Owner’s Manual

English
FOREWORD
Congratulations on choosing a Yamarin boat! We are delighted to welcome you as a Yamarin owner.
The intention of this manual is to help you to operate your craft safely, with maximum enjoyment
The manual contains details of the craft, the equipment supplied or fitted, its systems and informa-
tion on its operation, care and maintenance. Please read it carefully, and familiarise yourself with
the craft before using it.
Naturally, the owner’s manual is not a course on boating safety or seamanship. If this is your first
craft, or you are changing to a type of craft you are not familiar with, for your own comfort and safe-
ty, please ensure that you obtain handling and operating experience before “assuming command”
of the craft. Your dealer or national sailing association or yacht club will be pleased to advise you of
local boating schools, or competent instructors.
This owner’s manual is not a detailed maintenance or trouble shooting guide. In case of diculty
please contact the dealer. Always use qualified and competent people for the maintenance, repair
and modification of the boat. Modifications that may aect the safety characteristics of the craft
shall be assessed, executed and documented by competent people. The manufacturer is not re-
sponsible for modifications he has not approved.
Always keep your boat in a good condition and be aware that the boat requires maintenance and
servicing. Any craft – no matter how strong it may be, can be severely damaged if not used proper-
ly.
Always adjust the speed and direction of the craft to sea conditions.
All persons should wear a suitable buoyancy aid (Life jacket/Personal Flotation Device) when on
deck.
We wish you many enjoyable times on-board your Yamarin boat!

BEFORE YOU SET OFF
Familiarize 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 water area you are aiming
for? During use, hull windows and other hatches must be battened down to prevent water incursion
Loading and stability
Do not overload the craft and distribute loads appropriately. To avoid impairment of the craft’s sta-
bility, do not place heavy items high up. Please consider that the stability of the boat is reduced if
people stand up when on-board during use.
Passengers
Ensure that there is Personal Flotation Device or Lifejackets for all people on-board. Agree crew
tasks before setting o.
Fuel and fuel system
Make sure that the boat has enough fuel. Keep in mind that rough conditions at sea impact on fuel
consumption and that it can increase by more than 30% when compared to calm conditions. As
a rule of thumb, you should aim for there being at least 20% left in the tank when arriving at your
destination. Regularly check the fuel filter to ensure that there is no water in the moisture trap lo-
cated under the fuel filter itself. The fuel filter should be changed 1-2 times per year depending on
engine hours and quality of fuel.
Engine and maneuvering equipment
Check the function and condition of steering, batteries and remote control and carry out routine
checks according to the engine manual
Boat’s seaworthiness
Check the boat’s seaworthiness: no fuel or water leaks are permitted, safety equipment must be
available on-board etc. Check that there is no water in the bilge!
Fastening of equipment
Check that all equipment and heavy items are positioned so that they are held in place during
travel at sea and high winds. Please note that the seat cushions may fly overboard if they are not
fixed properly with press studs.
Nautical charts
If you are not navigating in familiar waters, ensure you have nautical charts on-board that cover a
large enough area. If your boat is equipped with a chart plotter, familiarize yourself with it before
setting o. 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 to tangle in the propeller during maneuvering.
Obligatory equipment
What is considered obligatory equipment varies from country to country. Find out what is required
for your boat.

English
You will find additional instructions concerning the engine in a separate manual.
1. General
The owner’s manual will help you to become familiarized with the properties and features of your
new boat, as well as 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, of course, comple-
ment this owner’s manual by adding the manuals of devices which are installed afterwards. There is
also space for your own notes at the end of this manual.
The craft has a running serial number, CIN-code (Craft Identification Number). The CIN-code can
be found on the starboard side of the transom just below the rub rail. We recommend that you
write down the CIN-code in the declaration of conformity in this book. 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 following:
DANGER!
Denotes an extreme intrinsic hazard exists which would result in high probability of death
or irreparable injury if proper precautions are not taken.
WARNING!
Denotes a hazard exists which can result in injury or death if proper precautions are not
taken.
NOTE!
Denotes a reminder of safety practices or directs attention to unsafe practices which
could result in personal injury or damage to the craft or components.
The units used in this manual are in accordance with the SI-system. In some cases, other units have
been added in brackets. An exception is the wind speed, where the Beaufort scale is used in the
recreational craft directive.
3. Warranty
The boat and the equipment installed at the boat factory are guaranteed for 2 year, starting from
the first day of use. Please contact your dealer in relation to 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 from country to country. 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
9

