be extremely durable and have absolute top-class handling characteristics. An Ockelbo is
built to be driven.
This Owner’s Manual is intended to help you become familiar with your new boat.
Your Ockelbo dealer will be happy to help you to maintain your boat and answer
questions concerning operation, maintenance, warranty, performance, accessories, parts
and service. Information and assistance is also available via our website

Information in this publication is based upon the latest production specifications available at
printing. AB Ockelbo Aluminiumbåtar reserves the right to make changes at any time, without
notice, in the colours, equipment, specifications, materials and prices of all models, or to
discontinue models. Should changes in production models be made, Ockelbo is not obligated to
make similar changes or modifications to models sold prior to the date of such changes. All
figures are principal only. Minor deviations between the manual, technical specifications and the
physical boat may occur as the boat is hand-built.

1. INTRODUCTION
1.1 ABOUT THIS OWNER’S MANUAL
The purpose of this owner’s manual is to help you to use your boat in a safe and
enjoyable way. The manual includes detailed information about the boat and its
equipment and accessories, as well as instructions for use and correct maintenance of
the boat. Please read the manual carefully and familiarise yourself with your boat before
using it.
At Ockelbo, we believe that you shall be free to choose a suitable outboard engine for
your specific needs. For this reason, the boat manual cannot be very detailed on engine
related topics. Often, a reference to the engine manual or other specialized components
is made. We advise you to read the engine and engine instrumentation manuals carefully,
and do not hesitate to ask for help from experts.
Likewise, the boat may have been customized or modified by another party than
Ockelbo, either when new or later in its lifetime. If your boat deviates from the data,
standard equipment and optional equipment specified in this manual, this manual alone
may not be sufficient. Please consult the party who modified the boat and any manuals
provided by them.
The owner's manual alone is not a sufficient source of information on seamanship and
boating safety. If this is your first boat or the boat type is not familiar to you, ensure
your safety and comfort by obtaining sufficient experience in handling and using the boat
before you assume the responsibilities of the boat master. Your boat dealer, local
boating clubs and national motor boat and sailing associations will provide you with more
information about local training in boating and will be able to recommend qualified
instructors.
In some countries, an operation of the craft may require a permit or authorisation, and
special regulations may apply. Your boat may also have to be registered with the proper
navigation authorities. A Declaration of Conformity is part of the documents that you
receive with the boat and it must be kept aboard with other official documents at all
times and may be mandatory when registering the boat.
This owner's manual is not a detailed service and troubleshooting guide. In case of
problems, please contact your local Ockelbo dealer. Modifications that affect the safety
features of the boat are to be performed only with the builder's written authorization.
The builder assumes no responsibility for unauthorized modifications. Always keep your
boat in good condition and make allowance for the deterioration that may occur over
time. Be careful to observe any signs of wear caused by age, heavy use or abuse. Any
boat, no matter how strong it is, may sustain severe damage if used inappropriately.
Always adjust the speed and the heading of your boat to suit the prevailing sea
conditions. Make sure the forecasted wind and sea conditions match the design category
of your boat and that you and your crew can navigate the boat in the conditions that
may arise. Wind and sea conditions for design category C range from storm to strong

1. INTRODUCTION__PAGE 4
wind with a danger of unusual waves and gusts. These are dangerous conditions that
necessitate a skilled and fit crew and a well-maintained boat.
If your craft is equipped with a life raft, study its instructions carefully. The boat must be
equipped with the appropriate safety equipment (life vests, safety harnesses, etc.) as
required for the boat type and the weather conditions. In some countries, this
equipment is compulsory. The crew must be familiar with the correct use and operation
of all safety equipment and be able to handle the boat in emergencies (including rescuing
a person who has fallen overboard, towing, etc.). Yachting schools and clubs arrange
rescue training and practice opportunities on a regular basis. Everyone aboard the craft
should wear a suitable personal flotation device (life vest or boating vest). Please note
that in some countries national boating regulations may require everyone aboard to
wear a personal flotation device whenever on board.
Finally, please pay respect to the environment by complying with good practise as well as
local, national and international (Marpol) regulations. Thank you!
Please retain this manual and provide it to the boat's next owner if you sell your
boat.
1.2 GENERAL DESCRIPTION
The boat is primarily intended for private and leisure use. The boat has a stern and aft
open deck, and a centre cabin. It is entirely made of aluminium, so are the handrails and
cleats. The boat is designed and built according to standards for CE approval in category
C and is designed to be propelled by a single outboard engine.
1.3 CRAFT IDENTIFICATION NUMBER (CIN)
The Craft Identification Number is engraved on the starboard side of the transom. See
the figure given below. The CIN must be included in all correspondence related to the
boat, such as while buying parts or registering insurance.

1.4 EXPLANATION OF SAFETY LABELS
Mounted at key locations throughout your boat and duplicated in this manual are labels
that advise the owner/operator of imperative safety precautions to follow when
operating or servicing equipment. Study chapter 3.7 to learn their location. Learn to
recognize the degree of precaution and understand the explanations of safety prior to
reading this manual. These precautions are not all-inclusive. Always follow recommended
instructions and while operating your boat.
Do not remove or obstruct any safety label.
Replace any label which becomes illegible. Replacement safety labels can be
obtained by calling your dealer.
This manual includes labels intended to highlight particularly important topics. They are
divided into 4 categories as explain below:
DANGER—Immediate hazards which with high probability will result in severe personal injury
or death if the warning is ignored.
WARNING—Hazards or unsafe practices which can result in personal injury or death if the
warning is ignored.
CAUTION—Hazards or unsafe practices which could result in personal injury, product or
property damage if the warning is ignored.
NOTE—Provides information which is important to make proper operation or maintenance.
1.5 DEALER RESPONSIBILITIES
In addition to a pre-delivery check and service of the boat, your dealer is to provide:
A description and demonstration of the safety systems, features, instruments and
controls on your boat
An orientation in the general operation of your boat
A review of all warranty information and how to obtain warranty service
The Owner Information Package
If you do not receive all these materials, or have any questions, contact your dealer.

