takes off to fly within a wingspan of the water’s surface (30 to 60 feet), utilizing aerodynamic “ground effect” to cruise at 160 knots (approximately 180 mph).

Currently, the Viceroy boasts a range of 160 nautical miles, with REGENT projecting an extension to 400 nautical miles as next-generation battery technology matures. Furthermore, the electric propulsion system produces zero direct emissions and operates 30 decibels quieter than traditional aircraft or helicopters.

Strategic Partnerships and Industry Impact

Leadership Perspectives

The partnership between REGENT and Synerjet, a well-known distributor for Pilatus fixed-wing aircraft and Leonardo helicopters, marks a significant diversification into sustainable maritime mobility for the Latin American operator.

“REGENT’s Seaglider represents a compelling new category of mobility. By combining aircraft-like speed with dock-to-dock convenience… [we can] unlock new regional routes,” stated Fabio Rebello, CEO of Synerjet, in a recent industry report.

REGENT’s leadership echoed this sentiment, emphasizing the alignment between the vessel’s capabilities and regional market demands.

“Synerjet understands the expectations of customers who value speed, reliability, and an elevated travel experience,” noted Billy Thalheimer, Co-founder and CEO of REGENT.

Regulatory and Cost Advantages

A critical factor in the Seaglider’s commercial viability is its regulatory classification. Legally, the Seaglider is classified as a maritime vessel rather than an airplane. Industry research indicates it will be certified under maritime rules by the U.S. Coast Guard and international bodies such as Lloyd’s Register and Bureau Veritas.

This classification yields substantial cost efficiencies. The vessel does not require traditional aircraft-pilot licensing, it can be operated by a trained mariner, uses no aviation fuel, and avoids costly airport fees. Consequently, operating costs are projected to be significantly lower than those of business jets or regional helicopters.

Recent Developments and Future Outlook

Testing and Manufacturing Scale-Up

REGENT is actively advancing its testing and production capabilities. In March 2026, the company resumed sea trials with its full-scale Viceroy prototype in Narragansett Bay, Rhode Island. The following month, they began flight-testing a smaller autonomous drone variant, dubbed “Squire,” to validate control systems. To meet a commercial order backlog that exceeds $10 billion globally, REGENT is preparing to open a 255,000-square-foot manufacturing facility in Rhode Island in the summer of 2026.

AirPro News analysis

The introduction of the Seaglider to the Latin American market is more than a novel technological deployment; it represents a structural shift in regional transit economics. We note that the recent formation of the Brazil Seaglider Initiative (BSI), a consortium of local government, private sector, and community stakeholders, signals strong localized support. By advocating for the adoption of seagliders to modernize maritime transport and eliminate greenhouse gas emissions, the BSI provides a crucial political and infrastructural runway for Synerjet’s 2029 delivery timeline. If the regulatory framework holds and battery technology scales as projected, coastal WIG vessels could rapidly cannibalize short-haul regional helicopter and automotive transit markets in coastal hubs.

Frequently Asked Questions (FAQ)

What is a Seaglider?

A Seaglider is a wing-in-ground-effect (WIG) vessel that operates exclusively over water. It floats on a hull at the dock, rides on hydrofoils at moderate speeds, and flies just above the water’s surface at high speeds (up to 180 mph) using aerodynamic ground effect.

When will the Seagliders be delivered to Brazil?

According to industry data, deliveries of the 10 Viceroy Seagliders ordered by Synerjet Corp are scheduled to begin in 2029.

Do Seagliders require airports?

No. Seagliders are classified as maritime vessels and operate dock-to-dock, completely bypassing traditional airport infrastructure and associated fees.

How many passengers can the Viceroy carry?

The REGENT Viceroy model is designed to carry 12 passengers and two crew members, or up to 3,500 pounds of cargo.

This article is based on an official press release from Eve Air Mobility.

Eve Air Mobility (NYSE: EVEX), a global leader in advanced air mobility and a spin-off of Brazilian aerospace manufacturer Embraer, has successfully concluded the hover and low-speed flight test block for its full-scale electric vertical takeoff and landing (eVTOL) engineering prototype. The completion of this phase marks a critical milestone in the aircraft’s development, generating high-fidelity data that validates the company’s aerodynamic models and control laws.

According to the company’s press release, this testing phase was designed to expand the flight envelope step-by-step. By validating models and aircraft behavior against real-world data before advancing to more complex maneuvers, Eve is laying a disciplined technical foundation. The successful closeout of these low-speed tests clears the path for the highly anticipated transition flight testing phase, which is expected to commence in the summer of 2026.

Backed by Embraer’s 55 years of aviation certification expertise, Eve has adopted a methodical, building-block approach to its flight test campaign. This strategy aims to tighten the correlation between simulation predictions and actual flight behavior, ensuring safety and reliability as the program advances toward commercial certification and entry into service.

