Insurance

It is absolutely essential, that you obtain adequate insurance cover for the yacht and the equipment and for personal and third party liability.

If the yacht is intended for water skiing or other special uses, be sure to inform your insurance company in advance.

12.02.2010 Revision: - 4/114


I. Before You Start
1. About Your Owner’s Manual

This manual has been compiled to assist you to operate your yacht with safety and pleasure. It contains details about the yacht, the
equipment, the systems and information about the operation and maintenance.

If this is your first yacht or a new type of yacht you are not yet familiar with, for your own safety please ensure that you obtain handling
and operating experience before taking over the helm.

KEEP THIS MANUAL IN A SAFE PLACE AND HAND IT OVER TO THE NEW OWNER WHEN YOU SELL THE YACHT.

This manual is based on the standard specification of the MAZARIN 72. Every attempt has been made to provide accurate information.
For customised models there may be changes in placement and materials. Therefore some information, photos and drawings may not
apply specifically to your yacht. SMG reserves the right to modify the described specifications without prior notice in order to improve the
yacht.

 Sections marked with this open book symbol have further information in the user’s manual.

Warnings, cautions and dangers are marked with these symbols.

Disregard of these instructions my lead to personal injury or damage to equipment.

12.02.2010 Revision: - 5/114


2. Delivery

Your dealer is required to carry out a series of checks and inspections on the yacht. This is a very thorough commissioning of the yard
carried out by trained personnel of the dealer to ensure that your yacht is performing and functioning correctly.

The pre-delivery inspection certificate should be completed and stamped by your dealer and we would like you to sign this certificate to
confirm that you are fully satisfied with the service of your dealer as well as with your new yacht. This will then complete the SMG
documentation on your new yacht and validates the warranty.

Please ensure that your yacht, the engines and the generator are regularly serviced by appropriately trained personnel. In case of a
warranty claim or when you would like to resell the yacht you can then document that your MAZARIN Yacht has been well cared for.

Warning!
Do not shift too quickly from forwards to reverse. Stay in the neutral position until the yacht has lost most of the forward momentum and
only then shift to reverse. Never shift to reverse when the yacht is planning.

III. Running Instructions

12.02.2010 Revision: - 23/114


1. Instructions

An experienced operator should accompany a new yacht owner who lacks operation experience until he/she becomes familiar with the
controls. After learning the fundamental rules of manoeuvring, practice will perfect these fundamentals and make the operator adept in
handling the yacht.

Pre-start checks

Before starting the engines make sure that you inspect the engine room:

a) There is no fuel leakage.
b) There is no water leakage from the engine or hull.
c) There is no oil leakage.
d) The oil level is correct. Check the oil level with the dipstick.
e) Check cooling water level in the expansion tank.
f) Check that there is enough fuel on board for the planned voyage.

Instruct all passengers and crew on the workings of the yacht and where to find the life jackets, fire extinguishers etc.

Also inform them on everything you think important from a safety point of view. If something unexpected should happened on the voyage
it is often too late to explain to those on board how the safety equipment works.

Starting the engines

Danger!
12.02.2010 Revision: - 24/114


Failure to properly ventilate all areas of the yacht can result in a dangerous accumulation of carbon monoxide. Cabins and cockpit are to
be well ventilated at all times when the engines or the generator are running.

a) Check seacocks are open.
b) Switch on the main battery switches.
c) Turn on fuel taps.

After having ensured that the engines are ready for operation (i.e. all above mentioned tests and steps have been made) turn the ignition
key on the main deck helm station in position ON (horizontal)

Afterwards click with the track ball on the symbol START on the monitor. Pushing the COMMAND button on the lever will give you the
control at the respective helm station. After having ensured that no one is in the engine room you can now start the port and starboard
engines by pushing the corresponding START buttons one after the other. After starting the engines the corresponding operational
displays need to be monitored.

Running in

12.02.2010 Revision: - 25/114


A new engine must be run-in with special care during the first 20 hours of operation. Do not run the engines under full load during this
period. Oil consumption can be expected to be higher than normal during this period and so the engine oil level should be checked
frequently.

Maximum Engine Speed

Please refer to the engine handbook for exact information on the engines fitted in your yacht.

The following information is provided as a general guideline only.

During the running in period the engine speed should be restricted to approx. 300 RPM below maximum.

For extended periods of operation at cruising speed the recommended engine speed is 200 – 600 RPM below maximum.

If the yacht has been in the water for an extended period of time, the speed and the maximum engines RPM may drop as a result of weed
growth on the hull. Minimise this growth by painting the underwater hull with antifouling paint.

In areas of high algae, performance of the yacht can drop by 2-4 kn after a month. So it is very important to keep the hull clean.

Shutting down

12.02.2010 Revision: - 26/114


Before stopping the engines they should be allowed to idle for a minute or two with the control lever in neutral.

The MAN engines are stopped by pushing the STOP button on the flybridge helm station and or by turning the ignition keys on the OFF
position (vertical).

Afterwards the two main battery switches can be turned off.

It is advisable to check the engines and generator for leakages and to ensure that the bilge is dry after the engine room has cooled off.

Engine Room Ventilation

The engine room of the MAZARIN 72 has two large extractor fans located in the aft end. These are DC 24V.

