Austhai Marine
Austhai AT1150 series
The AT1150 is our signature vessel. With over 32 boats built and delivered for a variety of applications including diving, resort transportation and smaller day trip operations, its no wonder that our customers keep coming back to order more.
This model is an improvement of our AT1100, which has been taken out of production. We lengthened our proven hull design to 11.5 meters so it offers all of the advantages of the original but with added space.
It features the same seaworthy hull, economy of operation and maintenance free construction but with a huge cockpit area, making it a top choice amongst discerning dive shop and tour operators.
It is available in several variations for either inboard or outboard engines and is suitable for carrying up to 26 people comfortably.
