Forget everything you know about the Singapore-Batam crossing. The one-hour ferry ride through the swells of the Singapore Strait — the seasickness, the crowded terminals, the interminable queues at Harbourfront — is about to become a relic. In its place: a craft that flies above the waves at 180 km/h, covering the same distance in under 20 minutes. No runway. No airport. No turbulence. Just a sleek, Singapore-engineered machine skimming a metre above the water's surface, riding a cushion of compressed air like an albatross gliding across the open ocean.

This is the AirFish 8 — and it might just be the most exciting thing to happen to regional travel in Southeast Asia since the budget airline revolution.

What Exactly Is It?

The AirFish 8 is a Wing-in-Ground effect craft, or WIG — a vehicle that exploits the aerodynamic phenomenon known as ground effect. When a wing flies very close to a surface (in this case, the sea), the air beneath it gets compressed, creating an invisible cushion that dramatically increases lift while slashing drag. It's the same physics that allows pelicans and albatrosses to glide effortlessly for kilometres without flapping their wings.

The result is something that looks like a plane, moves like a plane, but is classified as a marine vessel. It takes off and lands on water. It doesn't need a runway, an airport, or even a pier — it can beach itself on sand if necessary. And because it cruises at just one to two metres above the surface, it avoids the turbulence and pressurisation concerns of conventional aircraft.

Built by ST Engineering AirX — a joint venture between Singapore's own ST Engineering and local innovator Wigetworks (now Peluca) — the AirFish 8 carries a crew of two and up to eight passengers. It spans 15 metres wingtip to wingtip and stretches 17.2 metres nose to tail, with a fully composite construction and a distinctive reverse-delta wing that gives it an almost science-fiction silhouette against the waterline.

The Numbers

The specifications read like a techno-thriller:

  • Cruise speed: 100 knots (185 km/h) — three times faster than a conventional ferry
  • Max speed: 110 knots (204 km/h)
  • Cruise altitude: 1–2 metres above the surface
  • Maximum operating altitude: 7 metres
  • Range: 250–300 nautical miles (up to 555 km)
  • Engines: Twin GM LS-series V8 automotive engines, 500 hp each, running on standard 95-octane petrol
  • Payload: 1,000 kg passengers and cargo, plus 160 kg baggage
  • Takeoff conditions: Up to sea state 3 (waves of 1 metre)

To put that in perspective: the Singapore–Batam crossing is roughly 20 kilometres. A conventional ferry does it in 50–60 minutes. The AirFish 8 could do it in under 15. That's not a marginal improvement — it's a category change.

Why Singapore to Batam?

The Singapore–Batam corridor is arguably the most obvious first route for WIG craft in the world. The distance is short. The waters are sheltered enough for reliable operations. The demand is enormous — millions of crossings per year, driven by everything from weekend escapes and golf trips to manufacturing supply chains and the booming Nongsa Digital Park tech corridor.

And the pain points of the current ferry service are well documented. The Harbourfront terminal experience ranges from functional to frustrating. Schedules are limited. The crossing itself can be genuinely unpleasant in rough weather. And for a city that prides itself on efficiency and connectivity, the fact that reaching its nearest international neighbour still involves an hour on a rocking boat feels increasingly anachronistic.

The AirFish changes the equation entirely. At 15 minutes dock-to-dock, Batam suddenly becomes not a day trip but a lunch trip. Nongsa isn't a remote tech hub — it's a satellite office 15 minutes from Marina South. The golf courses of Tering Bay and Batam Hills aren't weekend retreats — they're after-work options. Seafood at the Golden Prawn on Barelang? Dinner plans, not an expedition.

The Technology Has Been Decades in the Making

The AirFish story begins not in Singapore but in Germany, with the late aerodynamicist Hanno Fischer, whose work on ground-effect vehicles spanned half a century. Fischer developed the reverse-delta wing platform that solves the fundamental engineering challenge of WIG craft: inherent stability without complex flight control systems.

In 2004, Singapore's Wigetworks acquired Fischer's entire patent portfolio, intellectual property, and production know-how from Airfoil Development GmbH. The first AirFish 8 made its test flight in October 2016. In 2023, ST Engineering — Southeast Asia's largest defence and engineering group — formed the AirX joint venture to commercialise and scale the technology.

That partnership brought serious aerospace muscle: ST Engineering's modification and certification expertise, Garmin avionics integration, Ray Marine maritime navigation systems, all fused into a single cockpit interface. The pilot doesn't need aviation credentials — a marine captain's licence with additional WIG training is sufficient. "We are not training a pilot, but a boat captain-plus," as AirX general manager Leon Tan puts it.

In February 2024, AirX secured its first international order at the Singapore Airshow — a letter of intent from Turkey's Eurasia Mobility Solutions for up to 10 craft with options for 10 more, to serve Turkey's tourism and coastal transport sectors. Bureau Veritas has signed on for classification and certification under IMO guidelines.

Faster Than a Ferry, Safer Than a Helicopter, Cheaper Than a Seaplane

That's the tagline ST Engineering uses, and the economics back it up. AirX estimates the AirFish 8 is 50% cheaper to operate than a comparable helicopter, while offering three times the speed of marine craft. It runs on standard petrol — no aviation fuel, no charging infrastructure, no hydrogen supply chain. Maintenance is straightforward: automotive V8 engines are well understood, parts are globally available, and the composite airframe requires none of the corrosion management that plagues conventional marine vessels.

The craft is IMO-classified as Type A — meaning it operates exclusively in ground effect, never climbing above 7 metres. This keeps it firmly in the maritime regulatory domain, avoiding the vastly more complex (and expensive) aviation certification process. It's a boat that flies, not a plane that floats.

Beyond Batam: A Vision for the Region

If the Singapore–Batam route proves the concept, the implications for Southeast Asia are staggering. The Philippines' 7,641 islands. Indonesia's 17,000. The Maldives. Japan's Okinawa chain. Australia's Whitsundays. Anywhere that water separates communities and conventional transport is slow, expensive, or unreliable.

ST Engineering has already begun sizing studies on the AirFish X — a 24-to-40-seat variant targeting 2028 service entry. Autonomous systems and hybrid propulsion are under evaluation. Military interest is significant: the U.S. Marine Corps, the Royal Thai Navy, and undisclosed others have tested or expressed interest in the platform for everything from special forces insertion to maritime surveillance to search and rescue.

Studies suggest a global market for 3,000 WIG craft to replace existing ferries, helicopters, and seaplanes. Even a conservative 10% capture rate implies annual production of 25–50 units at $3–5 million each.

What It Means for Singapore

For a nation that has spent decades building the world's most efficient air hub, the AirFish represents something almost poetically fitting: Singapore as the birthplace of a new category of maritime-aviation transport. Not imported technology, but homegrown IP acquired, developed, tested, and scaled right here.

And for anyone who has ever spent a queasy hour on the Batam ferry, the promise is simpler and more immediate: 15 minutes, smooth as glass, skimming above the waves at 180 clicks.

The future of getting to Batam doesn't involve a ferry terminal. It involves a wing.

ST Engineering AirX is targeting commercial operations for the AirFish 8 from 2025. Route-specific announcements for Singapore are expected to follow certification milestones. For more information, visit wigetworks.com.
