AFTER 10 months of building his $1.1 million sailing masterpiece, Noosa Marine shipwright Julian Griffiths was forced this week to take off one end of his work shed to let the cat out.

This 53-foot twin-hulled thing of beauty, called Mojo, had taken five boat builders and the expert input of an interior designer to mastercraft at the Noosaville worksite before being loaded on to a house mover for launch in the Noosa River early on Wednesday morning.

"Ever since it was unloaded in four pallets, we have built this from scratch," said the 41-year-old, whose passion has been building the best boats he can since leaving school in Noosa in Year 12.

The composite material catamaran has been united with the 21-metre carbon-fibre mast created in New Zealand and will undergo sea trials and sail testing out in Laguna Bay in the coming weeks.

All of Julian's 20 years of shipwright skills painstakingly learned at Norman Wright and Sons in Brisbane, then later at Noosa Cats and Stallion Marine before he branched out on his own, have been lavished on this latest creation.

It was ordered by ocean-going Gold Coast retiree Peter Wilcox, who will be putting the boat's sleek lines to the test in the Brisbane to Gladstone before heading over to Thailand for some serious racing.

Julian and his former gun apprentice, Max Marian, who is now a qualified shipwright, will have little time to rest on their laurels as they have to build a slightly smaller version for another client as word spreads of this home-grown Noosa talent.

One of their forward orders is from the US city of Seattle.

Both the boss and his offsider love their work and live to sail - the more competitively the better on the Noosa River or out on the open ocean.

Julian has raced in the Brisbane to Gladstone and Max is a winner of the Bay to Bay race from Tin Can Bay to Hervey Bay.

"We built our own boat - the Noosa 620 - and take on all comers and beat them," Julian said.