The engines are commissioned under strict conditions at the factory, and cool air temperatures in the engine room are a critical
requirement for the warranty of the engines. Without these fans the temperature will increase to a point where the engines will lose
performance.

The temperature is controlled by a thermostat which should be set to 32° C. This thermostat control is located midships in the forward
engine room bulkhead.

Carbon Monoxide Fumes

12.02.2010 Revision: - 27/114


Warning !
Any blockage of hull exhaust by a seawall bulkhead or any other obstruction can cause an excessive accumulation of carbon monoxide in
the yacht’s interior.

Warning!
When tied to a dock or immediately alongside other vessels it must be ensured that no exhaust fumes of the other vessels accumulate in
the yacht’s interior.

Warning!
When running the engines or the generator at a slow speed or dead in the water, pay particular attention that the exhaust fumes do not
accumulate in the yacht’s interior due to wind conditions.

Yacht handling

12.02.2010 Revision: - 28/114


It is impossible to teach someone in two or three pages how to operate a boat at sea and manoeuvre it safely in the marina. Driving and
manoeuvring skills will come with practise at sea. Every time you go out on your yacht, you may experience different weather and sea
conditions and so it will take many miles at sea to become fully confident. Proficiency will only by achieved by practice.

Each owner has the responsibility to inform himself/herself on the respective legal rules and regulations before undertaking a voyage.

Needed are among others the following documents:

- Valid driving permit (Original)
- Proof of insurance (Original)
- Valid ship registration (e.g. flag certificate, ship’s register)

Leaving the Berth

12.02.2010 Revision: - 29/114


Every skipper will check that all equipment is stowed well and safely. All hatches and portholes must be closed. Keep the boat hook and
warps within easy reach. Ensure that the VHF is working and get a current weather report.

Caution!
When going out to sea, ensure that the safety equipment is on board with easy access. As skipper of the yacht you are responsible for the
crew and passengers on board. Ensure there are enough life jackets for all crew and passengers.

Once the engines are running smoothly remove all mooring lines. Take care that the lines do not become entangled in the propellers and
that nothing trails in the water.

Go slowly out of the harbour. Once free of the quay and other vessels, pull the fenders aboard and stow them in a place where they are
easily accessible.

Rough Weather Driving

Inform the coast guard when leaving on a voyage and of your expected time of return.

Even though MAZARIN Yachts are built to withstand bad weather conditions, an experienced skipper will first consider the welfare of his
passengers before taking to sea in bad weather.

Please do not venture into deteriorating weather conditions.

Consider your insurance clauses.

Avoid letting the boat ride parallel to the waves unless they are small swells. Extra high, unpleasant waves should be negotiated carefully.
Experienced skippers can successfully steer the yacht through heavy seas. The direct route is not always the best – beat like a sailer and
adapt the speed to the waves.

It must be remembered however, especially in rough weather, that all equipment und loose items are stowed away safely. All windows
and portholes must be securely closed.

Passengers should position themselves safely and within easy reach of the safety equipment.

Docking

12.02.2010 Revision: - 30/114


Nowadays it is often necessary to manoeuvre the yacht in comparatively narrow docking space. Have the fenders in place on both sides
of the boat in time and have the boat hook and mooring lines at hand.

If you are not familiar with the locality, drive into the harbour first, take a good look at your moorage, go back to sea and prepare the
fenders and lines.

To turn within a narrow space utilise the twin engines. Set the steering in the centre. To turn starboard, put the starboard engines into
reverse and the port engine into forward (vice versa if you wish to turn to port). In this way the boat will turn on its axis. However, this
operation requires some practice.

For the comfort of the passengers it is best to manoeuvre in neutral, especially with electronic controls. A sudden jerk of the lever can
result in the passengers being flung violently aboard. A loss of balance on deck may well result in a man overboard or injury. Harbour
manoeuvring in a strong wind may demand more vigorous manoeuvring and passengers and crew should be alerted in advance.

The key to successful docking is patience and calm. Docking the yacht slowly but perfectly is by far better then attempting to dock quickly
and thereby making mistakes. Plan your manoeuvres carefully. Prepare all lines on deck (bow, stern and spring lines) and position the
fenders according to the docking space.

Trim Tabs

12.02.2010 Revision: - 31/114


Trim tabs are used to bring the yacht in the perfect running angle (depending on wind, weather and load)

When in the harbour and in reverse drive, the trim tabs should always be in the 0 position.

Positions of Fenders and Lines

12.02.2010 Revision: - 32/114


12.02.2010 Revision: - 33/114


Mooring Tips
12.02.2010 Revision: - 34/114


Inform your crew of your mooring plans in advance.

Attach mooring warps to the cleats and coil them up for use.

Have the boat hook in easy reach.

The fenders must be positioned in the same height as the mooring wall, landing stage and/or other vessel.

Your crew should wear suitable life jackets while on deck.

Manoeuvre the yacht slowly at idle speed with full regard for your crew on deck.

Stay calm – there is always a next time.

Never allow the crew to jump ashore. Practice your mooring so that they can step ashore.

Relax!

