The Boat


The Boat 


A Brief History 

Tivoli was constructed in 1998-99 and commissioned on the East coast for her original owners, Bill and Barbara Hakos.  She was kept on Chesapeake Bay during summers and traveled to West Florida during the winters so she had relatively few hours on the engines and was in great shape when we purchased her in April, 2011.  We brought her down the East coast to Key West and up the West coast  of Florida to Tampa.  We hired Captain Bernie Francis to bring her across the Gulf and up the Tenn-Tom to Aqua Yacht Harbor on Pickwick Lake so that she would be close to our home in Memphis.  For the past 3 years we have worked nearly every spare moment refitting and updating the boat. The engines had few hours and are in great shape but nearly every other major system on the boat has received attention.  We’ve updated the cooktop, microwave, and disposal in the galley, new ultraleather upholstery throughout the boat, replaced the ceiling panel upholstery, replaced salon chairs, stereo system, new washer/dryer, water pump and filtration system, replaced the tender, updated all the electronics in the pilothouse (radars, chart plotters, GPSs, AIS, VHF, FLIR, side-scan sonar, cameras, etc.) new stainless muffler, batteries, inverter, monitoring systems,  alternator, A/C unit in pilothouse, Stidd chair, teak wheel, stainless muffler, Rocna anchor, life raft, first aid supplies,EPIRB, PLBs, life vests, AED, new Steelhead davit, Spectra watermaker, etc. etc.  This is our new home and we wanted her safe, well-equipped for passagemaking and comfortable. I believe we have succeeded.


Tivoli Gardens in Copenhagen was the inspiration for the builders and first owners of this boat.  We decided to keep the name thinking it is short and sweet and should work well in radio communications.  Of course, it is still commonly mispronounced Tiv-oooh-lee….nothing is simple it seems.

Boat Overview

Pacific Asian Enterprises (PAE) intended to built a solid successor to the venerable 46 Nordhavn but with a more spacious and modern design and with a faster turn of speed.  They succeeded in that Tivoli can idle along for days on end burning only 3 gallons of diesel/hour while achieving 7 knots of speed (she carries a total of 1320 gallons).  Bump up the fuel burn to 9 gallons/hour and she will hit a maximum of 10 knots.  Doesn’t seem like much when you consider a riding lawnmower can easily outpace us, but the extra speed makes a big difference in distance covered per day and comes in handy if needed to outrun weather, reach port at optimal tide, etc.  It is a nice feature to have and is made possible by using a larger Lugger engine, the 300 HP turbo-charged after-cooled L6108A.  This 6-cylinder beast is the epitome of reliability; we’ve heard they will run 30,000 hours before overhaul if maintained properly.  Since the boat only has 2500 hours on it and one can circle the globe in a few thousand hours we don’t anticipate needing a major overhaul anytime soon (knock on wood!).  The engine is keel cooled eliminating several points of failure (water pumps, impellors, etc.).  The boat also differed from the 46 in having a bulbous bow.  Tank testing suggested this would improve the hull’s efficiency and the experience of many 50 owners suggest that is the case.  Of course there are detractors as this design feature can have an annoying wave slap under certain conditions but we have yet to be annoyed.  Critical to comfort aboard while underway is the hydraulic NAIAD stabilizer system.  The fins mounted on either side of the hull rotate under gyroscopic control and serve to keep the boat flat in seas; i.e. dampen roll from side to side.  These systems are remarkably efficient and really do work well.  The boat’s main prop is shown below; there is also a “wing” or “get home” engine with its own drive shaft and folding prop.  It can power the boat along a 4 knots or so in calm water and is a redundant propulsion system in the unlikely event the main Lugger needs to be shut down for any reason.  The boat has a full keel and a skeg-hung rudder offering protection to the running gear.

Outdoor Living Spaces (Foredeck, Boatdeck, Cockpit)

The exterior of Tivoli has several areas while underway or at anchor to manage the boat and to enjoy the surroundings.  They include the “foredeck” or bow of the boat, the “Boatdeck” or top aft of the boat, and the “cockpit” or aft end of the boat, and a starboard-side walkway.  The pilothouse roof also is home to various items of equipment.  Each has its functions and uses while underway, docking or anchoring.

