Austhai AT1250 series
For the AT1250, we’ve modified our signature AT1150 with a wider beam to double the passenger capacity.
Designed as a mid-level transportation vessel, it can carry up to 60 passengers. Compared to our AT1500, it’s slightly smaller and perfect for day trip operations.
The superb hull design allows for numerous variations of the deck layout. Whether as a sedan, flybridge, bow rider or center console, all configurations are available.
Both inboard or outboard power are available depending on the speed required and the operating environment.
Built models include small ferries, game fishing configurations, dive boats and day tour boats.
