Tanglewood is a superbly equipped and impeccably maintained Nordhavn 60. She comes to the market as her owner focuses on the construction of a new, larger Nordhavn. She will amaze both inside and out.
Whether your cruising plans include the high latitudes, Europe, Asia, or the South Pacific, Tanglewood will serve you well. She is equipped with an Olympia diesel heat system, four zones of Dometic air-conditioning, and an electrical system configured to operate in 50 or 60hz environments, and variable voltages. Also significant for cruising destinations warm and cold; all openings including doors, are fitted with insect screens.
Not to be overlooked is Tanglewood’s ease of handling. With her full ABT hydraulic system and its powerful, no-timeout thrusters, maneuvering in breezy conditions and tight spaces is an easy task for a couple.
Tanglewood’s layout is one of the most popular in Nordhavn’s history. One reason is that the main living areas are nearly on the same level from aft all the way forward through the interior. Passing from aft forward though the salon takes you to two shallow steps through the inboard edge of the galley to the master stateroom. Passing forward through the master stateroom and up two shallow steps takes you into the guest stateroom. If the master stateroom is occupied, access to the guest stateroom is up through the pilothouse down to a landing between the master and guest staterooms.
Among her attributes are a well-developed and integrated Maretron monitoring system, Furuno FAR radar, dual auto-pilots, and other redundant electronic systems, many in the commercial class. The owner’s technical acumen, boating background and high standards for equipment installation, have allowed him to build a stable and tremendously useful monitoring system that includes remote functions as well.
To add to the allure of this wonderful boat is the degree of documentation included. The owner’s unique capabilities and self-described obsessive-compulsive tendencies have resulted in the creation of the most detailed and up-to-date systems manuals, diagrams, and maintenance logs this broker has ever seen. They will ease the transition and enhance the enjoyment for any new owners.
Tanglewood is currently cruising in Mexico, scheduled for arrival in Seattle, May of 2018, unless sold prior.
Entering from the cockpit through the aft salon door, the salon has an L-shaped dinette to port and two Ekornes reclining chairs to starboard. There is bound edge carpet with integral anti-skid back over the teak and spruce cabin sole. Natural light enters through five side windows and two aft windows, including one in the upper section of the Dutch door.
The salon joins that galley at its forward end. As such, there is a clear visual connection between the salon and galley for easy socializing, and the space will accommodate two cooks. The galley includes all of the appliances for efficient meal preparation, and along with the chest freezer in the utility room, enough cold storage for extended cruising. The light, dominantly white, Vermont style salt and pepper granite counter tops create a bright feeling to the galley.
There are two specially designed chairs well-suited for seating at the counter or the salon dinette table.
A few short steps forward of the salon and through the galley is the entrance to the large master cabin. The bed is longer and wider than standard in the Nordhavn 60. There are night stands with drawer storage forward and aft of the head of the bed. There are two more banks of drawers forward in the cabin totaling six, plus two large hanging lockers. There is a dressing mirror in the alcove above the four drawer bank.
Beneath the bed there are additional drawers, plus additional organized storage space for the deadlights (stainless steel interior covers) for the portlights.
Light and ventilation are provided by the larger, optional, rectangular ports with screens located in the alcove above the bed.
The cabin sole is teak and spruce and includes hatches for easy access to the water tank inspection port and monitoring components below.
Although there is not a TV in the master, there is wiring for it behind the inboard longitudinal bulkhead, which would be the logical mounting surface for it.
Fore and aft entry door and head doorjambs have rubber gasketing to eliminate noise and produce an even quieter interior. Bulkheads are insulated between the stateroom. In fact, there are significant sound attenuation measures from the engine room through the interior to ensure that long passages remain comfortable over extended periods.
Master Stateroom Features
The master head is outboard to starboard of the master cabin. The sole and counter top are light, salt and pepper Vermont style granite for pleasant reflective light inside. The head is a Tecma fresh water flush. The advantage of the Tecma head is that they are generally quiet and each unit has its own macerator, and each is an independent system. Waste is macerated going into the black water tank and not while being discharged.
The shower stall is behind a glass door and is large, also with a granite pan. The shower stall includes two Euro style shower fixtures and a seat. There is an opening port in the shower, as well as an extractor fan for active ventilation.
