BEFORE YOU SET OFF
Familiarise yourself with this owner’s manual.
Always check at least the following items before leaving:
−
−−
− Weather conditions and forecast
Take the wind, waves and visibility into account. Are the design category, size and
equipment of your boat, as well as the skills of the skipper and crew, adequate for the
waters you are headed for? Hull windows and hatches must be battened down during
high wind and rough seas to prevent water incursion.
−
−−
− Loading and stability
Do not overload the craft, and distribute loads appropriately. Heavy items are to be
placed in the storage compartments under the aft bench. Also note that the boat is less
stable if people stand up when on board.
−
−−
− Passengers
Ensure that there are personal flotation devices or lifejackets for all people on board.
Agree on crew tasks before setting off.
−
−−
− Fuel and fuel system
ake sure that the boat has enough fuel, including a 20% reserve for heavy weather or
other unforeseen eventualities.
−
−−
− Engine and manoeuvring equipment
Check the function and condition of steering and remote control, and carry out routine
checks according to the engine manual.
−
−−
− Seaworthiness
Check the boat’s seaworthiness: no fuel or water leaks, safety equipment available on
board, etc. Check that there is no water in the bilge.
−
−−
− Fastening of equipment
Check that all onboard items are positioned so that they will stay in place even in rough
seas and high winds. Please note that the seat cushions may fly overboard if they are not
fixed properly with press studs.
−
−−
− Nautical charts
Unless you are navigating in completely familiar waters, ensure you have nautical charts
on board that cover a large enough area! If your boat is equipped with a chart plotter,
learn to use it before setting off. Ensure that the plotter charts are of the latest edition.
−
−−
− Leaving the berth
Agree with the crew who will release each mooring line, etc. Be careful not to let
mooring lines or the anchoring line become fouled in the propeller during manoeuvring.

1 General
The owner’s manual will help you familiarise yourself with the properties and features of
your new boat and with its care and maintenance. Separate manuals for installed equipment
are attached and are referred to in many sections of the owner’s manual. You can
supplement this user manual by adding the manuals of devices which are installed
afterwards. Space has been left for your own notes at the end of the manual.
The craft has a running serial number, a CIN-code (Craft Identification Number). The CIN-
code can be found on the starboard side of the transom just below the bathing platform. We
recommend that you write down the CIN-code in the declaration of conformity on the
following page. When contacting the dealer, please provide the CIN code and the type of
craft. This helps in delivering the correct spare parts.

2 Definitions
The warnings and cautions in this manual are defined as follows:
DANGER Denotes an extreme intrinsic hazard that will result in a high probability
of death or permanent injury if proper precautions are not taken.
WARNING Denotes a hazard which can result in injury or death if proper
precautions are not taken.
NOTE Denotes a reminder of safe practices or directs attention to unsafe
practices which could result in personal injury or damage to the craft or
components or the environment.
SI system units are used in this manual. In some cases, other units have been added in
brackets. An exception is wind speed, for which the Beaufort scale is used in the
Recreational Craft Directive.
3 Warranty
The boat and its factory-installed equipment have a two-year warranty, starting on the first
day of use. Please contact your dealer regarding any potential warranty issues. Please
remember to provide the CIN code. If possible, please provide a digital photograph of the
subject of your claim. This usually speeds up the claims process.
4 Before use
4.1 Registration
Registration regulations vary between different countries. Find out what is required in
relation to your own boat.
4.2 Insurance
Boat insurance can compensate damage occurring on water or during transport and lifting.
Check who has insurance liability each time when having the boat lifted. Insurance also has
an indirect effect on safety at sea: In the event of a serious accident or damage, you must,
above all, concentrate on saving people. Insurance companies will be able to give more
information about different insurance alternatives. Check who has insurance liability each
time when having the boat lifted or transported!

Yamarin 79 Day Cruiser 11 (53)
4.3 Training
No one is a born sailor. There is plenty of boating literature available. Navigation courses are
arranged by local yacht clubs or national boating associations where you can gain basic skills.
However, please remember that you only become confident in boat handling, navigation,
docking and anchoring after long practical experience.