English
insurance liability separately when lifting the boat. Insurance also has an indirect eect on safety at
sea: In the event of a serious accident or damage, you must, above all, concentrate on saving peo-
ple. Insurance companies will be able to give more information about dierent insurance alterna-
tives. Be particularly careful to check insurance liability when you lift and transport the boat!
4.3. Training
No one is a born sailor. There is plenty of boating literature available. Navigation courses are ar-
ranged by local yacht clubs or national boating associations where you can gain basic skills. How-
ever, 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 owner’s manual is not meant to be a complete service or repair manual, but to guide the user
to know the characteristics of the boat and 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) according to the
recreational craft directive 2013/53/EU. Yamarin 50 BR is constructed according to category C. Be-
low you will find information on what each category means:
Category A: The boat is built for conditions where the wind can exceed 8 Beaufort (approx. 21 m/s)
and where the significant height of the waves (please refer to note below) can exceed 4m. In such
circumstances the boats are largely self-sucient. Category A does not include abnormal condi-
tions such as hurricanes. Such conditions may be encountered on extended voyages, for example
across oceans, or in coastal areas where there is an open expanse of sea for several hundred nauti-
cal miles o the coast.
Category B: The boat is built for conditions where the wind reaches a maximum of 8 Beaufort
(approx. 21 m/s) and where the significant height of the waves (please refer to note below) does
not exceed 4m. Such conditions may be encountered on oshore voyages of sucient 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 sucient size for the wave height to
be generated.
Category C: The boat is built for conditions where the wind reaches a maximum of 6 Beaufort
(approx. 14 m/s) and where the significant height of the waves does not exceed 2 m (please refer
to note below). 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 the wind reaches a maximum of 4 Beaufort
(approx. 8 m/s) and where the significant height of the waves (please refer to note below) does not
exceed 0.3 m and the height of the greatest waves is no more than 0.5 m. Such conditions may be
encountered on protected waters on lakes and in coastal areas during fine
weather conditions.
10

English
Note:
Significant wave height is a term used when planning to build a boat. The significant wave
height is the mean height of the highest one third of the waves, which approximately cor-
responds to the wave height estimated by an experienced observer. In the event, that the
significant wave height is 2.0 m the mean height of all waves is roughly 1.2 m.
Maximum recommended load:
See technical specifications
Please also refer to section 5.5 “Loading”.

English
NOTE!
If you load the boat from stern to bow, you will have better fuel economy.
5.5. Loading
The maximum permitted load for the Yamarin 50 BR is 905 kg. This load includes the following
weights:
the total weight of passengers 450 kg
(the default weight of an adult is assumed to be 75 kg and that of a child 37,5 kg)
consumable liquids (fuel) in fixed tanks (64 L x 0,75kg) 48 kg
Basic equipment 15kg
Stores & cargo 136kg
NOTE!
The maximum permitted load includes only weights mentioned above.
WARNING!
When loading the craft, never exceed the maximum recommended load. Always load the
craft carefully and distribute loads appropriately (roughly an even keel). Heavy equipment
should usually be placed in the storage compartment under the aft seat. Always avoid
placing heavy weights high up.
5.6. Engine and propeller
The maximum recommended engine power for the Yamarin 50 BR is 60 hp (44,8 kW). The con-
struction of the boat is not designed to bear more power than 60 hp. The maneuverability of the
boat can be very dangerous if the boat has bigger than 60 hp engine. The warranty is not valid if
boat is used with more power than 60 hp. Follow the dealer’s instructions when choosing the pro-
peller for your craft
13