Above the granite-topped vanity are two large mirrored doors opening to a large locker behind. There are make-up lights on each side of the mirror.
Master Head Features
Further forward from the master stateroom is the versatile guest stateroom and guest head. A longitudinal bulkhead with one hinged and one pocket door join to divide the space generally along the centerline, separating sleeping space to port from desk and work space to starboard. In addition there is access to the forward head while the sleeping space is occupied and the cabin divided.
There is also access to the forward bilge machinery space outside of the sleeping space.
There is a separate head access door from the sleeping space as well, to allow crew members from the pilothouse “captain’s cabin” access to the shower in the guest head.
Guest Stateroom Features
Forward Machinery Space
There is a hatch in the sole of the guest stateroom for access to the forward machinery space below. The pressure fresh water system, including the water heater, pump and distribution manifold are all located there. Additionally, the Spectra water maker, and its media pre-filter are also located there. There is easy maintenance access to all of the systems. Manual back-up pumps for the gray and black water systems are also mounted in the space.
Forward of the guest stateroom is the guest head accessible from each side of the divided forward cabin. It has a Tecma head, shower stall, and granite topped vanity with mirror above.
Guest Head Features
The pilothouse is the center of operations of course, but it also becomes a gathering space as well as an accommodation for off-watch crew. It includes a day head and sleeping cabin divided from the operation space. Central to operations is an adjustable Stidd “admiral” helm chair facing the upper and lower instrument consoles and the various controls and displays mounted there.
The forward raked windscreens and the black headliner both reduce glare from electronics displays while night running. The windscreen glass thickness and panel size is calculated to resist wave-loading.
Given the capability of the Nordhavn 60 to make extended passages over many days, safe operation and crew rest are essential. As such, the pilothouse is effectively isolated from activity in the galley, and sleeping cabins are effectively isolated from the pilothouse.
Just aft of the helm chair, is a dinette table and settee, with comfortable seating for 5 to 6. The height of the settee provides good sightlines through all of the pilothouse windows.
The cabin sole is also covered with a bound-edge, anti-skid backed carpet with matching mats at the port and starboard entry doors.
The upper and lower instrument display panels are angled to optimize instrument legibility from the operator’s position, while they are also visible to the rest of the crew. In addition, the overhead panel is hinged at its bottom edge, and fastened with thumb screws at its top for easy and manageable access behind the upper panel for maintenance. This well thought-out measure makes a potentially awkward job quite manageable without risk to personnel or equipment.
There are Dutch doors on port and starboard sides of the pilothouse. Each door has a Phantom screen installed in a custom built valence.
Angled and to starboard in the pilothouse is the main electrical distribution panel. It is protected from accidental contact with the systems breakers by hinged plexiglas panels. The panels themselves are another example of thoughtful planning. Critical systems breakers are protected with switch covers, and the panel functions have been increased to include additional 220-volt inverter service circuits and more 12-volt service functions than the standard panel. Breaker panels themselves open easily to expose a very neat, labeled wiring scheme behind them.
To port and behind a locker door, the KVH receiver and two mini-Macs are neatly mounted on a pull-out shelf. Everything about this pilothouse illustrates the careful planning, considerable knowledge and skill of the owner.
As with the other interior spaces, the pilothouse is an individual zone for both heating and air-conditioning.
Forward of the salon and to starboard are the steps down to the utility room and engine room. The utility room includes the clothes washer and dryer, a GE chest freezer, and storage lockers, and the entrance to the engine room.
There is a lifting stainless steel top over the chest freezer, which functions well as a work bench or laundry folding table.
Utility Room Features
The entrance to the engine room is in the utility room. The first impression of the engine room is its size and the access that it affords to all of the systems within it, and also to the lazarette through the aft engine room door.
With nearly full standing headroom, the engine room is easy to move through fore and aft. Movement around the main engine, wing engine and generator is easy. Access to critical functions related to the operation of the boat while underway, including fuel management and mechanical inspections are all easy to perform.
The owner has modified the engine room ventilation system by increasing the size of the exhaust fans, and relocated three of them up in the stack. The result is that much more air is moved through the engine room, and the heated air directed upward through the stack vault, resulting in a cooler space even when running in warmer climates.
