Seaplanes might seem like a relic of aviation’s golden age, but they never truly disappeared. They’ve been quietly serving remote communities, ferrying adventurers to untouched corners of the world, and making a case for their relevance in modern air travel. Now, with sustainability reshaping the industry, the Polaris hybrid-electric seaplane is stepping in to prove that waterborne aviation isn’t just alive—it’s evolving. Developed by Tidal Flight, this clean-sheet design blends efficiency, versatility, and cutting-edge hybrid propulsion, offering a glimpse into a future where seaplanes become key players in regional travel.
Unlike the rugged floatplanes of the past, Polaris is built for both sustainability and performance. With a wingspan of 59 feet and a takeoff weight of 12,500 pounds, it balances power and efficiency in a way that makes sense for modern operators. At the heart of its design is a hybrid-electric propulsion system, featuring twin electric nacelles mounted on a V-tail empennage. These aren’t just for show—low-tip-speed propellers reduce noise while an internal combustion engine powers a generator, feeding the battery system. The result? An aircraft that slashes fuel consumption by an impressive 85% compared to similar seaplanes.

This efficiency doesn’t come at the cost of capability. Polaris cruises at 162 knots (186 mph) and can carry up to 12 passengers or a one-ton payload. Its range of 1,034 nautical miles ensures it’s not limited to short hops, making it a viable option for island nations, coastal cities, and remote regions where traditional runways are scarce. And while electric vertical takeoff and landing (eVTOL) aircraft have been soaking up investor attention, seaplanes offer a practical, proven alternative for short-haul transport. As Tidal Flight sees it, Polaris isn’t just about sustainability—it’s about making economic sense, too.
The seaplane’s aerodynamic refinements extend beyond its hybrid drivetrain. Foldable sponsons—retractable stabilizers on the wings—help reduce drag when cruising, a small but critical design choice that contributes to overall efficiency. Meanwhile, Polaris’s ability to operate on Sustainable Aviation Fuels (SAF) means it can integrate seamlessly into existing aviation infrastructure. Future versions are expected to transition to hydrogen or fully electric power, but for now, it’s a pragmatic step forward in an industry still working through the challenges of electrification.
Tropic Ocean Airways, a major player in seaplane services, has already recognized the potential. The company has signed a Letter of Intent for 20 Polaris aircraft, a deal worth over $100 million. “Tidal’s quiet, comfortable, hybrid-electric aircraft helps us deliver on our sustainability goals while offering a superior product to our customers and without compromising on range, payload, or cruise speed,” said Founder & CEO Rob Ceravolo. It’s a significant vote of confidence from an airline that knows what works in real-world operations.
Tidal Flight isn’t rushing things. A 1/6th scale model has already taken to the skies, and a full-scale prototype is expected to fly in 2027. If all goes according to plan, passenger service could begin by 2030. That timeline reflects the challenges of bringing a new aircraft to market, but it also shows how hybrid technology is reaching a level of maturity that makes it commercially viable.
In many ways, Polaris is bringing seaplanes full circle. The same aircraft that once pioneered transoceanic flights in the early 20th century are now at the forefront of sustainable aviation. With its combination of range, efficiency, and operational flexibility, Polaris makes a strong case for the seaplane’s resurgence. It’s not just about nostalgia—it’s about what comes next.
