FOREWORD
Congratulations on choosing a Yamarin Cross boat!
This user manual will familiarise you with the features of your new boat and help with its
care and maintenance. It has been written to help you learn to handle your boat safely and
avoid any problems. Make sure that you have received manuals for all equipment fitted on
your boat. Supplement this manual with the specifications and manuals of equipment you
purchase later for your boat. Space has been left for your own notes at the end of the
manual. Please read this manual carefully and familiarise yourself with the craft before using
it.
If this is your first craft, or you are changing to a type of craft you are not familiar with,
please ensure that you obtain sufficient handling and operating experience before
"assuming command" of the craft. This is highly important for your own comfort and safety.
Your dealer or national sailing association or yacht club will be happy to advise you of local
boating schools or competent instructors.
This user manual is not a detailed maintenance or trouble shooting guide. In case of
difficulty please contact the dealer. Always use qualified and competent people for the
maintenance, repair and modification of the boat. Modifications that may affect the safety
characteristics of the craft must be assessed, executed and documented by competent
people. The manufacturer is not responsible 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 properly. Always adjust the speed and direction of the craft to prevailing weather
conditions.
We wish You enjoyable and relaxing times on board your Yamarin Boat.

BEFORE YOU SET OFF
Familiarise yourself with this user 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 heading for? Doors and hatches must be battened down during heavy
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 underneath the aft bench. Please consider that the
stability of the boat is reduced if people stand up when on board.
Passengers
Ensure that there are personal flotation devices or lifejackets for all people on board.
Agree on the tasks each person will be responsible for during the voyage before setting
off.
Fuel and fuel system
Make 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 the remote control, and carry out the
routine daily checks specified in the engine manual.
Seaworthiness
Check the boat's seaworthiness in other respects as well: no fuel or water leaks, safety
equipment 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 are held in place also during
rough seas and high winds. Please note that the seat cushions may fly over board if they
are not fixed properly with press studs.
Nautical charts
If you are not 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 unfasten which mooring line, etc. Make sure that the
mooring lines will not get entangled with the propeller during manoeuvring.
Obligatory equipment
What is considered obligatory equipment varies from country to country. Find out what
is required for your boat.
You will find additional instructions concerning the engine in the separate engine manual.

1 General
The user manual will help you familiarise yourself with the properties and features, as well
as the care and maintenance of your new boat. Separate manuals for installed equipment
are attached and are referred to in many sections of the user manual. You can supplement
this owner’s 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 CINcode 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 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.

The boat and its factory-installed equipment have a two-year warranty, starting from 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.
11 (42)
4 Before use
4.1 Registration
Registration regulations vary from country to country.
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!
4.3 Training

5 Characteristics and use of your boat
5.1 General
This user manual is not meant to be a complete service or repair manual, but to guide the
user in using his/her boat in a proper way.
Pictures and drawings of this manual might include optional or country-specific features.
5.2 Basic data
Recreational crafts can be constructed according to 4 categories (A, B, C and D)
according to recreational craft directive 2013/53/EU. This boat has been
constructed according to design category C, which denotes the following:
The boat is built for conditions where the wind reaches a maximum of 6
Beaufort (approx. 14 m/s) and corresponding seas (significant wave height at
most 2 metres). Such conditions may be encountered on exposed inland
waters, in estuaries, and in coastal waters in moderate weather conditions.
Significant wave height is the mean height of the highest third of the waves,
which approximately corresponds to the wave height as estimated by an
experienced observer. Individual waves may reach up to twice this height. If
the significant wave height is 2.0 m, the mean height of all waves is roughly 1.2
m.
Maximum recommended load: See technical specification.
Please also refer to section 5.4, ”Loading”.
Main dimensions and capacities: See technical specification.
Craft length, width, draught, total weight etc., as well as tank capacities are
shown in the technical specifications.
Builder's plate:
Part of the previously mentioned information is given on the builder's plate,
which is affixed next to the remote control. Supplementary information is
provided in the appropriate sections of this manual.

NOTE! If you load the boat from stern to bow, you will have better fuel
economy.
16 (42)
5.4 Loading
The boat's maximum permitted load is 490 kg. This load includes the following weights:
a) 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).
b) And liquids (fuel) in tanks 40 kg.
NOTE! The maximum load only includes the above-mentioned weight
components.
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. Always avoid placing heavy items high up.
