Powered by twin 8V92 (360hp) series Detroit Diesel main engines coupled to Twin Disc gearboxes and non steerable kort nozzles gave her an 11 metric ton bollard pull. Electrical power was provided by two 3-53 series Detroit Diesel engines coupled to 25kW Stamford single phase alternators. A docking was undertaken in 1995 at HMAS Stirling (Garden Island W.A) for a Lloyds hull survey and blast/paint during which time the stern tube seals were upgraded from a packed gland arrangement utilising Neox lubricant to a Chesterton mechanical seal arrangement.

She offered berthing for four and had a rudimentary galley/mess plus shower and toilet facilities and was fully air conditioned.
