High-Speed Craft Vessels
1,858 high-speed craft vessels tracked worldwide
High-speed craft (AIS type 40–49) are vessels engineered to travel at speeds significantly above those of conventional displacement-hull ships, typically exceeding 30 knots. The category includes hydrofoils that lift above the water surface on underwater wings, hovercraft (air-cushion vehicles) that ride on a pressurized air bubble over water or land, high-speed catamarans and trimarans using slender twin or triple hulls to reduce wave resistance, and wing-in-ground (WIG) effect craft that fly just above the water surface using aerodynamic ground effect. These vessels are regulated under the IMO’s International Code of Safety for High-Speed Craft (HSC Code), which imposes enhanced requirements for structural strength, stability in damaged conditions, fire safety, navigation equipment, and crew training beyond standard SOLAS provisions. High-speed craft are commonly deployed on inter-island passenger routes, military patrol and interception missions, offshore crew transfer, and emergency medical evacuation services where rapid transit times are operationally critical.

Subtypes of High-Speed Craft
The high-speed craft category includes hydrofoils — vessels with submerged wings that lift the hull clear of the water at speed, dramatically reducing drag (Boeing 929 Jetfoil, the Russian Meteor and Kometa series, modern Italian Rodriquez foils). Hovercraft (air-cushion vehicles) ride on a pressurized cushion of air created by lift fans within a flexible skirt — the Saunders-Roe SR.N4 cross-Channel hovercraft and military LCAC landing craft are classic examples. High-speed catamarans use slender twin hulls to minimise wave-making resistance — the Australian-built Incat and Austal wave-piercing catamarans dominate this segment. Trimarans add a third hull for stability at speed. Wing-in-ground (WIG) effect craft fly just above the water surface using aerodynamic ground effect.
How High-Speed Craft Operate
HSC are designed for routes where short transit time outweighs higher fuel cost and reduced cargo capacity. Operators run scheduled service on inter-island and short-sea routes, repeating multiple round trips per day. Maintenance is intensive — high-speed propulsion, water-jet drives, and gas-turbine engines on some designs require frequent inspection. Wave height limits operations: most fast catamarans suspend service in significant wave heights above 2.5–4 metres for passenger comfort and safety. Crew complement is small — typically 5–10 people for a 300–500 passenger fast ferry. Operating speeds of 35–45 knots are typical, with some HSC exceeding 60 knots. Fuel consumption per passenger-mile is significantly higher than conventional ferries, which is a primary commercial constraint.
Tracking High-Speed Craft with AIS
HSC transmit AIS like other vessels, but with reporting characteristics shaped by their speed. AIS Class A reporting interval drops to 2 seconds at speeds above 23 knots — useful for collision avoidance with crossing traffic. The high SOG values on the live map make HSC easy to spot. Patterns reveal operational tempo: regular fast catamaran shuttles between Hong Kong and Macau, ferries between Naples and Capri, hydrofoils on Mediterranean and Adriatic routes. The category overlaps significantly with passenger and pilot vessel transponder profiles — many HSC are passenger fast ferries or offshore crew transfer craft.
Where High-Speed Craft Are Deployed
HSC are commercially viable where routes are short enough that speed savings justify the operating cost. Major civilian deployments include Hong Kong–Macau, Athens–Cycladic islands, Naples–Capri/Ischia, English Channel (historically), Tokyo–Izu islands, Korea–Japan, Hawaii inter-island, and the Strait of Magellan. Russia operates extensive Meteor hydrofoil services on the Volga and Volga–Don river systems. Patrol HSC are common in coastal navies, including the U.S. LCS and various European designs. Offshore wind-farm crew transfer vessels increasingly use small high-speed catamarans for wind-technician shuttles.
Regulations and the HSC Code
High-speed craft operate under the IMO's International Code of Safety for High-Speed Craft (HSC Code), in force since 1996 and revised in 2000. The HSC Code imposes enhanced requirements compared to standard SOLAS — structural strength to handle high-speed wave impacts, stability in the damaged condition appropriate for slender hulls, fast-acting fire-suppression systems, navigation equipment with redundancy, and crew training specific to high-speed operations. Crew must complete HSC type-rating courses for the specific vessel design. Wave-height operating limits are imposed by class society and route certification. The HSC Code applies to passenger vessels above 100 GT and cargo HSC above 500 GT operating internationally.