5.5 Engine and propeller
The greatest engine power recommended for the boat is 60 hp (44,8 kW). The construction of
the boat is not designed to bear more power than 60 hp. Manoeuvring the boat can be very
dangerous if the boat has an engine bigger than 60 hp. The warranty is not valid if the boat is
used with more power than 60 hp. Follow the dealer’s instructions when choosing the
propeller for your craft.

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
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.
17 (42)
1. Rainwater drainage valve
2. Maintenance hatch of drainage pump (pump is an optional accessory)
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! 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!
1. The shut-off flap
2. Drain plug
3. Rainwater drainage valve
NOTE! Make sure that water can flow unobstructed through the
drainpipe. Debris like 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.
18 (42)
NOTE! There is always some amount of condensed water in the bilge. A
small amount of water may also come through the hull bushings,
especially as the boat ages. 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 off. Water in the
bilge can be drained through this maintenance hatch, using a
separate, pipe-model drainage pump (optional accessory). Have
possible 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! In rough weather, the hatches and drawers should be kept shut to
prevent them filling with water.
5.6.2 Stability and buoyancy
Please note that the boat's stability is 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.
The amount of water in the bilge must be kept as low as possible.
The boat's stability may be impaired during towing, or when passengers are lifting heavy
items.
The boat will carry its passengers also when filled with water.
5.7 Avoiding the risk of fire or explosion
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.
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 gasified 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, if moved, could prevent fuel flow to the
engine. This is particularly important for items that may press against hoses or the fuel filter.
Check annually that the fuel hoses are not worn, especially at lead-ins.
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 tank.
19 (42)
WARNING! Gasified fuel is highly explosive. Observe these instructions and
the utmost caution during refuelling. The smell of fuel always
means that there is gasified fuel on your boat.
5.7.2 Fire protection
The boat is equipped with a portable 2 kg fire extinguisher class 8A 68 B, which is the
minimum power requirement for extinguishers. The extinguisher is located in the storage
compartment on the front of the co-driver's console (the battery compartment). The boat
must always have an approved and inspected extinguisher during use. The fire extinguisher
must be inspected annually by an authorised inspector to ensure its functioning. In the event
that the fire extinguisher is replaced, the capacity of the new one must be at least equivalent
to the old.
Location of 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.
NOTE! In a new boat the fire extinguisher might go out of date in a short
period of time.
20 (42)
Remember:
- 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 while handling petrol or gas.
NOTE! Always keep the bilge clean and regularly check for possible fuel
leaks.
5.8 Main switch and fuses
Electric circuit fuses are located beneath the main power switch. Do not change the fuse
amperages or install any components that exceed the nominal amperage of the circuit in the
electric system.
Operation of the main switch:
- clockwise position -> circuit switched on
- counter-clockwise position -> battery disconnected
Main switch and fuses.
F1= Navigation light fuse
F2 = The 12 V socket fuse
21 (42)
All fuses on the boat are automatic. In the event of a fault current, the automatic fuse will
blow. You can "rearm" the fuse by pushing it back in. If the fuse immediately blows back out,
there is a short-circuit in the electrical system or a component. You must leave repairing the
boat's electrical system to a professional electrician.
NOTE! Never switch off the main switch while the engine is running!
It can cause serious damage to the engine’s electric system.
NOTE! Never install electric equipment on the boat with the power
switched on.
NOTE! Use the Extra circuit when installing additional equipment on the
boat. Connect the appliance both to the power supply and
grounding cables. Never use the hull of the boat as a grounding
network.
NOTE! When connecting or disconnecting the battery, do not touch both
terminals, or a terminal and the hull of the boat simultaneously
with metal objects.
5.9 Operation
If this is your first boat or a boat type new to you, take someone with experience of a similar
boat with you the first few times.
NOTE! The boat's maximum propulsion power is 44,8 kW (60 hp). Do not
use the boat, if its engine has a higher power than the one
marked on the builder's plate.
5.9.1 Controls
You will quickly learn how to control your boat, but changing weather conditions, such as
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.
5.9.2 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 example, your life vest. The emergency switch
automatically switches off the engine when detached from the remote control. It is very
important that the boat will come to a halt in the event that the driver, for whatever reason,
loses his/her balance and is flung from the helm.
