THE magnificent Mary River will play host to the Tangalooma Jet for more than five weeks while it visits the Mary River Slipway for a refit.
The vessel's arrival follows that of the H.T. Amorena which recently berthed at the slipway for painting and servicing work.
The catamaran, which calls Tangalooma Island Resort near Brisbane home, is set to have a new engine, new water jets and painting done, worth up to $2.1m.
Tangalooma director of marine operations Jeff Osborne said the improvements would aim to save fuel and add speed.
"The existing engines are 20 years old," he said.
Mr Osborne, whose family owns the resort, said German engineers were being flown in for the new water jets and Cummins motors would work on the engine.
"We've got locals painting .... and a few cranes from locals," he said.
"We've got about 12 Tangalooma staff, engineers, tech guys and electricians in Maryborough for nearly six weeks."
He said Maryborough was chosen for the work as the vessel was so wide not all slipways could accommodate it.
He said it took 19 hours to travel to Maryborough.
"Hopefully it will encourage more work to come to this area," Mr Osborne said.
