The Austhai 1500 WFBI is based on the same hull design as the 1200 series It offers an exceptional ride with the economy that only a well designed catamaran can offer. With a passenger capacity of up to 90 it is a viable alternative for the larger ferry, tour or dive shop operator.

With a power range of up to twin 650 HP, the speed you need is available while the superb hulls give a soft dry ride at maximum economy.