12.02.2010 Revision: - 35/114


2. Safety

The yacht should be equipped with the safety equipment listed below both for short or long voyages. The equipment can of course be
supplemented according to your preferences. Regularly ensure that the safety equipment on board is in proper working order and that all
maintenance and service terms are adhered to.

Life-raft Large enough for all on board

Life-jackets For all persons on the voyage

Fire extinguishers These must be approved and certified. Ensure that all crew and passengers are familiar with the operation
and know the designated locations.

Distress rockets Daytime smoke and night rockets (Observe expiration date)

First Aid Kit Ensure that crew and passenger know its location.

Tools These should be suitable for the engines installed

Anchor and chain Familiarise yourself with the securing of the anchor and check the functioning of the windlass

Radio e.g. for weather report – observe VHF certification

Compass Ensure that it is calibrated and keep it away from magnetic, metallic objects

Fog horn DIN certification

Charts Up-to-date for the area you are cruising

It is very important that at least one crew member or passenger is familiar with the operation of the yacht. If you were injured at sea, then
somebody else can operate the yacht.

12.02.2010 Revision: - 36/114


Etiquette

Never throw rubbish or refuse overboard.

Always proceed in a manner to avoid wake and wash when passing a ship, in crowded waters or where divers may be working.

Do not use the horn, search light or VHF unnecessarily. Never pass too close to swimmers.

Know the main distress signals and never pass a ship in distress.

Always keep a look out. Serious injuries or damages to the yacht can be caused through negligence.

Always cruise at a safe speed and respect other boaters. Watch your wake!

12.02.2010 Revision: - 37/114


3. Useful Information

Yacht speed and engine efficiency

The speed of the yacht is dependent on many variables and therefore no specified speed can be guaranteed. Some of the most important
factors affecting the speed are listed below.

With normal care and maintenance the engines will maintain their top performance. If they are neglected, however, their performance will
drop off and expensive repairs may become necessary.

Atmospheric conditions

Engines will develop more power when the ambient air and water temperatures are cool. Due to the temperature the performance can
vary up to ten per cent and for this reason higher speeds are usually reached in spring and fall rather than in summer.

Personal equipment and accessories

All personal equipment, accessories and additional passengers decrease the speed. Often this effect of the additional weight is not
considered when evaluating the performance of the yacht.

Marine growth

In order to achieve maximum speed the bottom of the yacht must be kept free of marine growth. Any growth will increase the resistance of
the yacht as she moves through the water, thus decreasing the speed. The use of a good anti-fouling paint is advised.

Damaged underwater equipment

Damaged propellers, shafts or struts can cause a loss of speed and extreme vibrations. If this occurs it should be investigated
immediately.

12.02.2010 Revision: - 38/114


Propellers

The propellers are designed for speeds up to 30/32 knots with both engines at full power.

If one or both propellers are damaged, the performance of the yacht can drop drastically. This may even lead to vibrations of the shafting
on the hull. To check if the propeller/yacht match is correct, the engines should reach maximum RPM with a normal load. See engine
specification for your particular engine. If you are uncertain, contact your dealer.

12.02.2010 Revision: - 39/114


IV. Electrical System

1. Batteries and Battery Switches

Warning!
Do not temper with any electrical connections or attempt to install electrical equipment unless you are thoroughly familiar with the systems
and experienced in making such connections.

There are separate battery main switches for the domestic system, the main engines starboard and port and the generator circuit.
This main battery switchboard (see picture) is located on the aft deck in the flybridge stairs.

12.02.2010 Revision: - 40/114


All batteries on board the MAZARIN yachts are not maintenance free and require the electrolyte level to be checked regularly and if
necessary must be topped of with distilled water.

Warning!
Extreme caution must be taken when topping up the electrolyte level. Wash hands after use und clean up any spills. No smoking and no
open flames.

The batteries are divided into banks and are configured as follows:

Port engine 2 Batteries (wired for 24V)

Starboard engine 2 Batteries (wired for 24V)

Domestic services 6 Batteries (wired for 24V)

Generator 1 Battery

These switches totally isolate the batteries from all electrical equipment, except for automatic bilge pumps, sump box pumps and radio
memory supplies.

When leaving the yacht unattended, you should switch off these main switches and secure them with the built-in key against renewed
switching on. This eliminates the chance of the batteries discharging und also acts as a deterrent against thieves as it makes it very
difficult to start the engines.

When the batteries are switched on, DC voltage is supplied to the engines, the generator and the 24V switch boards. This is confirmed by
the corresponding voltmeter and control lights. The chargers for the battery system work from AC only, but independently from the status
of the battery main switches.

Caution!
Never turn the batteries off when the engines are running; otherwise the control of the alternator can be damaged.

12.02.2010 Revision: - 41/114


These battery switches only switch the positive side of the corresponding circuit. The negative side of the battery systems is connected to
various buses onboard. These are termination points for the battery cables where other items of DC equipment are connected. The
positive cables of the starting circuits also have circuit breakers.

Caution!
Do not connect other electrical equipment without an appropriate circuit breaker. Circuit protection is essential.

12.02.2010 Revision: - 42/114


1. DC System

The DC system on board the MAZARIN is divided into three areas: Domestic, engines and generator.

