Waterfly Technologies, a startup incubated at IIT Madras, is pioneering a new mode of transportation with its electric seagliders. Positioned as a sustainable alternative to traditional air and ferry travel, these cutting-edge Wing-in-Ground (WIG) craft aim to transform coastal transportation with their innovative design and operational efficiency.
Seagliders leverage ground effect technology, allowing them to take off from water, maintain a cruising altitude of approximately four meters, and achieve exceptional fuel efficiency. With speeds reaching up to 500 km/h, they offer a unique blend of aircraft speed and boat-like maneuverability, all at a significantly lower cost compared to conventional aviation.
At Aero India in Bengaluru, Waterfly Technologies showcased its futuristic design, generating considerable interest. The startup plans to develop a 100 kg prototype by April 2025, followed by a one-tonne version later in the year. By 2026, the company expects to unveil a full-scale, 20-seat seaglider capable of carrying a four-ton payload.
Waterfly Technologies envisions a broad operational spectrum for its seagliders. Initially targeting regional routes such as Chennai-Singapore, the company has ambitious plans for intercontinental travel by 2029, including long-haul routes like Dubai-Los Angeles.
To bring its vision to reality, Waterfly is seeking certification from the Indian Register of Shipping by 2026. The company is also exploring defense funding to support military applications in cargo transportation and surveillance. Various industries, including pharmaceuticals and electronics, have shown interest in the technology, attracted by its lower operational costs and reduced carbon footprint.
Key Features and Capabilities
- Speed & Efficiency: Expected to travel at speeds up to 500 km/h, making them faster than ferries and significantly more cost-effective than aircraft.
- Range: Initially, battery-powered seagliders will have a range of 500 km, while a hydrogen-electric variant could extend this to 2,000 km.
- Safety: In emergencies, seagliders can safely land on water, providing a crucial advantage over traditional aircraft.
- Altitude: While primarily operating at four meters above water, they can reach altitudes of up to 150 meters if necessary.
