Expedition M/Y “Northern Sun”


Northern Sun has been transformed from a fisheries research vessel into a luxurious long range expedition yacht.  She was taken back to bare steel inside and out and completely rebuilt with new lagging, wiring, plumbing, electronics, generators, air-condition, cabinetry, furnishings, bathrooms, galley, cranes, tenders, teak decks, fully faired and painted in Awlgrip.

Her teak laid Sun Deck is completely private above the Bridge.  It boasts a 4 man Jacuzzi, an abundance of sun lounging areas, a bar fridge, ice maker and sink and her deck furniture stores neatly inside the funnel at the rear of the deck.  New sail awnings offer shade from the sun.  A day head was installed in stbd. side of The Mast in 2015.

Easy stairs on the port side lead down to the Bridge Deck which has a beautiful wide Portuguese style teak deck passing in front of the bridge and leading aft port side and stbd to the Boat/Heli Deck aft.  Life rafts stow neatly outboard and there are 2 recessed fire hydrants outside the bridge wing doors.  The 2 wing controls are housed in separate boxes which close flush into the bulwark when not in use. 

The Boat/Heli Deck is teak laid and has stainless steel safety rails all around.  A 2 tonnes Stromme crane is mounted centrally aft of the funnel and can lower either tender port side or stbd into the water. Again the funnel is cleverly used to house the crane hydraulic pack and radio batteries.

Access to the Bridge is from port and stbd wing doors or from an internal corridor.  The navigation equipment has been sensibly thought out and positioned by her very experienced captain.  A full list of equipment is detailed under bridge equipment.  The windscreens have a negative angle to reduce glare, and two have all clear screens for inclement weather.  The all around visibility is excellent.  An easy bench seat on port side with small coffee table allows guests and owner to enjoy the view whilst cruising.  There is a chart table with drawers on port side and a good sized worktop on the stbd side.  As well as the latest navigation equipment, there is also a flag locker with full set of signal flags. A Waeco drinks fridge is neatly located on the stbd aft wall.

Leading aft from the Bridge on the stbd side, the corridor takes you first to a fully equipped Radio Room and then to a generously sized Captain’s Cabin, equipped with television, telephone, drinks fridge and Ensuite Bathroom.

The Corridor then leads further aft to stairs down to the Main Deck.  At the top of the stairs is a fire control panel, a locker with remote fuel shut off pulls and cables, a PABX telephone control box and the Nera Fleet 77 control box.

At the bottom of the stairs is a Pantry giving a three-way access to the stbd Side Deck, inboard to the Crew Stairway or aft into the Salon.  The Pantry has a U-Line ice maker, American Home fridge, hand basin and lockers.

Concentrating on the exterior, the Forward Working Main Deck is painted non slip white.  There is a duel hydraulic windlass with 2 x 1500 lbs anchors and access hatch to the chain lockers.  A large hydraulically raised hatch gives access to the garage where the crew tender or jet skis can be stowed out of the way using the on deck Bezensoni crane.  A smaller hatch gives crew access to the garage from the deck and from here a separate corridor leads aft to the Crew Mess or forward to the Bosun’s Locker.  There is a separate compartment for the bowthruster hydraulic pack, emergency diesel driven bilge or fire pump and hydraulic windlass power pack.

Back on deck, teak decks lead in front of the Salon to a beautiful forward facing recessed seating area with coffee tables and sun awnings.  This makes an ideal area for evening cocktails or relaxing whilst underway. Moving aft down the port or starboard side decks are two reception doors at mid ships giving access to the salon with well located side boarding ladders mounted flush into the bulwarks.  Fire hydrants and life rings are nicely recessed into the bulwarks and superstructure and there is a hot and cold shower on the stbd. side to rinse off after a swim.

Moving further aft, down the wide Side Decks with beautifully varnished caprails, you reach the Aft Deck Area with fitted seating and large varnished table for al fresco dining.  Either side of the seating, two impressive stairways join to lead down as one, to the teak laid Bathing Platform, making a very practical and attractive transom for stern to mooring.  A hydraulic passerelle stows neatly inside on the stbd side, whilst the hot and cold shower stows away on the port side.