Domestic

The domestic system relies on DC 24V, supplied from the domestic battery bank.

DC 12V equipment is powered by a traducer.

The DC 24V main switchboard is divided into 3 circuit breaker rows.

Once the battery switches have been switched on, the domestic system is controlled from the main switchboard in the hallway in the lower
deck. All items of electrical equipment on board the MAZARIN are protected by corresponding circuit breakers.

When a circuit breaker is switched on, power is supplied to the corresponding item of equipment. Equipment should be turned ON and
OFF by its own power switch. Equipment such as the water pump does not have a separate power switch, but the circuit breakers would
normally be left in the ON position. The water pump is switched on and off by its own pressure.

The power supply of the bilge pumps, sump box pumps and the radio memory supplies is not switched off by the main switchboard.

Should an individual piece of equipment develop a fault, the circuit breaker will ‚trip’ to the off position. This will lock in this position until
the fault has been rectified.

Warning!
If a circuit breaker keeps ‚tripping’ it is important to investigate the cause. Do not attempt to bypass any circuit protection of the equipment
or the electrical system.

12.02.2010 Revision: - 43/114


Engines

The engine system relies on DC 24V, supplied form the engine battery banks. The respective battery bank is responsible for starting and
supply of the engine control electronics. The power supply for the starter and control electronics is protected by corresponding circuit
breakers.

Generator

The generator relies on one 12V/110 amp/h battery.

Switchboard cabinets

There are two DC 24V switchboard cabinets in the engine room with circuit breakers for the main consumers.

12.02.2010 Revision: - 44/114


2. AC System

There are three possible sources for the AC System:

• Shorepower (2 times 63 amp)
• Generator
• Inverter

Shore power

For the shore power to operate you must connect the yacht to suitable AC mains marina supply via the power leads supplied with the
yacht. On the MAZARIN 72 this is done via two power leads.

It is important always to first connect to the input socket on the yacht. This is located midships in the aft of the yacht.

The monitoring of the earth wire and a control of the polarity is located next to the input socket.

The circuit breakers for the 220V consumers are located in the AC main switchboard. Each consumer is protected by a corresponding
circuit breaker.

In order to choose between shore power voltage, generator voltage and inverter voltage, the switches in the shore power switchboard
located in the aft saloon are used. Systems that must not be simultaneously used (shore power and generator circuit, shore power and
inverter circuit and generator and inverter circuit) are mutually interlocked.

12.02.2010 Revision: - 45/114


Caution!
Prior to connecting to shore power all AC 230 V consumers are to be switched off, as a powerless state is required for the contact with the
shore power socket (avoiding electric arc).

Caution!
If the red polarity light illuminates, disconnect the shore power immediately and consult a qualified electrician.

Caution!
The shore power cable must always first be connected to the input socket on the yacht.

12.02.2010 Revision: - 46/114


Generator

The generator is located in the engine room. There are two control panels for starting and stopping. One is mounted on the generator
itself and the other on the remote panel located on the shore power panel in the hallway.

The main cooling of the generator is done by seawater. The generator seacock is located in the forward compartment of the engine room.
This seacock must remain ON when using the generator and the strainer regularly checked and cleaned, especially when the yacht is
being used when moored up, as debris floating in the mooring area can clog up the filter.

In addition there is an electric water valve located in the sea water supply line between the seacock and water pump. Is the generator
started this valve opens electrically, is it stopped, the valve closes electrically. This prevents that water is pushed into the generator when
the yacht is under way without generator operation.

Caution!
Failure to open the seacock when running the generator may cause the engine to overheat and cause internal damage. Ensure the
seacock is opened and remains open when running the generator.

To start the generator

Caution!
Before starting or stopping the generator make sure any loads on the system are OFF.

1. Ensure the generator seacock is open.
2. Ensure the generator battery switch is ON.
3. Check voltage at the AC Monitoring Panel.
4. Check the generator seawater strainer for water flow (glass lid).

To stop the generator

1. Turn off all AC electrical equipment.
2. Push the STOP button and let go.

On the monitoring panel in the shore power panel all engine monitoring and voltage parameters are indicated.

12.02.2010 Revision: - 47/114


Warning!
The generator and shore power supply high voltages of electricity. All work on the system to be done by qualified personnel only.

Warning!
If a circuit breaker keeps tripping, it is important to investigate the cause. Do not attempt to bypass any circuit protection of the equipment
of the electrical system.

Inverter

The inverter is located in the front bulkhead of the engine room.

It is supplied by the domestic battery system und operates the entertainment system, the 230 V refrigeration equipment and the socket
system.

When in operation the power take off must not exceed 2500 watt. When the inverter is overloaded, it automatically turns itself off and only
then again on when the load is reduced below 2500 watt.

AC System Loading

The generator and shorepower supplies can only supply a limited amount of AC current. Some marinas will only supply 10 – 15 amps of
power in an AC 240 V shoreline, when the yacht requires perhaps 32 amps, so it is possible to overload the circuit by running too many
appliances at the same time. When purchasing electrical items, care should be taken to select units with relatively low power
consumption. If the system becomes overloaded, it will cause the circuit breakers to ‘trip’. This may happen at the marina supply or the
generator load breaker. The AC equipment should be turned off or at least some of the load reduced before the load breakers are reset.