English
5.7. Prevention of water incursion and stability
5.7.1. Hull and deck thru fittings and closing valves
The Yamarin 50 BR 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 open. The closing
valve (number 2 in the next picture) is located under the back seat. This drain valve is meant to be
shut at maximum load to prevent potential water incursion. In other loading conditions the drain
valve should remain open.
The boat is equipped with a manual bilge pump shown in the picture below. The hand pump has a
capacity of 0.5 l/pull.
1. Manual bilge pump
2. Rain water 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 leakage caused by running aground
or other equivalent damage.
PRECAUTION!
Regularly check to ensure that there is no debris at the end of the suction hose for hand
pump. The bilge pump suction hose is in the rear end of bilge. You have a service access
through rear compartments inspection hatch.
WARNING!
Always keep the drainpipe shut when its inboard end is constantly below the waterline
due to the load. The shut-o flap on the transom only prevents water from entering the
boat when reversing!
NOTE!
Make sure that water can flow unobstructed through the drainpipe. For instance, 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.
1
2
14

English
NOTE!
There is always some amount of condensed water in the bilge. As the boat ages, there is a
risk that a small amount of water may come through the hull bushings. Always remember
to check the bilge, via the inspection hatch under the aft seat before you leave the boat
at quay or buoy and always before setting o. Have an authorized repair shop check for
possible leaks.
WARNING!
The boat’s handling properties may become extremely dangerous if there is water in the
bilge.
WARNING!
In rough weather, the hatches and drawers should be kept shut to minimize the risk of
them filling with water.
5.7.2.Stability and buoyancy
Please note, that stability is reduced by any weight added high up. Any change in the distribution of
the weight onboard may significantly aect the stability, trim and performance of your craft. How-
ever, please remember that large breaking waves always present a danger to stability.
5.8. Avoiding the risk of fire or danger of explosion
5.8.1.Re-fueling
Shut o the engine and extinguish any cigarettes before starting to refuel. During re-fueling, do not
use switches or appliances that can cause a spark.
If the nozzle shuts o while you are re-fueling, you should rotate the nozzle by 90 degrees to pre-
vent the jet from landing directly on the chain mounting screw.
Always keep a spare can of fuel onboard. A suitable place for stowing the spare can, especially con-
sidering fire safety, is either of the anchor boxes in the stern. There is no risk of gasified fuel coming
into contact with battery compartments or the electrical system from either of these boxes.
Do not stow any loose items under aft seat that, if moved, could prevent fuel from going to the
engine. This is particularly important for items that may move against hoses running to or from the
fuel filter. Check annually that the fuel hoses are not worn at lead-ins.
Please note that, depending on the trim of the boat or the boat’s heeling angle, it might not be pos-
sible to use the full capacity of the tank.
5.8.2. Fire protection
The boat is equipped with a portable 2 kg fire extinguisher class 8A 68 B. The portable fire extin-
guisher must be serviced annually by an authorized inspector. In the event, that the fire extinguish-
er is replaced the capacity of the new one should be the equivalent of the old one.
15

English
Location of fire extinguisher in Yamarin 50 BR:
1
1. Fire extinguisher
Ensure that fire-fighting equipment is readily accessible even when the boat is loaded. Inform
members of the crew about the location and operation of fire-fighting equipment.
Remember:
- Never block passages to exits and hatches
- Never hinder access to safety equipment, for instance the switches to the electric system.
- Never hinder access to fire extinguishers located in a box
- Never make changes to any of the boat’s systems (especially the electricity or the fuel systems)
or allow an unqualified person to make changes to any of the boat’s systems
- Never smoke when handling petrol or gas.
5.9. Main switch and fuses
Electric circuits fuses are located beneath the main power switch and to the fuse panel which is
part of the instrumental panel. Do not change the fuse amperages or install any components that
exceed the nominal amperage of the circuit in the electric system.