The Foredeck

The boat is designed for offshore travel and has design features to accomodate heavy seas.  The foredeck is home to a storage locker for mooring lines, anchor snubber, water hose, and other paraphernalia.  It has two dorades that allow air and not water to enter the boat.  Most importantly, it is home to the anchor gear, a beefy Maxwell 3500 chain/rode windlass provides the muscle to deploy and retrieve our 125 lb. Rocna anchor along with up to 400 feet of 3/8′ galvanized chain.  A separate anchor can be stowed and deployed as well and a separate Fortress anchor is available if needed.  High stainless rails provide a secure platform for handling anchoring duties.  Further aft is the “Portugese bridge”.  This is a secure walkway about chest height that offers a very secure location to observe and pass from one side of the boat to the other; a gate in the Portugese bridge allows entry onto the foredeck.

The Boatdeck

The Boatdeck is home to the family car; out 12 foot Rigid Boats tender with a 40 hp Tohatsu outboard.  To launch the tender we have a Steelhead ES1000  electrohydraulic davit or crane.  The boatdeck is a nice place to deploy our folding deck chairs and watch the sunset with a glass of wine.  The Boatdeck is also the platform for the ‘stack”, this structure houses the dry exhaust stack and stainless muffler and also serves as a place to mount electronics such as radar, satelite TV, a host of antennae (GPS, WiFi booster, Cell Booster, AIS, etc.), wind instrument, lights, hailer horn, search lights, etc.  The pilothouse roof is home to our Winslow 6-person life raft in a cannister and a Seaview mount with a 4G Broadband radar antenna, a FLIR infrared camera, Maretron weather sensor, and Iridium satelite phone antenna.

The Cockpit

The Cockpit at the aft end of the boat provides access to the main entry into the saloon, access to the swim platform, and a ladder providing access to the boat deck. It also has two storage lockers and a large hatch providing access to the lazarette.   It is also a convenient place to grill fish on the barbee and to lounge in deck chairs while watching the sunset

The Accomodations

Living aboard Tivoli is not unlike living in a tiny New York apartment in terms of space.  In spite of being 50 feet long and 16 feet wide with 3 levelsshe is small in comparison to most homes.  The advantage, of course, is we can move our home to any coastal location on the planet.  Perhaps the best way to familiarize yourself with Tivoli is to read the descriptions of each of the living and working spaces aboard


The saloon is the “living room” on the boat; it contains comfy chairs and settee, entertainment equipment, and lots of storage for the usual range of goodies needed for long-term cruising.  It is open to the galley and the combined spaces create an inviting and fairly large living space that is comfortable at anchor or underway.

Pilothouse (PH)

The PH is the center of all operations aboard.  It house the helm; all navigation electronics, power management for 240 VAC, 120 VAC, 24 VDC, and 12 VDC systems, Controls for each of the three engines aboard (main, wing and genset); safety gear; and communications gear.  The pilothouse also houses a large L-shaped settee and table that can accomodate up to 6 guests to enjoy the passage, dinner, cocktails, etc.

Sleeping quarters

Tivoli has two staterooms; the master stateroom (MSR) is under the pilot house and just forward of the engine room.  This position was chosen as this location should experience the least motion when underway in seas.  This stateroom has a center walk-around queen size bed and ample drawer and hanging lockers for storage of clothes, bedding, etc.  The guest stateroom (GSR) is in the forward end or bow of the boat also has a Queen size bed on the port side with ample drawers and lockers for storage.


Each stateroom has its own ensuite bathroom (head) including toilet, sink, shower and ample storage compartments.  The waste is directed to an 80 gallon black water holding tank for pump out at an appropriate facility.  Most marinas offer such pump out services and many locations have boats equipped to travel to your location to empty your holding tanks as well.  Regulations do allow discharge directly into the ocean while at sea.  The Captain will handle all pump outs.


The kitchen (galley) is equal to that in any land based home.  It has ample Corian counter space, a double sink, dishwasher, trash compactor, microwave/convection oven, Wolf induction cooktop, refrigerator/freezer, icemaker, and disposal.  Ample storage is provided for food, beverages etc.