12.02.2010 Revision: - 48/114


Battery Charging

There are two methods of charging the batteries on board the yacht. One is via the battery chargers in the engine room and the other is
via the alternators on the engines and generator.

Battery Chargers

An automatic charging system is fitted to the MAZARIN 72 to enable all the batteries to be charged when the engines are not running.
This can be monitored on the domestic panel. The charger automatically reduces the charge to a nominal 1 amp when the batteries are
fully charged. This allows a continuous operation of the chargers when the yacht is left unattended.

There are two chargers on board, 100 amp ea., for the domestic system, one charger, 25 amp, for both main engine systems and one
charger, 12.5 amp, for the starter batteries for the generator. All chargers are to be turned on and off via one circuit breaker at the main
switchboard.

The state of charge of the individual battery systems can be monitored via a switchable voltmeter on the main switch board.

Whenever you arrive at a marina, plug in your shorepower and make sure the battery charger is ‚ON’. This will ensure that the batteries
are always well charged, prolonging their life and ensuring trouble-free power.

Alternator Charging

Each engine is fitted with a high output alternator, designed to charge the batteries when the engines are being used. Whenever the
engines are running, these alternators will supply a charging current to the batteries.

Each engine will charge its own set of batteries, i.e. the port engine will charge the port bank of batteries. It is a split charge system. The
corresponding diode distributor distributes the charging current of the corresponding alternator to the battery bank of the corresponding
engine and the domestic battery bank.

A corresponding LED on the diode distributor monitors their function (engine room midships aft).

12.02.2010 Revision: - 49/114


When at anchor the generator should be running so that the battery chargers can be operated to keep the batteries well charged. Without
any form of charging, running the refrigerator or the saloon lights e.g. will cause a heavy voltage loss, even after three to four hours. If you
do not wish to run the generator, all DC equipment should be turned off, especially if you plan to leave the yacht for a few hours.

When you run the yacht for extended periods of time, the battery chargers should be turned OFF as long as the engines are running. The
charging of the domestic batteries is maintained by the alternators on the engines through the split charge system and the generator
batteries are charged by the alternator on the generator.

The yacht is also fitted with a galvanic isolator. This is a device which isolates stray currents from the shore, but maintains an earth path
for the protection of the electrical system on board.

Battery Crossover

The MAZARIN 72 is equipped with a battery crossover system. This allows the separate battery circuits to be momentarily linked together
to enable the engines to be started when the batteries are low on charge.

The control for this is located on the helm station monitor. First start one engine with the fully charged batteries (check voltmeters). With
the engine running hold the crossover switch on and start the other engine. Release the switch when the engine has started.

The generator also has an emergency start crossover. The crossover switch is located next to the generator on the front engine room
bulkhead. When pushing this switch and the start switch of the generator the generator will start with the use of a domestic battery.
Release the switches once the generator has started.

12.02.2010 Revision: - 50/114


V. Fuel System

The standard fuel system on a MAZARIN 72 includes the following components:

1. 1 Aluminium fuel tank ( l capacity)
2. Fuel fillers located on deck
3. Fuel breather system
4. Manual engine and generator fuel shut off valves
5. Engine fuel conditioner
6. Generator fuel conditioner
7. Engine primary fuel filters
8. Generator primary fuel filter
9. Fuel gauge on helm stand monitors

Location of these components can be found on the Fuel System Diagram.

1. Aluminium Tank

The aluminium tank is located in a separate room in front of the engine room.
The tank is produced according to the requirements of the CE certification.

2. Fuel fillers

There are two fuel fillers on deck, one starboard, one port.
Overflowing of the tank is avoided by means of an LED and an acoustic alarm.

3. Manual Engine and Generator Shut Off Valves

The engine and generator shut off valves are located on top of the starboard side of the tank. Access to the shut off valve is under
the hatch in the pantry floor. Only the fuel feed lines have gate valves. Turning the handle at 90 degrees to the valve is the ‘OFF’
position. Turning the handle in line with the valve is the ‘ON’ position.

12.02.2010 Revision: - 51/114


4. Engine and Generator Fuel Conditioners

These conditioners are located immediately between tank and primary filter to prevent microbic contamination.

5. Engine and Generator Primary Fuel Filters

The primary fuel filters for the engines are mounted at the front of the engine room. The generator primary fuel filter is located on
the starboard side aft in the engine room. These primary fuel filters are pre-filters for the engine fuel filters mounted on the
engines. These primary fuel filters need to be changed at regular intervals depending upon yacht usage and the quality of the fuel
used. The engine primary fuel filters are monitored for water contamination by a sensor on the monitor.

6. Fuel Gauge on the Monitor of the Helm Stations

This gauge on the helm stations on the Flybridge and Main Deck shows the exact amount of fuel in the tank.

12.02.2010 Revision: - 52/114


Refuelling

Danger!

• Fuel and fuel vapours can explode
• Do not smoke while refuelling
• Switch off engines and remove key from ignition
• Do not store fuel in unventilated areas
• Before refuelling, close all portholes, windows and doors
• Do not operate engines, electrical equipment or bilge extractor while refuelling
• Use fuel only as recommended by the engine manufacturer

When purchasing fuel care is to be taken that it is clean and water free. For this reason purchase only from a reliable dealer.