Flight Test Achievements and Performance Metrics

Pushing the Low-Speed Envelope

The recently completed test block yielded significant operational data. According to the official release and supplementary program data, the uncrewed prototype completed 59 flights, accumulating a total of 2 hours, 27 minutes, and 33 seconds of flight time. During these tests, the aircraft reached a maximum altitude of 215 feet above ground level (AGL) and achieved a maximum single-flight duration of 3 minutes and 48 seconds.

Testing initially focused on a low-speed input phase below 15 knots to validate control laws, downwash effects, thermal behavior, and the propulsion model. As the campaign progressed, operations expanded to approximately 20 knots of ground speed. During this expanded envelope, the engineering team successfully executed simultaneous four-axis maneuvers, which are crucial for validating aerodynamic and load models under dynamic conditions.

System Validations and Firsts

Beyond basic flight metrics, the test block included several notable technical demonstrations. Eve reported the successful execution of more than 100 specific flight test points. Crucially, the aircraft demonstrated its autoland capabilities and a “simplified fly-by-wire mode” for the first time. This simplified mode serves as a secondary, backup layer of the flight control system, designed to activate if the normal fly-by-wire mode becomes unavailable.

The company also noted that recorded noise levels remained in line with expectations, while both battery and propulsion performance exceeded initial projections.

“Completing hover and low‑speed testing gives us high‑confidence data to validate and refine our aerodynamic, propulsion and load models. That model correlation is what enables disciplined envelope expansion. With planned ground tests next, we will be ready to begin transition flights, in which we validate the lifter-pusher synchronization before moving on to the cruise phase.”

Marcelo Basile, Head of Tests at Eve Air Mobility

The Road to Transition Flights

Preparing for Summer 2026

With the hover and low-speed block complete, Eve’s engineering prototype will now undergo a series of planned ground tests. These tests are a prerequisite for the transition flights block, which the company expects to begin in July or August of 2026. The transition phase will focus on expanding the flight envelope further, specifically validating the synchronization between the vertical lifting rotors and the rear pusher propeller as the aircraft shifts to wing-borne forward flight.

“Closing this phase validates the discipline behind our flight test strategy. Across 59 flights, we confirmed stable hover performance and predictable control behavior within the envelope, while expanding our understanding of loads, aerodynamics, propulsion and energy management, key foundations for the transition phase and the certification path ahead with the conforming prototypes.”

Johann Bordais, CEO of Eve Air Mobility

Aircraft Design and Market Position

Lift + Cruise Configuration

Eve’s eVTOL utilizes a “Lift + Cruise” configuration. The design features eight dedicated fixed-pitch rotors for vertical lift and a rear pusher propeller for forward cruise flight, all supported by fixed wings. By eliminating complex tilting mechanisms, the company aims to prioritize safety, mechanical reliability, and a more straightforward certification path.

The 100% electric aircraft is designed to carry four passengers and one pilot at launch, with a targeted range of 100 km (60 miles). This range is optimized for high-frequency urban air mobility (UAM) routes. Future iterations of the aircraft are planned to accommodate up to six passengers once autonomous, uncrewed operations are certified.

Industry-Leading Backlog and Ecosystem

Eve Air Mobility benefits heavily from its relationship with Embraer, which remains the majority shareholder with an approximate 70% stake. This backing provides Eve with access to over 800 contracted engineers and a global service center network.

This robust corporate foundation has translated into significant market confidence. Eve currently holds the largest customer order backlog in the UAM industry, boasting letters of intent for approximately 2,800 aircraft, representing a potential $14 billion in revenue. Furthermore, the company is developing a comprehensive UAM ecosystem, including Eve Vector (urban air traffic management software) and Eve TechCare (aftermarket services).

AirPro News analysis

We observe that Eve Air Mobility is playing a strategic “tortoise and hare” game within the broader eVTOL sector. While competitors such as Joby Aviation and Archer Aviation have already pushed through to transition flights, Eve has deliberately adopted a more incremental, simulation-heavy approach. By leveraging Embraer’s deep institutional knowledge of aviation certification, Eve is prioritizing model correlation over rapid physical milestones.

The upcoming Summer 2026 transition phase represents the ultimate engineering hurdle. Transitioning from vertical rotor lift to wing-borne aerodynamic lift involves passing through a complex, low-speed “grey zone.” Successfully navigating this phase will be a massive de-risking event for the company and its investors. Despite being slightly behind some rivals in physical flight testing timelines, Eve’s methodical strategy, coupled with its industry-leading backlog of 2,800 aircraft, suggests that the market values certification certainty and manufacturing pedigree just as highly as early test flight footage.