22 (42)
NOTE! Never take control of the boat without having attached the
emergency switch to yourself. If you attach the emergency switch
to your arm, do not steer the boat with that arm, because the
emergency switch cord may be tangled in the steering wheel
during tight turns.
NOTE! The engine will not start if the emergency switch is not attached
to the switch on the remote control.
DANGER! A rotating propeller presents a life-threatening danger to a
swimmer or a person that has fallen overboard. Always use the
emergency switch to turn off the engine when a swimmer or
water skier is about to re-enter the boat from the water.
5.9.3 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 the direction in which you are planning to set out. When the engine is in gear,
you can adjust the boat's speed using the same gear/throttle lever.
When the boat is travelling forward slowly, you can use the reverse gear for braking when
approaching the pier, for instance. You must not shift into reverse if the boat is travelling at
higher speeds, because it will damage the engine.
5.9.4 Adjusting the engine 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 seas are clam, keep lifting the bow until you can feel
that both the engine and the boat move very easily. In calm waters, the engine
should normally be trimmed up at least 3 scale marks on the trim indicator on the
revolution counter. If the engine is trimmed up too much, the speed of the boat will
be reduced. If the boat is trimmed too low, the boat will run slowly and the engine
will run heavily. To achieve good fuel economy it is important to drive the boat with
the right engine trim angle.
- In heavy head seas lower the bow to allow it to slice through the waves better, thus
providing a smoother ride.
- In following seas, raise the bow to avoid "diving" into the waves.
- Adjust the engine trim angle slightly upwards while reversing to make the engine run
higher in the water.
23 (42)
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 the bow hits the water.
WARNING! Waves reduce manoeuvrability and make the boat heel. Take this
into account by reducing speed when encountering heavier seas.
5.9.5 Starting the engine
1. Switch the power on 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 for the warning lights to light up.
5. Start the engine by turning the ignition key clockwise, until it starts. If everything is in
order, the engine should start within 1-2 seconds. If the engine does not start, you
should not try to start it for more than 10 seconds at a time.
6. After the engine has started, let it idle for a few minutes before setting off. (Please
refer to the engine manual!).
For more detailed information, please refer to the engine manual.
5.9.6 Driving
It is easy to drive when the weather is fine and the sea calm. However, always remember to
keep an adequate lookout. In order to maintain the best possible visibility from the driver's
position, you should:
- Ensure that passengers do not restrict your visibility.
- Not drive near planing speed for long periods, as the bow will come up and reduce
visibility.
- Look over the windshield when visibility is poor.
- Remember to also keep a lookout behind you, particularly on shipping lanes and
heavily trafficked routes.
NOTE! Use navigation lights in darkness.
24 (42)
Always adjust your speed to prevailing conditions and the environment. Take into account
the following:
- waves (also consult the passengers on what is a comfortable speed)
- your own bow wake (greatest at planing speed, least at speeds under 5 knots)
- maintaining adequate lookout
- visibility (islands, fog, rain, driving against the sun)
- knowledge of the route (time required for navigation)
- rules of priority (other traffic)
- width of the route (other traffic, noise and bow wake near shore)
- Make sure to always maintain a sufficient distance to avoid collision. The distance
must be sufficient to stop the boat or to take evasive action.
When running at low speed, a planing boat's directional stability is poorer than at higher
speeds. So be careful in narrow passages and, particularly, when meeting other boats
and 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 affects its handling characteristics and
fuel consumption, as well as visibility from the driver's seat. You can affect the running
position by:
- Placing the load properly. The general rule is that you should place as little weight in
the bow as possible.
- adjusting the trim angle.
The combination of the right running position with the right speed also makes driving in
rough seas safer and more comfortable.
WARNING! A high speed and sudden manoeuvring can lead to loss of control
over the boat and large heeling angles.
WARNING! The boat is not designed for use in temperatures below 0°C. The
drainage system will freeze and cease to operate as designed.
NOTE! The boat is not designed to jump waves.
The warranty does not cover damage caused by flight. It is
possible to check whether the engine has been airborne from the
engine history on the repair shop's computer.
5.9.7 Approaching and leaving the pier
Practise boat manoeuvring skills where there is ample space to learn how to approach a pier
before entering a crowded marina.
A very gentle application of throttle does not generate sufficient steering power. Sharp but
short throttle applications enable efficient steering movements when approaching the pier.
25 (42)
Ensure that everyone on board who does not have to stand up is seated when you are
approaching the pier. Sudden steering movements may cause the boat to heel and injure
somebody.