Caution!
When refuelling, never leave the filler unattended. Make sure the flow rate is controlled, especially with a high-pressure fuel filler. Failure
to do this may result in a ‘blow back’ of fuel from the filler neck.

If the yacht is left unattended for a long period of time the tank should be kept as full as possible in order to minimise condensation and
accumulation of moisture in the fuel system.

When refuelling it is advisable to spray the deck with water. If there is any spillage of diesel fuel it will float on the water and is easier to
clean.

12.02.2010 Revision: - 53/114


VI. Central Hydraulic System

Control for bow and stern thrusters, bathing platform, gangway and rear hatch.

The central hydraulic system is located starboard in the aft engine room.

The system comprises the following components:

1. A hydraulic oil reservoir with 2 electrically driven hydraulic pumps.
2. Two hydraulic pumps (PTO pumps) flanged to the main engine.
3. Electro-magnetic driven hydraulic valve block for the operation of all hydraulic components, located on top of the oil reservoir
12.02.2010 Revision: - 54/114


Oil level

1. Prior to starting the engines, check the oil level through the oil level gauge glass on the oil reservoir
2. Check the filter on the oil reservoir. If the red pin is up have the filter changed by qualified personnel.

Caution!
Hydraulic pressure can reach as much as 180 bar. Do not interfere with any pressure settings and do not obstruct the safe travel of any
hydraulic equipment.

Operation of the bathing platform and the garage rear hatch.

1. The control panel is on the main deck aft starboard in the side bulwark.

12.02.2010 Revision: - 55/114


2. To operate the bathing platform the trim tabs must be lowered by pushing the left switch in the control panel until the green light above
the switch „Badeplattform“ lights up.

3. The rear garage hatch can be operated only if the bathing platform is sufficiently lowered and the green light above the switch “Hatch”
lights up.

Warning!

• Prior to lowering the bathing platform, the bathing platform must be raised for 2-3 seconds in order to relieve the grabs
• Do not exceed the maximum load capacity (450 kg)
• Distribute the weight evenly when lifting the bathing platform
• For safety reasons it is not possible to start the main engines when the bathing platform is in the lowered position
• Manual emergency operation of the bathing platform, rear garage hatch and gangway

A manual pump for emergency operation is aft under the stairs in the crew cabin.
Manual operation of the corresponding magnetic valves on the hydraulic valve blocks is necessary.

12.02.2010 Revision: - 56/114


Hydraulic Steering

The steering system consists of the following items:

a. 2 Rudder blades with tiller shafts and a connection rod
b. Autopilot with solenoid valve
c. Rudder cylinder (power assisted) – located aft under the garage
d. Helm pumps on upper and lower helm station with steering wheels

The direction of the steering is controlled by the helm pump mounted directly onto the steering wheel. This pump has 3 oil lines.

The rudder system is power assisted by the PTP pumps.

In case of failure of the PTP pumps the rudder system can be emergency operated via direct steering with the helm pumps.

Fluid level

The fluid level in the steering reservoir in the upper helm station is to be checked regularly. During normal operation with the engines
running the oil is constantly refilled.

12.02.2010 Revision: - 57/114


Bleeding

If air should enter the rudder hydraulic system and operation becomes impossible, the following steps are to be taken:

Turn the autopilot solenoid valve in one direction and steer in the opposite direction with the helm pump on the upper helm station. When
the rudder is in the end position, turn off the autopilot solenoid valve and steer with the helm pump into the other end position. Repeat until
normal operation is restored.
If necessary, repeat the same on the lower helm station.

12.02.2010 Revision: - 58/114


VII. Toilet System

The waste system on the MAZARIN 72 consists of the following items:

a. Black water holding tank
b. One electric discharge pump
c. Four electric toilet pumps
d. Two diverter valves
e. One monitoring and operating panel

Caution!
The toilet system uses fresh water from the water tank, so ensure that there is water in the tank before using the toilet system.

Diverter Valve

The toilets are equipped with electrical pumps to dispose of the waste.

The waste from the toilet can be pumped straight to sea or into the black water holding tank. This is done by means of the diverter valve
located in the mid bilge compartment area by using the diverter valve handle and selecting either “To Sea” or “To Tank”. The longer end of
the lever should be pointed towards the required flow direction.

Caution!
If the toilet waste is being pumped out to sea, ensure that the toilet outlet valves are open. Otherwise damage to the pump valves may
result.

12.02.2010 Revision: - 59/114


Toilet Operation

1. Ensure seacocks are open before use.
2. Ensure the appropriate circuit breakers are on.
3. The toilet is ready for use when the green LED light lights up
4. Before use push the button „before use“
5. After use push the button „after use“
6. The small amount of water left is automatically siphoned off.

Holding Tank Operation

Please check local regulations regarding holding tank usage before discharging waste into the sea or river.

The holding tank is of limited capacity and is for short term use only. It must be flushed out every 2 or 3 days. Otherwise unpleasant
odours may build up und will be very difficult to remove from the yacht.

