Austhai Marine
Austhai AT800 series
The AT800 is a popular model, receiving kudos from UK publications Boat Fishing Monthly, Practical Boat Owner and Dive Magazine for it’s trailerable design and offshore capability.
The AT800 is available in three standard variations:
- Cab Cat, a cabin model primarily designed as an overnighter
- Fish Cat, with a center console designed for the serious fisherman
- Fun Cat, a bow rider style side console model perfect for family day trips
Its unique hull design from Albatross Marine offers speed, stability, comfort, seaworthiness, economy and space to a level not normally available in boats of this size.
With a high feedboard, multiple staked chines, large volume hulls and good use of internal space, its suitable for rough waters – whether crossing channels or handling squalls.
It was initially designed as a private use vessel and is suitable for short term outings, making it popular for offshore fishing expeditions for up to 8 people.
