INSIDE THE CLASSIC WOODEN LAUNCH WIRIHANA – What Powers Her

In the New Zealand classic wooden boating  world there is one designer / builder whose name that no matter who you speak to, is in their top three craftsmen – and that gent is Colin Wild. A quick search of his name in the WW Search Panel will result in a visual show case of NZ’s most striking classic craft.

One of Wild’s finest builds is the 1933 launch – WIRIHANA, a woody that has featured numerous times on WW in the last 10 years. Where ever she goes, I get sent photos from people seduced by her looks.

Aside from her wow factor, WIRIHANA is rather unique in that she is still owned by the third generation of the original owners – the Gould family. The family have had the wisdom to engage retired master boatbuilding icon Chris McMullen to maintain, skipper and use WIRIHANA for 18+ years. Today thanks to Natasha Gould, Chris McMullen and Ken Ricketts we get to uncover a side of WIRIHANA’s past not covered on WW previously – the engine room.

Her original engine was a slow running 4 cyl Kelvin with no reduction gear and  a petrol start. This engine also had a ‘day diesel tank’ fitted to the engine room wall with a gravity feed to the engine with the main diesel tanks aft, from which diesel had to be pumped daily, into the day tank, manually.

Chris McMullen has commented that all the  original associated equipment and day tank, associated with the Kelvin, is still in her today, although not in use, and has the Kelvin name on it.  

As covered on WW previously WIRIHANA was commandeered by the NZ Navy during WWII and when returned to Jack Gould (Natasha Gould’s grandfather) at the end of the war, Jack insisted that the NZ Navy replace the engine, because of the rigours of naval service.  Another reason for the replacement shared by Chris McMullen is probably the fact that reverse gear on the Kelvin had to be inconveniently operated by crew in the engine room. 

End result was the NZ Navy fitted a 6/71 165HP GM Detroit 2 stroke diesel, that had a hydraulic gear box that could be operated by cable. WIRIHANA retained this engine for a great many years and was eventually replaced in the early 2000’s by Rusty Gould (Jack Gould’s son), with a 180hp artificially aspirated 6 cyl. Scania diesel, which she still has today.  

One unusual feature of WIRIHANA’s engine room is the absence of an engine box / sound installation – Chris McMullen told me once , you get used to the noise and its a perfect place for drying towels 🙂