5 Characteristics and use of your boat
5.1 General
The user manual is not meant to be a complete service or repair manual; it simply guides the
user to use his/her boat in a proper way.
5.2 Basic data
Recreational crafts can be constructed according to 4 categories (A, B, C and D)
under the Recreational Craft Directive 94/25/EC. This boat has been
constructed according to design category C. The meanings of the various
design categories are explained below.
Category A: The boat is built for conditions where wind speed can exceed 8
Beaufort (approx. 21 m/s), and where the significant height of the waves
(please refer to note below) can exceed 4 metres. In such circumstances the
boats are largely self-sufficient. Category A does not include abnormal
conditions such as hurricanes. Such conditions may be encountered on
extended voyages, for example when crossing oceans, or in coastal areas
where there is an open expanse of sea for several hundred nautical miles off
the coast.
Category B: The boat is built for conditions where wind speeds can reach a
maximum of 8 Beaufort (approx. 21 m/s), and where the corresponding
significant height of the waves (please refer to note below) is 4 metres at most.
Such conditions may be encountered on offshore voyages of sufficient length,
or on coastal waters when unsheltered from the wind and waves for several
dozens of nautical miles. These conditions may also be experienced on inland
seas of sufficient size for the wave height to be generated.
Category C: The boat is built for conditions where wind speeds can reach a
maximum of 6 Beaufort (approx. 14 m/s), and where the corresponding
significant height of the waves (please refer to note below) is 2 metres at most.
Such conditions may be encountered on exposed inland waters, in estuaries,
and in coastal waters in moderate weather conditions.
Category D: The boat is built for conditions where wind speeds can reach a
maximum of 4 Beaufort (approx. 8 m/s), and for corresponding seas (significant
wave height does not exceed 0.3 metres, and the height of the greatest waves
does not exceed 0.5 metres). Such conditions may be encountered on
protected inland waters, and in coastal areas during fine weather conditions.
Note: Significant wave height is a term used in boat design. In practice, significant
wave height means the average height of the highest third of all wave heights
measured in the waters. If the significant wave height is 2.0 m, the mean height
of all waves is roughly 1.2 m.

5.3 aximum recommended number of passengers:
The boat's maximum recommended number of passengers is eight persons.
WARNING Do not exceed the maximum recommended number of
passengers. Regardless of the number of passengers, the total
weight of people and equipment must never exceed the
maximum recommended load (please refer to Section 5.4,
“Loading”). Always remain seated on the boat. All persons on
board must remain seated while the boat is moving.

Yamarin 79 Day Cruiser 16 (53)
Image: Seats on the boat
5.4 Loading
The boat's maximum permitted load is 1,035 kg. This load includes the following weights:
a) The total weight of passengers 600 kg (the default weight of an adult is assumed to
be 75 kg and that of a child 37.5 kg)
b) Basic equipment 30 kg
c) Liquids (fresh water, fuel, etc.) in fixed tanks 265 kg
d) Personal equipment (e.g. recreational and camping equipment) 80 kg
e) Other load (full septic tank) 30 kg
f) Possible life raft 30 kg
NOTE The maximum permitted load only includes the weights
mentioned above.
WARNING Never exceed the maximum recommended load when loading
the craft. Always load the craft carefully and distribute loads
appropriately so that the boat is on an even keel. Heavy
equipment should usually be placed in the storage compartment
under the aft seat. If the boat is carrying the maximum number of
passengers, heavy items should be placed in the bow so that the
boat will not be tail-heavy. Always avoid placing heavy items high
up.
5.5 Engine and propeller
The maximum recommended engine power for the boat is 300 hp (220 kW). Do not use the
boat with an engine that has an output higher than the kW limit given on the CE plate. Using
a more powerful engine than specified on the CE plate will void the boat’s warranty. Follow
the dealer’s instructions when choosing the propeller for your craft.
NOTE Do not turn the engine when the engine well's hatch is resting on
the hood. The warranty does not cover damage caused by the
hatch to the hood.
5.6 Prevention of water incursion and stability
5.6.1 Hull and deck through fittings and closing valves
The boat has a rainwater draining system, which means that rainwater is drained from the
undecked part of the boat when the boat is on the water. The system also functions when
the boat is out of water, provided that the bow is higher than the stern and closing valve is

Yamarin 79 Day Cruiser 17 (53)
open. The rainwater drainage closing valve is located under the middle hatch of the aft seat.
This drain valve is meant to be shut only when at maximum load to prevent potential water
incursion. In other loading conditions the drain valve should remain open to let rainwater
drain from the boat.
The boat is equipped with two bilge pumps, at the locations indicated in the figure below.
The electric bilge pump has a capacity of c. 65 l/min and the manual pump's capacity is c. 0.5
l/pull.

