Brief Overview:

"Mermaid Explorer" was the first of the layout B in the N52 range. This layout accommodates two queen size cabins both with their own ensuites. As the lower cabins are accessed by a centrally aligned corridor directly from the saloon, the pilot house is full width and has two pilot house chairs side by side. In addition, "Mermaid Explorer" was the first N52 to be fitted with the N55 type stack, with styled wings instead of the earlier N47 stack

"Mermaid Explorer" has been lived aboard since she was commissioned and has been maintained by her owners to an exceptionally high standard. This is a rare opportunity to acquire a current, fully loaded, cruise-ready Nordhavn 52 at an attractive price, without the current new-build wait time of approximately eighteen months.  As a further bonus, her equipment has been kept updated.

Located in New Zealand, "Mermaid Explorer" is completely ready to cruise the South Pacific, 5 days to New Caledonia (Noumea), then a hop skip and jump to Vanuatu and Fiji. 3 days to Australia. 

Take advantage of New Zealand’s generous temporary import laws that allow the boat to be left in New Zealand for up to 24 months before any duties are applicable. Take the boat out of the country before the 24-month period expires and get another 24 months upon return. (only applicable to non-New Zealand resident owners). Ideal, keep your boat in New Zealand off season in relatively inexpensive top-class marinas and cruise in in the world most friendly and spectacular cruising grounds. Fuel in NZ is around US$0.75 a liter. (US$2.82 per US Gal) Other benefits may be available to a New Zealand buyer in terms of import duties.


The single Lugger 1066T main engine is a time and distance tested Nordhavn configuration.  With dry stack exhaust and the Nordhavn gravity feed fuel system, the propulsion system is the most reliable of any in service.  It has been tested over many years and millions of cumulative miles, including those racked up over numerous transoceanic passages dating back to the introduction of the Nordhavn 46 in 1988.

The raw water pump on the main engine has been eliminated in the keel-cooled configuration. There is no raw (outside) cooling water intake in the closed circuit to ingest weed, plastic, or marine growth, and therefore, no rubber pump impeller to wear out or disintegrate.  

Exhaust gas from the engine is discharged from the dry stack well above the deck and superstructure to eliminate the “station wagon effect” of pulling the exhaust along with the boat underway.  Exhaust noise is diminished because of the absence of the “water-hammer effect” of the cooling water discharged with the gas at the waterline.


  • Lugger 1066T.2 diesel engine rated at 165 hp at 2,400 rpm
  • Engine has 24-volt 175-amp Leece-Neville large case alternator for house battery bank charging, plus 24-volt 40-amp small case alternator for engine start battery charging
  • ZFW 220 main engine transmission with a 3.96:1 reduction gear
  • Engine analog gauges and Murphy “Powerview” digital display
  • 2-1/4" diameter Aquamet propeller shaft
  • Spurs line cutter on main propeller shaft
  • Propeller is a four-blade 34" diameter x 32" pitch bronze
  • Main engine fuel filter is a Racor 75-900FGX2 (duplex) with valve-over capability from one side to the other
  • Main engine has a guard rail fitted with custom stainless steel sliding tool tray and a tool box professionally mounted
  • Lugger 844D 40 hp wing (“get-home” engine with dedicated propeller shaft and Gori folding propeller.) 
  • Wing engine has its own shaft and propeller.  There is no cross-linking of power to the main shaft, which would be rendered ineffective if fouling of the main engine propeller would occur.
  • Both wing and main engine have Morse cable controls.  Control head and instrument panel are mounted in the pilothouse.  If needed, the wing engine can be started and operated immediately from the pilothouse control station.
  • 2 ea. 835 gal. fiberglass fuel storage tanks with man-sized access ports and internal removable baffles.  Fuel supply pick-ups are at the bottom of each tank to create a simple gravity feed system.  Each tank is fitted with a sight gauge.
  • 1 ea. aluminum 70 gallon aluminum supply (manifold) tank fed by gravity from the storage tanks via ¾" supply lines.  Supply tank has a water/debris sump with a drain and Racor water sensor connected to an alarm in the pilothouse, creating the first line of defense against contaminated fuel.  As the lowest point in the fuel system, the supply tank provides a concentrated pick-up point for maximum usable fuel.  
  • Fuel transfer system draws from the bottom of each storage tank.  System uses a Walbro fuel pump to move fuel from tank to tank, or a tank back to itself, through a Racor 900 fuel transfer filter.  
  • The wing engine tank is only filled via the fuel transfer system, ensuring that all the fuel in it is clean.  Fuel to the wing engine is filtered through a Racor filter again in the supply line from the tank to the engine.
  • Reverso oil change system plumbed to main engine, generator and wing engine
  • Side Power 24-volt 10.7 HP bow and stern thrusters with controls in pilothouse, on flybridge and at cockpit control station

  • Central vacuum system (mounted in lazarette) 


The engine room is insulated with 2" foil faced leaded foam, covered with aluminum perforated plate.

The maintenance strakes contoured into the hull underbody allows a flatter main engine shaft angle for propeller efficiency as well as increased space in the engine room to walk around the engine.

There is easy access to all systems in the engine room.  The Lugger wing engine is to port and the Northern-Lights generator is to starboard.  

There is a fresh water spigot in the engine room.

A stainless-steel railing around the engine provides security and supports a custom sliding tool tray secured to it along with a three-drawer tool box.  


The lazarette is a large storage and machinery area accessible by a deck hatch in the cockpit and a door at the rear of the engine room. Cupboards and shelves port and starboard offer huge storage potential.

The lazarette also houses the ASEA 12Kw voltage converter, the 5kW inverter, the water maker, the crane hydraulic pump and the central vacuum cleaner.



The onboard system is electrical system is 230VAC at 50Hz. With the ASEA 12Kw converter the vessel can be powered from any shower power voltage and at frequencies or either 50 or 60 Hz making it a truly international vessel.
