This 12 m 60 passenger vessel was constructed for Nitmiluk (Katherine) Gorge. This vessel is a major investment for the operators being the first new boat in many years. Computational fluid dynamics was used to optimise the whole form, minimising wake and draft whilst ensuring controllability in the restricted waterway. The vessel was built by Custom Works in Darwin from a kit developed by Damien Smith design incorporating custom deck and fender extrusions