Engine Room Features
The lazarette volume matches the aft cockpit in its beam and length, providing excellent access to the systems and components installed therein, such as steering, air-conditioning compressors, batteries, Glendinning cord retriever bucket, DC high current buss locker, inverters, and auxiliary battery charger. With all of those systems there remains lots of volume for spare fluids, fishing and diving gear, deck furniture, tools and more.
DECK AND EQUIPMENT
General Layout – from forward aft
Dual anchor rollers extend over the stemhead. The 175 lb. Manson Supreme anchor is mounted in the starboard anchor roller, which has been fitted with a grease fitting, and has had the channel in it machined to match the thickness of the anchor shank. A second roller installed at the top of the channel captures the upper edge of the anchor shank, securing it against rocking in heavier conditions. Just below the roller channel is a fixed nozzle directing a high volume stream of water from the
180 gpm hydraulic wash pump at the chain and anchor during retrieval. Any debris that may come on deck with the anchor and chain is captured in the ground tackle area on deck, and will drain to the waterline.
Aft of the anchor rollers a Maxwell 3500 hydraulic windlass is mounted on the ground tackle platform separated from the foredeck by a low bulwark. The Maxwell windlass is at least adequately sized for the type of use that an expedition trawler is apt to experience.
The foredeck is accessible from the starboard side deck or the Portuguese bridge. The starboard side deck allows crew members to move securely fore and aft.
The view from the flybridge is commanding. It is an advantageous position for entering or leaving an unfamiliar harbor, narrow passage through rocks or coral, and also for lounging at sunset. Essential functions for operating the boat are all there. In addition, there are two comfortable Stidd helm chairs – a significant upgrade over the standard - that can swivel around to the dinette table too.
The first element in creating a reliable, efficient single main engine propulsion system is engine selection. For that reason, Nordhavn often selects John Deere engines. They have a long history in commercial, as well as cruising boat applications, and a long history with Nordhavn. For a trawler style yacht application they can be used at horsepower ratings that are at the lower end of the range of ratings that these engine blocks are offered with (de-rated). Because of their various applications, including agricultural equipment, and over-road vehicles, replacement parts availability is very good worldwide.
A second element contributing to reliability is cooling the engine. The main engine is cooled by running the closed cooling system fluid through a keel cooler mounted in a recess on the outside of the hull. This keel cooling configuration is most often found on commercial boats. The cooler itself is analogous to a radiator, except immersed in water, and eliminates the raw water pump required to circulate seawater through a heat exchanger onboard the engine. One of several benefits is that the rubber impeller is completely eliminated, along with the attendant engine shutdowns due to its failure. Because raw water is not pulled in for cooling, neither is debris, eelgrass, plastic bags, or jellyfish.
Since raw cooling water is not mixed with the exhaust, the stack exhausts engine gas high above the deck into moving air, so it is not pulled back into the cabin by the “station wagon” effect. The aft salon door can be left open even when running downwind without pulling fumes into the living spaces.
A third element is a reliable and versatile fuel system, described in detail below the “Fuel System” heading.
The Nordhavn wing engine installation is a separate, dedicated propulsion system with its own shaft and propeller. If a main engine shutdown were to occur due to fouling of the main propeller, cross-linking an auxiliary power source to the main engine shaft would be rendered useless.
The generator is located to port and aft in the engine room. It has its own sound shield, so the combination if its sound shield and the extensive sound insulation measures in the engine room and salon sole, means the sound level while running it is comfortable in the boat’s interior. Since Tanglewood is fitted with the ABT “STAR” system (Stabilization At Rest), the generator is fitted with a PTO driving a hydraulic pump to both, operate the stabilizer fins while anchored, and also to supplement the hydraulic pressure from the main engine hydraulic pump for full system power to run both thrusters at full power, or a combination of thrusters, windlass and anchor wash pump.
Full ABT Hydraulic System, including Stabilization at Rest (STAR)
The advantages of the full hydraulic system on the Nordhavn 60 are several. First, the thrusters are very powerful, and can be used continuously without a thermal time out, making them very effective in sustained crosswind situations. There are controls in the pilothouse, port and starboard wing control stations on the Portuguese bridge, and also in the aft control station in the cockpit. The control levers are set to remain in the position that they are left in, so they can be used to “pin” the boat against the dock for tying up.
The system also includes two 180 gal./min pumps; one is for the anchor wash, and the other is a very effective emergency bilge pump located in the deep section of the bilge in the engine room.