The Main Deck interior has a full length Saloon giving fantastic visibility all around, with three clearly defined areas.  Forward is the Piano Salon with an excellent view ahead.  At mid ships is a plush Lounge Area with pop-up flat screen television and Bose Surround Home Theatre system.  There is a day toilet off to port and a wide corridor leading to the Aft Viewing Salon with panoramic views of the aft deck and beyond.  The floor is finished in a beautiful dark Nara wood and two Barrique wine fridges store your favourite wines.

The Main Deck has two separate stairwells to access the Owners and Guest Cabins.  From the Middle Lounge, a central stairwell leads down and forward to the Dining Room on the port side and Owners Study on the stbd side.  The dining table seats 10 in comfort and is well equipped to stow crockery and glassware.  The Study has an open plan style and has a comfy chair and foot stool for relaxing; with a separate writing desk and chair.

Moving forward on the stbd side, you enter the full-beam, very impressive Owners Cabin with king sized bed, sofa and separate vanity unit.  There are plenty of hanging lockers, a safe, flat screen television and Bose Surround speaker system.  The Ensuite Bathroom is huge, boasting a two person Jacuzzi and separate shower.

Moving aft from the Study, a corridor leads to a good sized Twin Guest Cabin with Ensuite Bathroom.

From the Dining Room, a door leads into a Pantry and further aft into the Galley.  The Pantry has a Fisher & Paykel fridge, U-Line ice maker, Barrique wine fridge, Miele dishwasher and sink.  The Galley is well equipped with Miele oven, steamer, plate warmer, 2 Viking 4-ring hobs and 2 Viking ovens, an industrial extractor fan, a Sub Zero fridge freezer and double sink unit with insinkerator.  There is also a large walk-in fridge and freezer outside the Galley in the Crew Corridor.

Moving further aft, down the Crew Corridor, is the Engine Room Control Room and, further aft, a door leads to the aft Guest Cabins.  These cabins can also be accessed by a Guest Stairwell on the port side near the Aft Viewing Salon.

The Aft Guest Cabins comprise of 4 guest cabins, 2 twin, 2 double, all with ensuite bathrooms.  New televisions, Blu Ray players, Bose speaker and I pod docking stations were fitted in 2015.  There is also a telephone intercom for each cabin.

Much consideration was given to guest and crew circulation to maintain maximum guest privacy.  Crew enter the Lower Deck Crew Mess and Cabins from the Galley Corridor or from the Bosun’s Locker forward.  The Crew Mess is well equipped with large table, Sharp TV, DVD player, Digital Multiplex recorder, Fisher & Paykel fridge, Whirlpool microwave, U-Line ice maker, Miele dishwasher, Furuno VHF, and camera monitor for the 4 security cameras.  Crew Cabins are well appointed with ensuite bathrooms per the layout plan.

The Laundry is aft of the Crew Mess and equipped with 3 Miele W2104 washers, 3 Miele T422C dryers, a Miele D815D roller ironing press and plenty of storage for linen.  Access to the stabilizer fin and hydraulic pack and frequency converter is from the Laundry.

The Engine Room is in superb condition.  The equipment has either been overhauled or renewed.  New equipment includes:  2 “FCI” water makers (1800 gallons/day each), 6 Cruisair air-conditioning compressors with Smart random selector on demand, Head Hunter toilet system, 2 x 170KW Tritex generator, on demand fresh water pumps, air compressor for engine starting system.  The work shop has a lathe, bench drill, grinder, work bench and vice, 2 hot water tanks, plenty of tools and is air-conditioned.  The entire area is a show piece.

A new dive locker was constructed in October 2012 in the port aft Lazarette with the installation of a new dive compressor, racks to stow dive bottles, BCDs and dive equipment.  There is also a new rack to stow fishing rods and reels.

2015 upgrade and improvements.  All aft guest cabins have been rebuilt on a floating fully insulated manner significantly reducing noise levels whilst cruising.  Radio equipment was been upgraded to operate the yacht commercially.  New pipework fitted in engine room.  New stainless steel fuel polishers fitted.  Aircon compressors overhauled.  Water makers overhauled.  Top sides repainted December 2015.  New Gym equipment and toys. 


Northern Sun is ready for a New Owner to take over, add their personal touches, provision the yacht and go worldwide cruising.  She is a very stable lady with long range capabilities.  The yacht has benefitted from her owner’s constant improvements, upgrades and refinements and spent money in the engineering department where other yachts fall flat.  At USD15,000,000, she represents excellent value for money.  Now upgraded to operate commercially and charter out at a weekly rate of USD140,000.
