With the introduction of Regent Craft's hydrofoil ground effect glider, the field of coastal transport is about to usher in a storm of innovation. Debuting in Hawaii, this vehicle offers unprecedented speed and comfort with the convenience of an electric boat. This groundbreaking adventure is not just a novel mode of transportation, it is an important step towards a cleaner and more efficient future for short trips.
Inspired by the Ekranoplan (Caspian Sea Monster) of the former Soviet Union, this water glider makes clever use of ground effects to increase lift and reduce drag when the glider is close to the water. Regent has put a modern spin on this design concept to create this high-tech marvel. It perfectly combines the advantages of hydrofoils and wing-to-ground effects, overcoming the limitations that batteries typically face when powering aircraft and boats.
Regent's flagship model, the "Viceroy", is a testament to this innovative design. Capable of carrying 12 passengers and two crew members or equivalent cargo (1,600 kg), this glider will undoubtedly redefine coastal transportation. It can cross the ocean in one of three modes: regular hull gliding, hydrofoil mode, or ground effect flight. It has a range of at least 180 miles/300 km (upgradable to over 400 nautical miles using next-generation battery technology).
With a cruising speed of up to 180 mph (300 km/h), which is six times faster than conventional boats, the glider not only provides unprecedented comfort, but also greatly improves transport efficiency. It can fly at an altitude of 30-60 feet above the surface, which allows it to remain stable in high waves and 30 decibels quieter than an airplane or helicopter.

From an economic point of view, the operating costs of a water glider are expected to be halved compared to conventional aircraft, while it is quiet and emission-free, supporting a cleaner and more efficient mode of transportation. Despite the long charging time, this drawback is negligible in the face of more environmentally friendly and efficient modes of transportation.

The advanced electronic flight control system copes with the technical challenges of controlling such an aircraft, ensuring precision and safety during the flight phases on the water and in the air. This level of automation simplifies smooth operation and allows one-button take-off and landing, a feature that enhances its accessibility and ease of use.
Regent's ambitious project has received significant funding, including nearly $100 million in venture capital and a staggering $8 billion in pre-purchase orders. With the construction of a large manufacturing plant and the successful maiden flight of the first quarter-sized prototype (September 2022), as well as the presentation of a full-scale prototype, the prospects for commercialization of this project are even brighter. In the future, with advances in battery technology, potential models will be able to accommodate up to 150 passengers, and the range will be further enhanced. The influence of this "glider" should not be underestimated, and it will create a revolution in the field of coastal transportation.
Hawaii is poised to become a pioneer in this innovative technology, and Mokulele Airlines is gearing up to become the world's first glider operator. The Hawaii Water Glider Initiative is a multi-stakeholder initiative to establish regular passenger and freight operations that integrate water glider technology into the state's transportation network. This initiative demonstrates a strong commitment to renewable, efficient transportation solutions, with one-way tickets expected to cost as little as $30 between the major islands of Oahu, Maui and Kauai.
This glider uses ground effects to increase lift and hydrofoils to reduce drag for efficient and high-speed flight on the water.
However, the road ahead is not easy. The journey of a water glider is fraught with challenges. Regulatory hurdles pose a significant risk to the success of a project. The main question revolves around whether the water glider is under the jurisdiction of the Federal Aviation Administration or regulated by the U.S. Coast Guard. While the Coast Guard's involvement would mean a simpler and more cost-effective certification process, the possibility of the FAA requiring full certification of the aircraft could jeopardize the project's viability in the United States.

In terms of operational regulations, the unique capabilities and speed of a water glider may require new maritime regulations, especially given its obligation to avoid other vessels on the water. Regent has hinted at technical solutions to these challenges, but the full potential of water gliders remains in an expected state until the regulatory aspects are clear.

Overall, this new glider is not just a new type of transportation, it is a symbol of the evolution of the transportation landscape, the embodiment of the intersection of efficiency, speed and environmental responsibility. As Regent prepares to launch these vehicles, the world is waiting with bated breath in anticipation of a new chapter in coastal and inter-island travel. The future of water gliders is promising, and its successful integration could mark the beginning of a new era in transportation. This is not only the crystallization of technology and art, but also a symbol of human wisdom, indicating that the future of coastal transportation will be better and more convenient, leading us to a cleaner and more efficient future.
