AT40 Ferry Boat
High-Capacity Passenger Catamaran for Day Trip Operations
High-Capacity Passenger Catamaran for Day Trip Operations.
Up to 42 passengers. Weather-protected seating. Fast transit speeds. Propulsion systems that keep operating costs low and uptime high. The AT40 Ferry was designed for the economics of running a commercial passenger route.
Built on the AT40 hull platform at AusThai Marine’s ISO-standard facility in Rayong, Thailand.
42 Passengers. On Time. Every Time
Purpose-built commercial hull with weather-protected interior seating. Not a leisure boat stretched to carry more people than it was designed for.
Fast Transit Speeds
22 knots cruise, 25 knots maximum at full load. Twin outboard propulsion delivers the speed inter-island routes demand without the maintenance complexity of inboard shaft drives.
Low Cost of Ownership
Twin outboards service at any dealer across Southeast Asia. Engines tilt clear overnight, eliminating biofouling. Less downtime, lower maintenance spend per operating hour.
Compliant by Design
Built to ISO small craft standards with CE certification. Designed from the outset to meet passenger vessel regulations, not retrofitted to attempt compliance after the fact.
Open and Enclosed Versions
Standard open configuration for scenic routes. Enclosed air-conditioned version for premium routes, night operations, or markets where passenger comfort standards require it. Same hull, same operating economics.
