O AirFish: A Inovadora Embarcação de Superfície da ST Engineering

Singapore Firm Debuts Sea-Skimming Craft That Flies Like an Albatross

ST Engineering, an aerospace engineering company based in Singapore, has recently unveiled the AirFish, an innovative 10-seater sea-skimming craft that utilizes ground effect to “fly” at heights between 1 and 3 meters above the ocean surface. This groundbreaking design has the potential to revolutionize the maritime transportation landscape, offering a faster and more efficient alternative to traditional ferries.

How the AirFish Works

The AirFish takes advantage of the ground effect, an aerodynamic phenomenon where the compressed air between the wing and the water’s surface creates additional lift while simultaneously reducing drag. This principle allows the craft to achieve speeds of up to 100 knots (approximately 116 mph), which is three times faster than conventional ferries.

Advantages of Ground Effect

The benefits of utilizing ground effect in maritime transport include:

Increased Energy Efficiency: Reduced fuel consumption due to lower drag.
No Airport Infrastructure Required: Classified as a maritime vessel, eliminating the need for runways.
Sustainability: Potentially lowers maritime emissions, contributing to greener transportation solutions.

Technical Specifications

Here is a table summarizing the key specifications of the AirFish:

Specification	Details
Capacity	8 passengers + 2 crew members
Length	17 meters
Wingspan	15 meters
Range	300 nautical miles
Payload Capacity	Up to 1,000 kg
Operational Condition	Functions in Sea State 3 (waves of 0.5 to 1.25 meters) with winds of up to 15 knots

Commercial Deployment

The inaugural AirFish services are slated to commence in Q2 2026, connecting Singapore and Batam, pending necessary regulatory approvals. ST Engineering has partnered with BatamFast, a ferry operator, to manage this route, where travel time will be reduced to 25 to 30 minutes compared to 40 to 45 minutes with traditional ferries.

In addition to the Singapore-Batam route, a second partnership with Indian operator Wings Over Water Ferries aims to introduce up to four AirFish units in India by the end of 2026. International interest is also on the rise, with Turkish company Eurasia Mobility Solutions requesting 10 AirFish units, with a possibility for more.

Potential Use Cases Beyond Passenger Transport

The AirFish’s technology opens up various possibilities beyond passenger ferrying, including:

Emergency Transport: Rapid response capabilities for medical evacuations or natural disaster relief.
Tourism: Scenic flights offer new ways to experience coastal landscapes.
Cargo Transport: Efficient movement of goods between islands and coastal cities.
Search and Rescue Operations: Enhanced mobility for rescue missions in maritime environments.

Conclusion

The AirFish represents a significant breakthrough in maritime transport, merging energy efficiency with speed. By enabling travel in conditions typically challenging for conventional ferries, ST Engineering is paving the way for novel opportunities in inter-island and coastal city transportation. This innovative technology not only promises to enhance the traveler experience but also contributes to a more sustainable maritime transport ecosystem.