3. anual bilge pump's drainage through fitting 8. Shut-off flap
4. Open deck space drainage pipe 9. Electric bilge pump
5. Rainwater drainage valve
The owner of the boat is responsible for ensuring that there is at least one baler or bucket
on the boat and that it has been secured.
WARNING The bilge pump system is not intended to cope with a leak caused
by running aground or other equivalent damage (hull damage).
SAFETY MEASURE Regularly check to ensure that there is no debris at the end of the
suction hoses of the bilge pumps. You can check the electric bilge
pump by detaching the large plywood panel (= tank space hatch)
under the aft bench. The pump is not secured into its casing, so

Yamarin 79 Day Cruiser 18 (53)
you can lift it out by the hose. The end of the manual pump's hose
is located between the fuel tank and transom, so it can also be
inspected once you have detached the large plywood panel under
the aft bench.
WARNING Always keep the drainpipe shut when its inboard end is constantly
below the waterline due to loading. The shut-off flap on the
transom only prevents water from entering the boat when
reversing!
NOTE ake sure that water can flow unobstructed through the
drainpipe. Debris such as autumn leaves may obstruct the water
flow, which can cause the boat to fill with water and sink. The
bilge pump system does not work in conditions below 0°C.
NOTE There is always some condensed water in the bilge. A small
amount of water may also come through the hull through fittings,
especially as the boat ages. Always remember to check the bilge
before you leave the boat at quay or buoy, and always before
setting off. Have any leaks repaired at an authorised repair shop.
WARNING The boat’s handling properties may become extremely dangerous
if there is water in the bilge.
WARNING The boat's hull windows must be kept closed when the boat is
moving. Also close the windows when you leave the boat at pier
or buoy. In rough weather, hatches, drawers and doors should be
kept shut to minimise the risk of them filling with water.
5.6.2 Stability and buoyancy
Please note that stability will be reduced by any weight added high up on the boat. Any
change in the distribution of weight on board may significantly affect the stability, trim and
performance of your craft. Please remember that large breaking waves always present a
serious danger to stability.

Yamarin 79 Day Cruiser 19 (53)
5.7 Preventing fires and explosion hazards
5.7.1 Refuelling
Shut off the engine and extinguish any cigarettes before starting to refuel. During refuelling,
do not use switches or appliances that can cause a spark.
If the nozzle shuts off in the middle of refuelling, turn it roughly 90 degrees to prevent the
fuel jet from hitting the chain's mounting screw.
When refuelling at a service station, do not use a plastic funnel, since it will prevent the
tension between the refuelling nozzle and filling vent from being discharged.
Hint: If you are afraid of getting fuel on the teak deck during refuelling, wet the deck with
water. You can also hold a rag in front of the fuel filler to prevent fuel from splashing on the
deck.
Always keep a spare can of fuel on board. The anchor boxes at the stern are especially
suitable for storing the spare canister. There is no risk of vaporised fuel coming into contact
with battery compartments or the electrical system from either of these boxes.
Do not stow any loose items under the aft seat that could prevent fuel flow to the engine if
they shift. This is particularly important for items that may press against hoses or the fuel
filter. Check the fuel hoses annually for wear, especially at through fittings.
Please note that, depending on the trim of the boat or the boat's heeling angle, it might not
be possible to use the full capacity of the tanks.
WARNING Vaporised fuel is highly explosive. Observe these instructions and the utmost
caution during refuelling. The smell of fuel always means that there is
vaporised fuel on your boat.

Yamarin 79 Day Cruiser 20 (53)
5.7.2 Other fuel-operated systems (stove and heater)
The stove and paraffin heater (optional accessory) have their own user manuals and their
operation is not described in detail in this manual. The fuel tanks for the stove and heater
are located under the left aft bench. Only use good-quality paraffin as fuel. Turn off the
stove and heater when refuelling the paraffin tank. When handling paraffin, do not use
switches or appliances that can cause a spark. Always clean any spilled fuel immediately.
