Other Machinery

  • Reverso oil change system with Oberdorfer 24 Volt pump with valved manifold serving generator, main engines and main gearboxes.
  • Delta T automatic fire dampeners on engine room air intake and exhaust. 
  • 3 separate Delta T fans exhaust the engine room while one additional fan provides intake air.
  • Bauer dive compressor with dual output capability.
  • Extensive complement of organised spares.
  • Extensive tool kit with hand, power tools and a variety of specialist items associated with repair and maintenance.
  • There are two complete Fireboy fire suppression bottles in the engine room either of which is capable of suppressing a fire. 
  • These are tied to a Fireboy automatic shut-down control. 
  • If a bottle fires or if the manual release is pulled, the Fireboy control closes the Delta T fire damper while shutting down all diesel consumers.
  • System Overview – she has 240 VAC, 110 VAC, 24 VDC and 12 VDC electrical systems. 
  • The backbone of the system is the 24 VDC system, which consists of a 1,650 Amp hour battery bank. 
  • Charging of the bank is accomplished by an array of 10 solar panels capable of roughly 200 Amp output, two engine driven alternators capable of roughly 360 amp output, and 3 Victron 5 KW inverter chargers capable of roughly 360 amps charging via either shore power or the generator.
  • The inverters also draw power from the battery bank and provide 240 VAC power at a default frequency of 50 Hz. 
  • When connected to shore power or generator, the inverters match the frequency of the source – either 50 or 60 Hz. 
  • The generator provides power at either 50 Hz but normally is run at 50 Hz to save fuel. 
  • All high amp ship’s systems run on either 50 or 60 Hz without any modification. 
  • This includes the air conditioning, watermaker, washer and dryer and similar. 
  • The inverters also will support sources of 240 VAC by supplying additional power from the battery bank when demand exceeds the available supply.
  • Most ship’s systems, to the extent practical, run on 24 volts to draw power directly from the heavy-duty battery bank. 
  • These include, among others, refrigeration, lighting, heater fans, ventilation fans, and electronics. 
  • This permits the shutdown of the 240 VAC inverters when they are not required which reduces consumption. 
  • She is frequently run with the 240 VAC inverters and alternators off when under way, as solar power is sufficient to power the boat. 
  • This can save as much as 5 litres per hour fuel burn on the main engines.
  • 110 VAC power is supplied by a dedicated inverter, which primarily serves a number of US outlets. 
  • 12 VDC is supplied by one of 2 x 24 to 12 VDC converters. 
  • 12 VDC can also be obtained from a centre tap on the house bank. 
  • There are also dedicated 24 and 12 VDC chargers for the engine start and generator start batteries.