Before docking, prepare the mooring lines at stern and bow. Approach the pier bow first at a
narrow angle. Just before touching the pier, steer against it and shift into reverse. Apply
throttle quickly and sharply. The boat will stop and turn parallel to the pier. If possible, make
the approach into the wind or current, whichever is the strongest. This makes departing
easier as the wind or current will push the bow out from the pier. The easiest way to depart
is to first push the stern as far away from the pier as possible, and then slowly reverse away
from the pier into open water.
The propeller is designed to have the best grip in forward gear. Therefore, propeller
performance is weaker in reverse. Neither does the boat have a similar steering response in
reverse as in forward gear.
WARNING! The boat is fast. It will not stop instantly from plane. Slow down in
time before anchoring, beaching or docking. Learn to estimate the
distance the boat needs to come to a halt. Remember that
steering control is poor if there is no traction.
WARNING! Do not try to stop the boat with your hands, and do not put your
arm or foot between the boat and the pier, shore or another
vessel! Practise beaching and docking under favourable
conditions! Use moderate but firm engine power!
NOTE! When securing your boat, you must take into consideration
possible changes in wind direction, a rise or lowering of the water
level, any possible bow wakes, etc. You can get more information
from your insurance company, for example.
5.9.8 Canopy use (optional accessory)
The canopy is designed to withstand a maximum speed of 30 knots at sea and 50 km/h in
road transport. All press studs must be properly fastened when using the canopy. We
recommend that you remove the sides and back of the canopy to make it fit into the canopy
box more easily. Then, fold the upper parts of the sides entirely on top of the roof, so that no
fabric remains where the corners of the canopy supports are. Finally, roll up the roof part
along with the sides folded on top of it, and lower the canopy into the canopy box.
NOTE! The windshield and canopy do not necessarily form a watertight
seal. Water may enter the boat between the canopy and
windshield when the canopy is up.
26 (42)
5.9.9 Doors between the windshield and steering console
Doors must always be kept shut and locked while driving.
WARNING! Large waves or gusts of wind may slam the door shut also when
the boat is stationary. It is thus recommended to always keep the
door closed when passage through the bow deck is not being
used.
5.10 Proper use – other recommendations and guidelines
5.10.1 Man overboard
It is always a serious situation when someone falls overboard. Rescue procedures should be
practised in advance during good weather, because it is too late for practice when someone
has fallen overboard.
The boat is equipped with the fixed swim ladder that can be lowered down from the water.
The swim ladder unfolds to the full length by pulling the extension ladder away from the
boat.
It is always easiest to help a person climb on board from the water at the stern of the boat. A
rope loop attached to the boat helps lifting. The boat’s swim ladder extends 30 cm into the
water.
It is very important to maintain visual and verbal contact with a person that has fallen
overboard.
DANGER! A rotating propeller presents a life-threatening danger to a
swimmer or a person that has fallen overboard. Always use the
emergency switch to turn off the engine when a swimmer or
water skier is about to enter the water or re-enter the boat from
the water.
5.10.2 Securing loose equipment
Secure all heavy equipment, such as anchors, firmly in place before setting off.
27 (42)
5.10.3 Respect for the environment
Conservation of the environment is a matter of honour for every boater. Therefore, you
should avoid:
- fuel and oil leaks
- emptying garbage and waste into the water or on the shore
- letting detergents or solvents get into the water
- loud noise both on the water and at the marina
- and producing an unnecessarily high bow wake, especially in narrow passages and
shallow waters.
Service the engine well and run it at the most economical speed, which will also keep
exhaust emissions low.
Please also consider other local environmental legislation and regulations.
Please make sure to familiarise yourself with the International Convention for the
Prevention of Pollution From Ships (MARPOL) and respect it to the greatest possible extent.
5.10.4 Anchoring and mooring the boat
Always moor your boat carefully, even in sheltered places, because conditions can change
rapidly. Mooring lines should be equipped with absorbers to dampen any jolts. Please refer
to the section on towing for the location of bollards. To prevent abrasion, use fenders that
are large enough.
The hook located at the bow of the boat is for locking the boat to trailer. The hook on the
deck is for locking the boat (e.g. to a pier). The locations of the hooks are presented in
Paragraph 8.
NOTE! Make sure that the lock or chain does not scratch the deck of the
boat.