In case of short-circuit current automatic fuse will trigger itself. You can “prime” it again by pressing
it back in. If the automatic fuse releases itself again you have a short-circuit in your electric system
or in some component, in which case please do contact an authorized service shop.
NOTE!
Never switch o the main switch when the engine is running! This could cause serious
damage to the engine’s electrical system.
5.10. Operation
If this is your first boat or a boat type new to you, take someone with experience from a similar boat
with you the first few times.
NOTE!
The maximum propulsion power for Yamarin 50 BR is 44,8 kW (60 hp). Do not use the boat
with bigger engine power than marked on the builder’s plate.
5.11. Controls
You will quickly learn how to control your Yamarin 50 BR, but constantly changing weather condi-
tions, like wind and waves, will always present new challenges for the driver. The remote control
combines the functions of throttle, forward and reverse gears, and the adjusting of the engine trim
angle. The boat has a hydraulic steering system.
5.11.1. Emergency switch
The emergency switch is a device with one end attached to the switch under the remote control
and the other end to, for instance, your life vest. The emergency switch automatically switches o
the engine when detached from the remote control. It is very important that the boat comes to a
halt in the event, that the driver, for whatever reason, loses his/her balance and is flung from the
helm.
NOTE!
Never take control of the boat without having attached the emergency switch to yourself.
If you attach it to your arm, do not steer the boat with that hand, because the lanyard may
twist around the steering wheel.
NOTE!
The engine will not start if the emergency switch is not attached to the switch on the re-
mote control.
DANGER!
A rotating propeller presents a life-threatening danger to a swimmer or a person that has
fallen overboard. Use an emergency switch to turn o the engine always when a swimmer
or water skier is about to re-enter the boat from the water.

5.11.2. Gearshift and throttle
The engine is put into gear by pushing the button on the gear/throttle handle upwards with your
fingers, and by pushing or pulling the gear/throttle lever forward or backward depending on which
direction you are planning to set out. When the engine is in gear, you adjust the boat speed with the
same gear/throttle lever.
When the boat is travelling forward slowly, you can use the reversing gear for braking, for instance,
when approaching the quay. Shifting into reverse must not be done if the boat is travelling at higher
speeds, because it damages the engine.
5.11.3. Adjusting of trim angle
The following are the main rules when adjusting the trim angle:
- When bringing the boat to plane, keep the “bow down” position
- When the boat is planing, and in the event, that the sea is still, the bow is lifted until you can feel
that both the engine and the boat move very easily. In calm water, the engine should normally be
trimmed up at least 3 scale marks on the trim indicator on the rev counter If engine is trimmed
up too much, the speed of the boat is reduced. If the boat is trimmed too low, both boat and
engine run heavily. To achieve good fuel economy, it is important to drive the boat with the right
engine trim angle.
- In a heavy sea lower the bow to allow it to slice through the waves better, thus providing a
smoother ride.
- In following waves, raise the bow to avoid “diving” into the waves.
WARNING!
Do not drive the boat at high speeds with the engine trimmed up (bow up) as there is
a risk of sudden heeling when the propeller hits the water again after a flight in heavy
waves. Likewise, do not drive at high speed with the engine completely trimmed down
(bow down) since this can cause the boat to pitch unexpectedly when it hits the water.
WARNING!
Waves reduce maneuverability and make the boat heel. Take this into account by reduc-
ing the speed when encountering heavier seas.
5.11.4. Starting the engine
1. Switch on the engine using the main switch.
2. Lower the engine to the driving position by pressing the Power Trim button on the gear/throttle
handle.
3. Check that the gear/throttle handle is in the neutral position and that the emergency switch is
attached to the bottom of the remote control.
4. Switch on the current, using the start key, without starting the engine and wait a few seconds
until the warning lights light up.
5. Start the engine by turning the ignition key clockwise, until it starts. If everything is correct the
engine should start within 1-2 seconds. If the engine does not start you should not “crank” the
starter engine for more than 10 seconds at any one time.
6. After the engine has started, let it idle for a few minutes before setting o. (Please refer to the
engine manual!)
For more detailed information, please refer to the engine manual.