With her air-conditioning and dedicated diesel heating system, Tanglewood is well equipped for cruising comfort at any latitude.
Diesel Heating System
The design of an efficient and effective diesel heat system for a boat with the interior volume of a Nordhavn 60 is important. A system that is undersized in capacity will run constantly, wearing out components prematurely, and not heating the spaces comfortably. While the HVAC system has heating capability, and can warm the interior nicely, it requires running a generator, and the air exhausts through soffits in the cabin that are near the overhead.
The diesel-fired Olympia boiler is rated at 105,000 Btu and uses a Becket burner system, used in many domestic systems throughout the US, making a replacement, if required, easy to source. The system runs primarily on DC power, except for its AC powered circulation pump, and the heat exhausts down low in the interior where it can rise. The system uses fluid lines heated and circulated through individually controlled fan units in various interior zones. Additionally, the fluid also flows through a second heat exchanger in the Torrid water heater for efficient water heating. All of the above makes the system efficient for use at anchor.
Tanglewood is also fitted with an engine “waste heat” exchanger that heats the fluid system while underway, eliminating the need to run the boiler unit at all.
Shore Power, Inverters and Charging Systems
Tanglewood’s electrical systems versatility is a product of her owner’s extensive background in electrical and electronic engineering and technology. The electrical system has been set up to operate in 50hz and 60hz environments, low voltage shore power (eg. 208-volt often found in Northwest Marinas), and with the ability to provide 240-volt service from the inverters while underway for washer, dryer and oven, without running the generator.
Power generation at anchor has also been accommodated with a 750w array of solar panels on the flybridge hardtop.
There are four fiberglass storage tanks and two aluminum supply tanks in the system for a total of 2,250 gals. Fuel is carried or distributed via Aeroquip hose and fittings.
Tanglewood’s owner has taken full advantage of the versatility of the Nordhavn gravity feed fuel system that allows either free flow of fuel to the supply tank, or pre-filtering fuel to the supply tank.
The supply tank (sometimes referred to as a “day” tank) functions as a tubular supply manifold would on most boats, but has multiple functions over a standard manifold. It is the lowest, most concentrated, point in the fuel system, and has a sump at its bottom with a drain valve and water sensor connected to an alarm in the pilothouse. If water were to accumulate in the fuel system, the most likely place to detect and remove it would be at the supply tank. The supply tank includes supply valves for the main engine and generator.
On Tanglewood, the fuel supply method has been to actively transfer fuel through the fuel transfer system that includes a transfer pump and Racor 1000 transfer filter. Since the supply tank has a 30 gal. capacity, combining it with the two forward storage tanks gives the effective “supply tank” a capacity of gals. Tanglewood also has an upgraded, higher capacity fuel transfer pump and transfer filter.
Fuel System Features
Oil Change System
Black Water System
The black water (waste) system consists of the three heads that are plumbed to discharge overboard, where permitted, or directed to the 120 gal. black water holding tank. The contents of the black water may then be pumped out by dockside or mobile pumping facility, through the deck, or through the hull, where permitted, using either the electric or manual pump.
Black Water System Components
Gray Water System
The gray water system is designed to discharge or temporarily store used fresh water. The system consists of (prox.) 100 gal. storage tank, level indicator, manual discharge pump and electric discharge pump. The tank receives water from shower, wash basins, laundry, and air-conditioning condensate drains. The galley sink drain is fitted with a Y-valve to allow it to discharge directly overboard, or to the storage tank.
Gray Water System Components
The electronics complement on Tanglewood is impressive by any measure. The systems have been set up with the deliberate involvement of the owner, who is eminently qualified to employ the technology. The objective has been to create stable, reliable systems of unusual accuracy, including careful calibration of sensors and sending units in the Maretron monitoring system, but also simplicity and minimal integration of the navigation systems. The components, including the Furuno FAR radar, as an example, are essentially in the commercial class.
Systems components and their model and serial numbers are all included with the “as-built” documentation that will inure to the new owner.
Maretron Vessel Monitoring System
The Maretron system provides an extraordinary amount of visual information “at a glance”. It can be placed into modes for at-anchor, underway, or moored. Far from a “gadget”, this is a powerful, very useful monitoring system.
Video Monitoring System
The boat is turn-key and ready to get underway this season.