The endurance of the bow bollards forward and the aft bollards backward is at least 12.6 kN,
which is approximately 1,300 kg. The ultimate strength of ropes should not exceed 1,300 kg,
so that the rope will break before the bollard or its fastening does.
The minimum anchor weight for the boat is 5 kg. Drop anchor far enough from shore. A
moderate grip is attained if the anchor line length is 4–5 times the water depth.
WARNING! Do not try to stop the boat with your hands, and do not put your
arm or foot between the boat and the pier, shore or another
vessel!
NOTE! When securing your boat, you must take into consideration
possible changes in wind direction, a rise or lowering of the water
level, any possible bow wakes, etc. You can get more information
from your insurance company, for example.
28 (42)
NOTE! It is the owner's / user's responsibility to make sure that the
boat's mooring and anchoring equipment is suitable for the boat's
intended use.
5.10.5 Towing
When towing another boat, use a floating line that is strong enough for the task. Begin
towing carefully, avoid jerks, and do not overload the engine.
The owner of the boat should consider the measures necessary for securing the boat’s
towrope.
If you are towing, or if your boat has to be towed, attach the towline to the bollards as per
the following image.
Attaching the towline to the bollards.
WARNING! When towing, the towline is under high tension. If it should break,
the end that has snapped off may lash back at fatal speed. Always
use a thick enough rope and avoid the line of the towrope.
NOTE! When towing another boat or being towed, always drive at low
speed. If the boat has a displacement hull, never exceed hull
speed while towing (speed before boat rises to plane).
NOTE! The towline should always be fastened so that it can be
unfastened under load.
5.10.6 Trailer transport
Weight information for trailer transport can be found in the technical specifications. The
trailer's keel supports should carry most of the weight of the boat. Adjust the keel supports
so that the boat cannot slide from side to side. For more information on correct support and
trailer size, please turn to your dealer.
Clean the supports of sand and dirt, so they will not scratch the bottom of the boat. Doublecheck that the trailer is securely coupled to the trailer tow hitch!
29 (42)
The place for lifting the boat out of the water should be sheltered, and the ramp should
extend deep enough into the water. Reverse the trailer so deep that the rearmost keel
support is just above the water. Drive the boat carefully towards the rearmost keel support
and fasten the winch cable to the trailer hook.
Reel the boat up onto the trailer, taking care that the boat remains straight on the trailer's
centre line. Remember to trim up the engine before reeling the boat onto the trailer, so it
will not hit the bottom.
Attaching the boat to the trailer.
Tie the boat properly before beginning transport. The sling ropes at the bow should be
directed down and back, and the sling ropes at stern should be directed down and front. Do
not leave any loose equipment or extra load on the boat when it is being transported.
Remove the seat cushions and close all hatches properly.
The engine should be in the driving position during transport. However, ensure that there
remains adequate clearance. If the clearance is not sufficient in this position, you can
transport the engine raised. In such cases, lock the engine in the up position.
Wash the boat immediately after transport. Take special care when washing an aluminum
hull if the roads have been salted. Road salt can leave permanent marks on an aluminum hull
if it is not washed off. If the boat is kept on the trailer between transports, you must loosen
the sling ropes for the duration and only tighten them before the next transport.
NOTE! NOTE! The trailer should be slightly front-weighted. Appropriate
nose weight is 4 % of the total mass of the trailer, but not less
than 25 kg. Nose weight must not exceed the maximum vertical
load on tow ball. Maximum load is defined by the manufacturer of
the towing vehicle. Make sure that the boat is fastened tight
enough to the trailer, and that the weight of the boat is divided
equally between side supports. If the boat swings against a side
support during transport, it can result in hull damage.
When letting the boat down from the trailer, remember to fasten the bow rope to the boat
beforehand so that you can release the cable from the trailer hook as soon as the boat is in
the water. Be careful with the winch handle!
30 (42)
5.10.7 Docking
A storage cradle should be sufficiently steady and suitable for the boat's and engine's
dimensions. A sturdy plank (2x4"), should be placed between the "V" trestles to support the
keel and to bear most of the weight of the boat. The boat must not rest on the side
supports. The side supports should not be placed touching the bottom chine, and point loads
should be avoided. The supporting structures should be strong, particularly near the
transom, to support the added weight of the engine. Storage cradle dimensions are shown in
the picture below.