Engine Room

The engine room (ER) is home to three diesel engines; the main propulsion for the boat is a Lugger 250 hp diesel engine.  This engine was built for the Alaskan fishing industry and is known for its longevity – 30,000 hours before overhaul is not uncommon.  Tivoli has ~2500 hours at the time of this writing.  It is also remarkably fuel efficient; burning approximately 2.8 gal/hour at 7 knots.  The Northern Lights generator (genset) is located on the starboard side of the ER.  In the event the main engine needs to be shut down the “wing engine”; a Yanmar 24 hp engine with its own drive shaft and folding prop can be started and will move the boat along at about 4 knots in calm seas.  The ER is flanked by two of the four fuel tanks; each of these primary tanks holds 550 gal of diesel.  Two additional fuel tanks (125 gal each) are located in the lazarette.  The ER houses fuel filtration and fuel transfer functions; numerous pumps (fresh water, sea water, bilge, stabilizer cooling, etc.).  Finally, the NAIAD hydraulic stabilizers are mounted port and starboard with the gyro unit mounted on the port side.  These units move “fins” mounted externally on both sides of the boat to keep the boat level in seas.  Without the steadying force of sails, power cruisers such as this need active (or passive) stabilization methods to keep the ride comfortable.



The lazarette refers to the aft portion of the boat below decks; the seating area above the lazarette is referred to as the cockpit.  The “laz” is home to the house battery bank, inverter, Glendinning power cord retrieval system, and all 4 A/C compressors.  It also seems to collect a huge amount of “stuff” that one seems to need; folding chairs, awnings, tools, etc.
The boat was originally fitted with Asko washer and dryer.  These are located in the stairwell leading to the staterooms.  A simple part failure on the dryer led to replacement of both units (long story).  The old models had to be disassembled to remove them from the boat.  Clearly, the boat had been constructed around the washer/dryer.  Unfortunately, Asko increased the height of their 2014 models by 1 inch so they would not fit. We selected separate Splendide units, a 110V washer and 220V dryer.  Some teak trim had to be temporarily removed to accomodate the washer but the dryer fit in the available space perfectly.  As it turns out, all holding tank antisiphon and pumpout hoses are located behind the washer and dryer so we replaced these while the compartments were empty.

The Systems and Resources Aboard
Propulsion System
The main propulsion engine is the venerable Lugger L6108A2.2.  It is a 300 HP turbocharged and aftercooled diesel engine with an expected time before major overhaul of approximately 30,000 hours.  She is designed to run at wide open throttle 24×7; a continuous duty engine.  Many other makers of trawlers do not equip their boats with continuous duty engines.  This, in my view, is critical to long passage-making. 
Fuel System
Tivoli carries 1430 gallons of diesel fuel in 4 tanks.  Two saddle tanks of 550 gallons flank the engine in the engine room.  Two additional tanks of 125 gallons are located in the lazarette.  A valve manifold system allows the transfer of fuel to/from any tank to any other.  The main tanks have sight gauges that allow easy assessment of remaining fuel.  The aft tanks do not have sight gauges so typically the fuel is simply transferred from the aft tanks when needed.  A fuel pump is used to transfer or polish fuel through a Racor 900 filter.  Fuel fed to all three engines is filtered through 30 micron Racor filters, as well as via on-engine 10 micron filters.  Fule consumption is also measured using Maretron fuel flow monitors.  A DSP150 display in the pilothouse provides gal./hr, total gallons consumed since reset, and nautical miles per gallon.  One can adjust engine RPM to achieve a particular MPG figure to ensure sufficient fuel remains for the voyage.
Lube Oil System

Oil in all three engines (main, genset, wing) can be changed using a Groco oil exchange pump.  Oil is simply pumped into empty carboys at the flip of a switch.  One can reverse the flow of the pump and pump fresh oil back into an engine but we prefer to simpy add to the engine directly.

Fresh Water System

We carry 300 gallons of fresh water in 4 tanks each independently accessed via a distribution manifold.  The volume remaining is displayed on a Watercounter display in the pilothouse.  Water from the tanks is pumped throughout the boat using a 110V Headhunter Mach5 pump.  Multiple filtration units are used to remove sediment, chlorine taste, etc.  A Spectra Newport MKII 400 gallon per day 12 VDC watermaker is fitted in the lengine room and allows us to desalinate sea water using reverse osmosis filtration.   The eliminates the need to purchase water in arid islands and provides an inexhaustable supply on passage.

Toilet/Holding Tank System
Both heads are equipped with new Atlantes electric heads.  These empty into a 50 gallon holding tank.  The tank is typically emptied using the pumpout fitting on the starboard deck.  At sea a diaphram pump can be used to pump the contents overboard.  A manual diaphram pump is also fitted should the primary pump fail.  A Hart monitor is in place to measure the level in the holding tank.  It is very accurate and works quite well.