When the holding tank becomes full, the „Holding Tank Full“ light will flash on the switch panel, an acoustic signal is given and the red
LED on the toilet lights up.

If the „Full“ light flashes and the red LED on the toilet is lit up, do not use the toilets until the holding tank has been pumped out.

Opening and Closing of the Holding Tank Seacock
The switch for this valve is located on the main battery switchboard. If the switch is in the position OPEN the draining pump will
automatically start to operate when the filling level alarm is triggered. After the pumping out, the pump automatically shuts down and the
switch must be put in the position CLOSED.
If the tank is to be pumped out and the filling level alarm has not yet been triggered, the switch must be put in the position OPEN and the
draining pump must be turned on and off with the switch located on the port side of the front Jet Ski garage bulkhead. After having
switched off the pump, the seacock must be closed again by putting the switch on the main battery switchboard in the position CLOSED.

Deodorant can be added via the Deck Waste Pump Out. If the holding tank is not to be used for some time, it is good practise to turn the
seacock off.

12.02.2010 Revision: - 60/114


The holding tank pump stops only then when the tank is empty. Should it become necessary to stop the pump before the tank is empty,
the corresponding circuit breaker must be switched off. The holding tank system is also equipped with an outlet on the upper deck for
pumping the waste out at an appropriate station. Depending on the area and local regulations, pumping the waste out to sea may be
against the law, incurring large penalties, so the waste must be pumped out at an appropriate station. The pump out stations are normally
equipped with suitable adapters to fit the deck outlets and pumping is done from the shore.

For the holding tank pumps to operate and the „Holding Tank Full“ lights to work, the holding tank circuit breakers must be ON.

12.02.2010 Revision: - 61/114


VIII. Bilge Pump System

The bilge pump system of the MAZARIN 72 consists of the following items:

• 7 electric bilge pumps
• 2 electric flood pumps
• 3 manual bilge pumps
• 2 flood pump float switches
• 6 bilge pump float switches

Location of these items can be found on the Bilge Pump Location diagram.

The pumps fitted to the MAZARIN 72 are extremely reliable and have the ability to run dry without damaging any of the seals within the
pump. All the pumps are operated by float switches, which are activated should the water level rise in the bilge.

In addition there are manual switches on the helm station, which are used to override the float switches located on the internal AC circuit
breaker panel.

On the monitor is a warning light connected to an alarm which is activated if the flood pumps operate. The alarm and the light will also
work when you turn this pump on by using the manual switch.

It is important to note that the automatic bilge system is permanently connected to the batteries. Even if the battery switches and circuit
breakers are turned off, the automatic bilge pump system will still work.

It is very good practice to keep the bilges dry; first to keep the excess weight down and also to note any leaks appearing, particularly in
the engine room.

12.02.2010 Revision: - 62/114


In addition to the electric bilge pumps, there are 3 manual bilge pumps: 1 in the engine room, 1 in the front bilge and one in the service
shaft. Operation is simple: insert the handle in the pump socket and use long hard strokes. The water will be pumped overboard.

Caution!
Take care to ensure that no debris such as rags or cloth is left in the bilge as this could prevent the unit from pumping the water.

12.02.2010 Revision: - 63/114


X. Air Conditioning

The air conditioning system fitted has full environment control. It will either cool or heat the cabins to a constant temperature and is
operated from the AC 220/240V mains supply. They will only operate when the shorepower is connected or the a generator is in
operation.

The air conditioning system of the MAZARIN 72 consists of the following items:

• 9 Air handlers
• Chiller System
• 1 sea water outlet

Location of these items can be found on the Air Conditioning diagram.

Each unit has its own individual switch located on the control panel in
the lower staircase.

12.02.2010 Revision: - 64/114


Caution!
When the unit is running, it is very important to verify that there is water flowing through the system. Check the outlet for a continuous flow
of water. Severe damage may occur if the system is run dry.

12.02.2010 Revision: - 65/114


Each unit has its own electronic control pad, designed so that the temperature in each cabin can be controlled independently.

I/O
In normal operation this will switch the unit between the Standby and On condition. When the unit is switched off it will remember the last
set point temperature, fan speed and operation in non-volatile memory.


This button selects the fan operation. Pressing it for a moment will show the current fan setting. This can be 1,2,3,4,5,6, or A. Fan setting
1 is the slowest, and 6 is the fastest. Fan setting A will let the unit control the fan speed automatically, slowing as the temperature reaches
the set point. To change the fan setting either press and hold the button, or press it several times until the desired setting is reached.
Several seconds after the button is released, the display will revert to showing the temperature and the fan speed will gradually change to
its new setting.

12.02.2010 Revision: - 66/114



The Up button displays and increases the set point temperature. Pressing it for a moment will display the set point temperature. To
increase the set point temperature either press and hold the button, or press it several times until the desired set point temperature is
shown. Several seconds after the button is released, the display will revert to showing the temperature.


The Down button displays and decreases the set point temperature. Pressing it for a moment will display the set point temperature. To
decrease the set point temperature either press and hold the button, or press it several times until the desired set point temperature is
shown. Several seconds after the button is released, the display will revert to showing the temperature.

SELECT

The Select button allows the operating mode to be selected. The available operating modes are:

 Cooling mode. In the cooling mode the unit will cool the room to the set point if chilled water is available. The unit will not attempt
to warm the room.