Storage cradle dimensions.
Only use reputable lifting companies or boat yards with sufficient
lifting capacity. In addition to the boat's tare weight (please refer to the technical
specification), also take into consideration accessories and other possible loads in the boat.
When the boat is being lifted, the lines must be placed under the boat and the boat must
remain horizontal during lifting.
NOTE! The boat must not be lifted by its bollards.
DANGER! Never stand under a boat that is suspended from a crane.
31 (42)
6 Servicing and maintenance
Keep your boat and its equipment clean and tidy. This increases comfort and safety on
board, as well as the boat's resale value.
Familiarise yourself with the service procedures shown in the engine manual (see annex).
Carry out the procedures carefully, or ensure they are performed by an accredited service
company
6.1 Washing and waxing the boat
Cleaning fibreglass surfaces
Normally it is sufficient to just wash and wax the deck and sides. Special boat cleaning agents
are most suitable for the purpose. Do not use strong solvents; they can cause glossy surfaces
to fade. Mildly abrasive polishes can be used to remove chafes and embedded dirt from the
deck. The boat's aluminum and fibre glass surfaces can be washed with a pressure washer.
Observe the chemical manufacturer's instructions when washing and cleaning the deck.
Useful tip: Washing the boat will be easier if it is done immediately after
getting the boat out of the water.
NOTE! Do not spray water with a pressure washer on the caulking seam
under the rubbing strip. Pressurised water can damage the glued
seam.
NOTE! Do not spray water directly on the boat's air grills, or the water
may penetrate the boat's interior and structure.
The hatches of the glove compartment and instrument panel are made of plastic and can be
washed with soap water; never use solvents to clean them.
Cleaning the aluminum hull
The hull should be washed with a special aluminum cleaning agent.
Remember to dry the boat.
The waterline and bottom of the boat must be washed in temperatures of at least +10 °C,
and only after the hull is completely dry.
Protecting the aluminum hull
When the aluminum hull is completely clean and dry, it can be protected against oxidation.
Oxidation is a natural reaction of aluminum against corrosion and does not affect the boat's
quality.
32 (42)
Useful tip: When the boat has been washed with tap water, a thin chalk-like
layer of lime and minerals will remain on the boat’s surface after
it has dried. The problem can be eliminated by adding a few drops
of pine oil soap into a bucket of rinsing water, which will soften it.
Useful tip: Water and lime stains on stainless steel rails and handles
disappear when you apply some Lemon Pled furniture spray.
Useful tip: If the boat's ropes smell bad after the season, immerse them for a
couple of hours in a bucket of water with a bottle of apple vinegar
and a splash of fabric conditioner added. Allow the lines to dry
properly, and they will be as good as new.
NOTE! Make sure that the cleaning, polishing and protective agents you
use are suitable for aluminum and the other surfaces you will
treat with them. Always follow the chemical manufacturer's
instructions.
6.2 Care instructions for seat cushions
Always use the canopy or harbour cover when it is raining. Although the seat cushions are
made of water-resistant material, water can get in through their seams. If the cushions
remain damp for any length of time, they may get mouldy and be ruined. If the mattresses
get wet, the fabric can be removed by unzipping the mattress and dried, for instance, in the
sun, at room temperature or in a sauna (max + 50 °C). The warranty does not cover cushions
spoilt by rain or damp.
NOTE! To keep the seat cushions in good condition over the winter, they
must be stored in a dry and well-ventilated place.
NOTE! Wet cushions should not be placed in storage, because they
gather mould.
The press studs of the seat cushions should be sprayed with silicon vaseline every now and
then; otherwise, they may become so tight that the fabric will tear when trying to open
them. The warranty does not cover ripped seat cushions. Use very little silicon vaseline at a
time in order not to stain the cushions.
6.3 Care instructions for the canopy (optional accessory)
Store the canopy over winter in a dry and well-ventilated place. The press studs of the
canopy should be sprayed with silicon spray every now and then, otherwise they may
become so tight that the canopy will tear when trying to open them. The warranty does not
cover a torn canopy.
33 (42)
6.4 Care instructions for the windshield
The boat's windshield is made of acryl, and can be washed with water and soap (e.g. car
shampoo). Do not use solvents to clean acryl.
Useful tip: When wiping the boat's windshield dry after cleaning, avoid using
circular motions. This can leave circular smudges on the
windshield that become visible in sunlight, impeding visibility.