Shower Drains/Sump System
Both showers are fitted with Whale Gulper 320 diaphram pumps; shower water is pumped directly overboard.
Bilge Pump System
The bilge is fitted with two electric Jabsco diaphram bilge pumps; a low water pump and a high water pump.   A high water alarm is also fitted.  A third manual bronze Edson diaphram pump is fitted should the electrics fail.  Finally, an 8000 gallon per minute pump is availabe with 30 feet of 3 inch hose.
Steering System
The boat is equipped with Hynautic hydraulic steering..  A teak wheel in the pilothouse turns the rudder manually.  A Simrad AP70 autopilot and AC70 Course Computer controls an electric Accu-steer hydraulic pump in the lazarette that turns the rudder stock.  A backup RPU300 hydraulic pump is also fitted so that, in the event of failure of the primary pump the flip of a swith will activate the standby pump.
Stabilizer System
NAIAD hydraulic stabilizers are fitted.  This system was upgraded to the 452 model by replacing the original hydraulic actuators with 1″ and replacing the 3 GPM pump with a 5 GPM pump.  The fins are 6 sq. ft.

Air Conditioning & Heating

Tivoli can be kept at a comfortable temperature in nearly all conditions.  She is exceedingly well built and insulated and carries 4 reverse cycle A/C units in the lazarette for a total of 65,000 btu’s of cooling/heating capacity.  Digital thermostats in the salon, MSR, GSR, and pilothouse control the temperatures in each of these locations.  Opening portals and windows are located in every living space as well.

Engine Room Ventilation System

Fire Suppression System

Automatic fire suppression system in the engine room (ER) shuts down engines and blowers and discharges a large halon extinguisher in the event of a fire.  This system can also be manually activated from the helm

Electrical Generation System

The boat is equipped with 240VAC, 120VAC, 24VDC, and 12VDC electrical systems with corresponding distribution panels in the pilot house.  240VAC and 120VAC can be obtained either via shorepower while at the dock or underway or at anchor using our 12 KVA Northern Lights generator.  This unit produces 240 VAC power sufficient to operate all equipment on board.  If we don’t require A/C or other heavy load equipment we run on battery power alone with a Magnum 2800W inverter/charger providing 110V power for general small appliance use.  12VDC power is provided by a “house” battery battery bank consisting of 6 8D lead-acid batteries mounted in enclosures in the aft portion of the boat (Lazzarette).  With 225 Ah capacity each we have a total of 1350 Amp hours.  Since we recharge at 50-60% capacity approximately 675 Amp hours are available for use.  This would typically power all systems aboard (@ 30Amps) for 22 hours before it is necessary to start the generator to recharge the batteries.  These are charged using the 130 Amp charger built into the Magnum inverter using power from either shorepower or Northern Lights generator or underway using the 160 Amp alternator mounted on the main engine.

A separate Starter battery bank is fitted consisting of 2 8D AGM batteries  mounted under floorboards in the MSR.  These power the main engine (Lugger) starter, the bow thruster, the anchor windlass, and two radial Delta-T intake and exhaust fans in the engine room.  This bank is kept fully charged using a 24 VDC alternator mounted on the main engine or a MasterVolt battery charger mounted in the ER.
Electrical Distribution System

Management of these systems is done using circuit breaker panels for each mounted in the pilothouse.  Blue Seas digital voltage and current monitors display status and current utilization.  In addition, Balmar SmartGauge monitors are mounted in the pilothoiuse to monitor state-of-charge and voltage on both 12 VDC and 24 VDC battery banks.

Accessory Systems

If the surrounding beauty is not sufficient to entertain us we have a variety of options.  We fitted a KVH M1 satellite dish and two receivers for the salon and master stateroom.  This provides access to DirectTV channels anywhere in the US.  A Blu-ray DVD player is available for movies.  We also replaced the original stereo system with a Bose surround-sound unit including an amp, cockpit speakers, and a remote control allowing us to watch TV inside while listening to audio in the cockpit.  Audio sources include a SiriusXM receiver and an iPod dock with 12,000+ tunes.  A separate SiriusXM receiver is integrated into the Simrad electronics in the pilothouse providing both audio and weather data that can be overlayed onto our navigation charts.
