TRUE MAIN SYSTEMS

Propulsion and power

The engine is a 50hp Isuzu driving a fixed propeller (which has replaced the Kiwiprop) on the centreline. The engine is under the cockpit but is accessible from front and one side. The whole of the area under the saloon sole and the fin keel form the 700 litre fuel tank (almost enough to motor to Fiji!). There is 150 litre ‘day tank’ with a transfer pump from the main fuel tanks.


In addition to the usual alternator, which usually charges the starter battery, there is a high capacity alternator that only cuts in over 1000rpm charging the main batteries (4x 120Ah), giving typically 40amp at 1800rpm. Power is also provided by the Air-Breeze wind generator (with the on/off switch by the bed in the aft cabin, so it can be turned off at night); and from a solar panel,which has recently been replaced. There are plenty of ammeters and switches so the system can be managed.


Water

There are three water tanks, one to each side of the saloon, and one aft. There are interconnecting pipes and valves to enable water management. Interestingly, the tanks are filled from deck scuppers. The deck drains overside till the salt and dirt have been washed off. Then Y-valves on each side are switched over so that water drains from the deck via large filters into the port and stbd tanks. (I switched the valves over at 0730 at Great Barrier when we had APD rain, and the tanks were full before 0900). This arrangement is useful because getting good quality water can be tricky in NZ once clear of Auckland. The total water capacity is about 750 litres.


Navigation

At the Nav station there are VHF and SSB radios; an old autopilot with a large control panel. It works well, but cannot be controlled from the cockpit, and is high up the list of items to be replaced.


There is a Furuno radar, and an independent GPS. Nav data such as SOG, COG, speed and windspeed are fed from the Simrad instruments  and the GPS to the radar display; then on to a laptop  at the navstation. We use Australian SOB software .


Unfortunately, the compass for the autopilot does not have an NMEA output, so heading data is missing.  The navigation system uses C-Map MaxPro.


There is a completely independent Navman plotter by the ships wheel in front of the helmsman. This uses C-Map NT cartridges.


Hull


The hull is solid grp, and has been epoxy painted. It is in generally good condition. Teak decks have recently been removed and replaced with painted glass over ply, The coachroof is glass over ply, a form of construction common in New Zealand. It seems to be in good condition with no evidence of water ingress. The rudder is fully skegged.