Wipe off any streaks with dry newspaper or cotton cloth
using first horizontal, then vertical motions. Repeat this a few
times and you'll bring the windshield to a brilliant shine.
6.5 Care instructions for the stainless steel components
To keep the boat's stainless steel parts, such as rails, handles and bollards, shining as good as
new, the boat's owner should keep the parts clean and waxed. The edges of the mounting
flanges of the rails should also be cleaned. Any dirt that remains under the edge of the
flange will begin to look like rust. In regular use (i.e. no damage), the parts should be cleaned
and waxed at least twice every summer. The rails should also be cleaned and waxed in
autumn, when the boat is put into winter storage.
6.6 Care instructions for the remote control
Normally, the remote control needs no other maintenance apart from greasing and
calibration during winter servicing. If the remote control becomes stiff for any reason, it
needs to be serviced immediately.
6.7 Care instructions for the steering system
The Yamarin Cross 49 BR has cable steering, which normally does not require other servicing
apart from greasing and inspection during annual maintenance. If steering seems stiff or
keeps catching, it must be serviced immediately.
6.8 Care instructions for electrical components
Electrical components like main switches, other switches and couplings do not normally
need to be serviced if the boat is stored in a dry and well-ventilated place for the winter. If,
however, you wish to protect electrical components against oxidation, the best way to do it
is by spraying them every now and then with a moisture repellent antioxidant.
34 (42)
6.9 Minor superficial repairs
You can repair minor surface damage to the boat's deck yourself. However, achieving a neat,
unnoticeable repair requires a considerable amount of skill:
1. Protect the area around the damage with tape.
2. Bevel the edges of the damaged area and clean with acetone.
3. If the damage is deeper than 2 mm, it is advisable to smooth it with an appropriate
polyfiller before painting.
4. Mix topcoat with 1.5-2 % hardener.
5. Fill the repair with more topcoat than needed, so that its surface remains slightly
proud of the surrounding area.
6. Carefully put tape over the repair.
7. After the topcoat has hardened, remove the tape and sand the repair using 600 and
1200 paper applying water.
8. Buff using abrasive paste and wax.
The colours used on this boat are specified in the technical specifications. One point to
consider is that a paint called gelcoat has been used in manufacturing the boat, but the
surface is always repaired with a paint called topcoat. Gelcoat paint does not harden without
a mould surface, whereas paraffin has been added to topcoat to allow it to harden.
WARNING! Be careful when handling the hardening agent. If the hardening
agent vessel/bottle leaks, or if hardener falls on, e.g., a dirty floor
or rag, there is a very high risk of fire. Do not throw rags or vessels
containing topcoat/hardener mixture into the rubbish bin. Always
use eye protection when handling topcoat or hardener. If you get
hardener in your eyes, rinse your eyes immediately with tap water
and see a physician.
NOTE! Post-delivery installations and alteration work may cause damage
to the structure of the boat or impair safety if not performed
correctly. Please contact the dealer if you are planning any
modifications.
NOTE! It is important to use aluminum or stainless steel screws and
rivets when installing accessories. There are ready-made fittings
for a depth finder sensor (Garmin) on the boat's transom.
NOTE! When installing accessories on an aluminum surface (except in
their pre-ordained places), always use aluminum rivets and
insulating washers to avoid corrosion.
35 (42)
7 Winter storage
Preparing your boat for winter storage is an annual routine. Have your boat lifted in good
time before the water freezes. Your boat is not designed for use in ice and it is not meant to
be used in temperatures below zero (for example, the rain water draining system will freeze
up). It is advisable to perform all maintenance, repair and inspection procedures in
connection with placing the boat in winter storage.
Familiarise yourself with the service procedures shown in the engine manual. We
recommend that you leave them to an authorised service agent. Do not forget to service the
remote control and steering system. Make sure to perform their maintenance according to
their separate instructions and manuals.
7.1 Measures before winter storage
Have your boat lifted in good time before the water freezes. Your boat is not designed for
being driven in ice, or for remaining in the water when it freezes.
Wash the bottom of the boat immediately after the boat has been lifted. Algae and slime will
come off easier if they are not left to dry.
Give the engine and other equipment their winter servicing, following their separate
manuals. If your boat is stored outside or in a humid place over the winter, empty it of
textiles and other equipment that may corrode or become mouldy in damp conditions. Wash
the ropes in fresh water. Replace any worn ropes. Leave bushing valves open. Remove the
drain plug for the winter.
