Sea trials on the Whanganui River
This allows any function – radar, sounder, GPS chartplotter or wind data – to be on either Navpixel monitor. The NSO processors can also split the Navpixel screen into quarters if necessary so all the navigational data can appear on one monitor, offering great redundancy in the unlikely event that one monitor or NSO processor should fail. The Titiroa's remote working location meant faults had to be planned for in the system. "This was one of the criteria set by Real Journeys and the Simrad NSO system offers this," said Bart Meltzer from ATL.
"Furthermore, we have included a Simrad RC42 rate compass. This allows extremely accurate and stable chart/radar overlay, along with 10 targeted "mini-ARPAs (for radar-tracking other vessels)," said Bart. Also supplied was the Panasonic closed circuit colour

television system, ICOM VHF communication, an Asus/Toa audio-visual system and an AI phone intercom. The specialist paint systems required for the vessel were prepared and applied by DR Marine Limited from Palmerston North, who, as marine paint applicators, have developed a longstanding working relationship as sub contractors to Q-West. "It is important to be able to maintain the flexibility to work within and around the constraints of a busy yard
and boatbuilders meeting tight deadlines," said painter Daryl Stephens. "To do this means working odd hours while watching drying temperatures all the time to ensure a quality finish," he said.
The various coatings used on the vessel incorporate a duplex approach, with International Marine Coatings and Devoe High Performance Coatings supplied by Akzo Nobel Coatings NZ Ltd. Real Journeys' commitment to preserving the local and global environment meant premium quality paints were a must. Akzo Nobel say that the hull system below the waterline, with Intersleek 970 non-biocide fluoropolymer foul release coating, benefits operators working in fresh water by reducing fuel consumption, engine operating temperatures and lower exhaust emissions.
"An International/Devoe Coatings system was applied to the topsides providing long-term corrosion protection and hard- wearing long-asting aesthetics." Although the Titiroa was built for Lake Manapouri, she could have just as easily slotted into any one of a number of ferry services around New Zealand. She has excellent seakeeping ability, while being able to deal with the extremes of hot and cold and the many wet days Fiordland experiences each year. Her décor and seating are practical, pleasing to the eye and have a friendly, open plan layout. The café is for'ard on the lower deck, where passengers can sit comfortably while enjoying coffee or snacks.
On the upper deck, the for'ard-facing seating and saloon is open to the bridge, although discretely unimposing barriers protect the crew space. The crew soon discovered the Titiroa is very easy to operate and say she has already exceeded everyone's expectations.