5.11.5. Driving
It is easy to drive when the weather is fine, and the sea is calm. Do not, however, forget the impor-
tance of keeping an adequate lookout. In order, for the visibility from the driver’s seat to be as good
as possible you should:
- ensure that passengers do not restrict your visibility
- do not drive near planning speed for long periods, as the bow up comes up and reduces visibility
- when visibility is poor, look over the windshield
- remember to also keep a lookout behind you, particularly in shipping lanes and heavily tracked
routes.
NOTE!
Use proper navigation lights after dark.
Always adjust your speed to the conditions and the environment. Consider the following:
- waves (also consult the passengers about a comfortable speed)
- your own bow wake (greatest at planning speed, least at speeds under 5 knots)
- visibility (islands, fog, rain, driving against the sun)
- familiarity with the route (sucient time for navigation)
- the width of the route (other trac, noise, and wash on shore)
- make sure, that there is always sucient distance to avoid collision. Distance must be so big that
there is time to stop the boat or to take evasive action.
When running at low speed, a planning boat’s directional stability is poorer than at higher speed.
So be careful in narrow passages and when meeting other boats. It is therefore important that you
follow the international regulations on how to avoid collisions at sea = COLREG. Navigate with care
and use new or updated nautical charts.
The running position of the boat greatly aects its driving characteristics and fuel consumption.
The boat’s best operational position may be achieved by:
- placing the load properly
- adjusting the engine’s trim angle
The combination of the right operational position with the right speed also makes driving in open
waters more comfortable and safer.
WARNING!
High speed and quick maneuvering can lead to large heeling angles and loss of control
over the boat.
NOTE!
The boat is not designed to be driven through conditions that cause it to jump waves. The
warranty does not cover damage caused by air flight. By checking the engine history on
the computer, you can find out if the boat has been airborne.
5.11.6. Approaching and leaving the dock
Practice boat maneuvering skills where there is ample space to learn how to approach a dock be-
fore entering a crowded marina.
A very gentle throttle application does not generate sucient steering power. Sharp but short
throttle applications enable ecient steering movements.
19

English
Ensure that everyone on-board who does not have to stand up is seated when you are approaching
the dock. Sudden steering movements may cause the boat to sway and someone to get injured.
Before docking, prepare the ropes at stern and bow. Approach the dock bow first at a narrow angle.
Just before touching the dock, steer against the dock and shift into reverse. Apply throttle quickly
and sharply. The boat will stop and turn parallel to the dock. If possible, make the approach into
the wind or current, whichever is the strongest. This makes departing from the dock easier as the
wind or current pushes the bow out from the dock. If there is no wind or current the easiest way
to depart is by pushing the stern as far away from the dock as possible, and then slowly reversing
away from the dock into open water.
The propeller is designed to give its best grip in forward gear. Therefore, the propeller performance
is weaker in reverse. Neither does the boat have a similar steering response in reverse as in forward
gear.
WARNING!
Yamarin 50 BR is a fast boat. It does not stop instantly when at planning speed. Slowdown
in plenty of time before anchoring, beaching, or docking. Learn to estimate the distance
the boat needs before it stops. Remember that steering control is poor if there is no trac-
tion.
WARNING!
Do not try to stop the boat with your hands, and do not put your arm or foot between the
boat and the dock, the shore, or another vessel! Practice beaching and docking under
favorable conditions! Use moderate but firm engine power.
NOTE!
When you secure the boat, you must take into consideration changes in wind direction,
that the water level might rise or sink, any backwash that might occur, etc. You can get
more information from insurance companies, etc.
5.11.7. Using the canopy
The canopy is designed to take a maximum speed of 30 knots at sea, and 50 km/h in road trans-
port. All press studs must be properly fastened when using the canopy. The canopy is designed so
that it is possible to use just the front part if desired. We recommend that you remove the sides of
the canopy plus its aft part and roll the roof cover carefully and lay it down into the canopy box so
that it fits easier into the canopy box. It will work easily if you ensure that there is no fabric under-
neath the straight upper part of the canopy rail.
5.11.8. Windshield front door
Windshield middle door must always be closed and locked when driving.
WARNING!
In heavy sea, strong wind or gusts keep the door closed even in port because there is a
risk of door could be thrown by it selves. Door is heavy and it can cause a serious damage
if it hits person on board.
WARNING!
When the boat is lying still the door can get closed by a blast or when big waves hit the
boat. Because of that you are recommended to keep the door closed when no one is
boarding.