Electronic instruments are best protected against oxidation and theft by detaching them and
removing them to a dry indoor environment for the winter. Detach the batteries and store
them in a warm, dry place. Charge the batteries at least twice during the winter. Spray the
couplings of the electrical system with an appropriate water repellent antioxidant.
Always cover your boat so that water or snow cannot collect inside. Always make sure,
however, that it is adequately ventilated. A winter storage cover is available as an optional
extra for your boat.
NOTE! Make sure that the winter storage cover or its ropes do not touch
the aluminum hull. If the cover or its ropes abrade the hull, they
will leave black marks on it.
36 (42)
7.2 Measures before launching the boat
Repair possible damage to the gelcoat surface according to section 6.9.
In coastal areas, antifouling paint should be used to prevent the hull from becoming covered
with vegetation. Fouling of the bottom and, especially, the propeller increases fuel
consumption remarkably. However, if the boat is anchored at the inlet of a stream, in a landlocked lake, or if it is lifted out of the water at least once every two weeks, it is normally not
necessary to use antifouling paint. Carefully follow the paint manufacturer’s instructions
when applying the paint. When sanding old antifouling paint, remember that the dust is
toxic. Antifouling paint is not necessary in lake areas.
NOTE! Do not apply any paint to the zinc anodes, depth finder sensor, or
the piston rods of the hydraulic trim tabs. Do not apply paints
containing copper or lead on aluminum parts and remember to
follow the paint manufacturer’s instructions. The warranty does
not cover damage caused to the hull by antifouling paint
containing lead or copper.
Useful tip: Do not throw away a used paint brush. A hardened antifouling
paint brush can be reused if you first soak it for a couple of hours
in a mix of 2 litres of hot water, 100 ml of vinegar, and 50 ml of
baking powder.
Perform the necessary service procedures required for the engine according to the engine
manual. Check the functioning of electric equipment and remove possible oxidation from
fuse connectors etc.
Remember that petrol goes stale over time, and you must always start the engine with fresh
petrol in the spring.
When the boat has been launched you should open all hull bushings and check to ensure
that there are no leaking hoses or connectors. The locations of the through fittings are
presented in Chapter 5. Bring your safety equipment back on board before setting out.
37 (42)
8 Lay-out
8.1 General lay-out
1. Trailer hook
2. Hook for locking the boat
3. Navigation light
4. Light mast
1. Rainwater drainage valve 5. Main switch
2. Glove compartment 6. Fuse panel
3. Fire extinguisher 7. Bilge compartment inspection hatch
4. Battery (not standard equipment)
WARNING! Handle the boat’s hatches with care and watch your fingers and
toes.
38 (42)
8.2 Fuel system
Smaller Yamarin boats use detachable fuel tanks. The detachable tank is normally delivered
together with the outboard engine. Yamarin boats have spaces for two detachable tanks.
Fuel hoses are usually attached to detachable tanks with quick release couplings, so
detaching the tank and filling it at a service station while the boat remains in the water is
quite convenient (please refer to the section "Refuelling").
Detachable tanks are also usually equipped with displays that indicate the amount of
remaining fuel, and ventilation valves, which you should remember to open when the engine
is being used, to remove pressure from the tank and ease fuel intake.
8.3 Steering system
The Yamarin Cross 49 BR is equipped with cable steering.
The steering cable's length is 3.6 metres (12 feet).
NOTE! If you want to replace a component in the steering system, please
note that all components must conform to the ISO 10592
standard and carry the CE mark.
8.4 Electrical system
The Yamarin Cross 49 BR's electrical system contains the following main components:
1. Wire harness
2. Main switch
3. 1 pcs switches
4. 12V outlet
5. Navigation lights
In addition, the engine is an essential part of the boat's electrical system, which functions
both as a power source and a consumer of power.
Switch off the main switch when leaving the boat for a long period of time. Remember also
to switch off the main switch before making any electrical installations.
If you connect or disconnect the battery, take care not to touch both battery terminals with
a metal object at the same time. Please remember to observe caution in other respects as
well if you have to charge the battery with a separate charger, Recharging with an overly
large current creates a risk of explosion.
Do not alter the onboard electric system or relevant drawings; alterations and maintenance
work have to be carried out by a professional.
