This is the full flybridge version of the 1200 series. Like all Austhai models it is available in a range of layouts, ranging from a 3 cabin personal recreational craft, a game fishing boat, a functional dive and snorkelling boat, and a tourist day tripper or whale watcher.

Power ranges from twin 315 HP inboard diesel to twin 500 HP to give the speed required. Check out some of the layouts available in the concept design section