 Heating mode. In the heating mode the unit will heat the room to the set point if heated water is available. The unit will not attempt
to chill the room.

AUTO

Auto mode will attempt to heat or cool the room to maintain the set point temperature. The correct water temperature must be available to
enable it to work, i.e. chilled water for chilling, hot water for heating.

 The dehumidifier is not available on water circulation systems and cannot be selected.

12.02.2010 Revision: - 67/114


Operation in HEAT Mode

1. Ensure the seacocks are open before use.
2. Check circuit breakers are ON.
3. Turn on the air handler by pressing the I/O button on the control pad. This energises the fan.
4. The display will show the current room temperature.
5. Select the desired temperature, higher or lower, using the up and down arrows.
6. The fan speed 1-6 is selected by pushing and holding the fan button. For automatic control, keep the fan button pressed until “A” is
displayed.
7. To turn off the unit, press the I/O button.

Thermostats on the HFL cooling and heating systems provide an automatic change from cooling to heating with a 1.5°C differential. If the
thermostat is left stationary after being set, the unit will cycle from cooling to heating as needed.

Each air conditioning unit, whether under the saloon seating or under a berth is fitted into an area which is insulated with soundproof
material. There is however an opening for each area, usually with a grill at floor level, this is for the return air supply for each unit, so it is
very important to ensure that these grilles or openings do not become blocked or covered. This grille must be cleaned at regular intervals
as a build up of dust particles will restrict the air flow returning to the unit.

When lifting the yacht out of the water, it is good practice to turn off the air conditioning seacock. This will stop the water draining out of
the pumps, otherwise it may be necessary to bleed the system when the yacht goes back into the water.

 For the correct operation and maintenance of the air conditioning system, please refer to the appropriate manual.

12.02.2010 Revision: - 68/114


X. Water System

1. Fresh Water System

The fresh water system on board your MAZARIN 72 consists of the following items:

• Stainless steel water tank (800 l)
• 24 V water pump and coarse filter
• 1 Deck water filler and tank breather
• 1 Water tank level gauge
• Calorifier
• 2 Diaphragm pressure tanks
• Water maker

Location of these items can be found on the Fresh Water System Location Diagram.

There is a single water tank on the MAZARIN 72 located underneath the jet ski garage. It is filled by the deck filler and vented on the port
side. The water is pumped around the system in high quality PVC pipe, through two separate circuits, hot and cold. The cold water circuit
starts from the fresh water pump and the hot circuit starts from the calorifier in the crew cabin.

The water pump is fully automatic with an in-built pressure switch, which pumps the water around the system. When the pressure in the
system drops below 2 bar, the pump will cut in and run until the pressure increases to approximately 3 bar. Next to the water pump is a
coarse filter. This must be inspected und cleaned regularly.

The fresh water pump is located in the engine room on the port side.

 For the correct operation and maintenance of the fresh water pump, please refer to the appropriate manual.

12.02.2010 Revision: - 69/114


Priming the system

1. Fill the tank with fresh water.
2. Open all taps, hot and cold.
3. Ensure that all drains are clear.
4. Switch water pump ON and allow time for water to pump around the system and fill the calorifier.
5. As the water becomes steady and free of air, close the taps. Turning off the last tap should cause the pump to shut off.

When the water tank is completely full, water will overflow through the tank vent. Therefore it is important to check the water level gauge
on the console when filling and turn off the water supply when the tank is full.

Hot Water

The fresh water is heated by one of two methods: either by running the engines or by the calorifier.

When the engines are running, the cooling water (around 75°C) from the engines flows through a heat exchanger, which heats the fresh
water in the tank.

Alternatively, providing the generator is running or the shorepower is plugged in to the yacht, the water can be heated by switching on the
electric AC220V water heater on the main AC Circuit Breaker panel. This immersion heater is thermostatically controlled and will cut out
automatically when the water temperature reaches the set point. This is unnecessary when the engines are running.

Warning!
Never operate the electric immersion heater when the water system is empty as this could result in an explosion.

Caution!
Hot water can scold. Be careful when using hot water, especially when the yacht is moving.

12.02.2010 Revision: - 70/114


Shore Water Support

Located on the stern of the yacht is a unit which provides for shore water support. This enables you to connect a hose pipe from a marina
fresh water supply directly into the fresh water system of the yacht. The yacht uses shore water and relies on the water pressure form the
shore to pressurise the system.

It is very important to remember when using the shore water support to turn the water pumps ‘OFF’, otherwise the pump will still operate
and use the fresh water from the water tank on board.

Please note!
If the shore water connection is made, it will NOT fill the fresh water tank whether the water pumps are ‘ON’ or ‘OFF’.

If the pressure of the water from the shore is extremely high, the unit will automatically reduce this pressure to 2 bar. This will avoid the
risk of damaging any water fed equipment on board the yacht.
Don’t forget to disconnect the shore water support and to turn the water pumps ‘ON’ when you leave the marina.
.

Caution!
Be sure to check the quality of the marina fresh water supply, especially if planning to drink it or use it for cooking. Don’t forget the ice
maker will use this water as well.