1.6 WARRANTY
The dealer who has sold you the boat will inform you of the product warranty terms and
conditions. If for some reason such information is not provided, or any of the below
steps fail, contact AB Ockelbo Aluminiumbåtar or any Ockelbo dealer.
Registration
The boat shall be registered to ensure correct warranty management. Please contact the
dealer from whom you have purchased the boat. If that is not possible, please contact
AB Ockelbo Aluminiumbåtar or any Ockelbo dealer.
Transfer of Warranty
Please contact the dealer from whom you purchased the boat to arrange the transfer. If
that is not possible, please contact AB Ockelbo Aluminiumbåtar or any Ockelbo dealer.
1.7 INSURANCE
Boat insurance is mandatory in many countries. We recommend you to contact a
trusted insurance company in your country before taking ownership of the boat.
1.8 SECURMARK ANTI-THEFT MARKING AND TRACKING SYSTEM
To prevent theft, and to locate boats after a theft, your boat has a unique code number
which is sprayed in various places of your boat. It’s visible only by using special tools
used by the authorities. The code was added already at the factory and will enable them
to access boat and owner details from a database.
The SecurMark system requires a subscription, and Ockelbo pre-pays it for the first 12
months after registration of your ownership details. We encourage you to activate
SecurMark and, after the first 12 months of free service, continue to subscribe. You may
also mark and register your engine. Ask your dealer for help to register or if further
information is needed.

2. OPERATING THE BOAT__PAGE 7
WARNING
2. OPERATING THE BOAT
Read and make sure you understand the operation and safety topics of this owner’s manual
before you operate the boat for the first time.
2.1 SAFETY ROUTINES BEFORE LEAVING SHORE
Familiarize yourself with this owner’s manual. Always check the following items before
leaving the shore:
2.1.1 Weather and forecast
Consider the wind, waves and visibility. Are the design category, size and equipment of
your boat, as well as the skills of the skipper and crew, sufficient for the waters you are
going to? In strong winds and rough seas all portholes, doors, hatches and vents must be
closed to prevent water from getting into/onto the boat.
2.1.2 Loading
Do not overload the boat, distribute loads suitably. For stability, do not place heavy
loads high up. See chapter 3.4, 3.5 and 3.6. You can also always check the maximum
allowed loading from the CE-plate.
2.1.3 Passengers
Ensure that there are life jackets for everybody on board and instruct passengers to be
seated while the boat is in motion. Location for passengers is described in chapter 3.6.
Make sure all members of the crew understand their specific tasks, before leaving shore.
It is recommended that at least 2 passengers know to operate the boat.
2.1.4 Fuel
Check that there is enough fuel, plus a reserve tank for harsh weather etc. Look for any
fuel leaks.
2.1.5 Engine
Check the functioning and condition of steering, electrical equipment and batteries, and
carry out the routine checks specified in the engine instructions handbook.
2.1.6 Fastening of objects
Make sure everything on board is secured appropriately even in the event of high winds,
fast maneuverers and rough seas.
2.1.7 Nautical charts
If you are not navigating on totally familiar waters, ensure that you have nautical charts
covering a sufficiently large area. Even if you have a chart plotter, you should carry

2. OPERATING THE BOAT__PAGE 8
WARNING
regular charts onboard. There is always a risk for technical malfunction of electronic
devices; therefore, regular charts are also important.
2.1.8 Safety check of the boat
Check that hatches are closed and watertight.
Ventilate the stern sofa storage where the battery is installed. This is to remove
any battery gases.
Make sure that at least one person onboard knows the location of the fire
fighting equipment.
Ensure that you have an anchor with rope, emergency lights, communication
equipment, fendering ropes and a knife (to cut tangled ropes) onboard.
Check that bilge water is at the minimum, and the electrical pump is working
(test using manual operation). If water is detected, find out the reasons before
leaving the shore as excess water in the bilge indicates a water leakage.
Check the navigation lights, if you expect darkness.
Check for any leakage of water into the boat, or fuel from tanks or fuel lines.
Fuel smell or polluted water is a strong indicator of fuel leakage. Never operate
the boat with a fuel leak.
2.1.9 Inform about your route
Always inform someone on the shore about your planned route, to enable fast support
in case of problems.
2.2 EMERGENCY ENGINE SHUTDOWN SWITCH
An engine shutdown safety switch is built into the engine control; it incorporates a shut-
off switch and a lanyard. Before operating the boat, connect one end of the lanyard to
the shut-off switch while the other end to the operator (around the wrist or attached to
a hook in the life jacket).
If an emergency arises where the engine must be shut down, pull the lanyard cord to
release it from the shut-off switch, which in turn shuts down the engine. This switch is
designed to shut the engine off when the operator of the boat leaves the control station,
either accidentally by falling into the boat, or by being ejected overboard.
The lanyard should be long enough to prevent unintentional activation. Do not let the
lanyard become entangled and replace it if worn.
Wear the lanyard always when operating the boat. Use it to stop only in an emergency. DO
NOT use it to shut off the engine during normal operation. The boat may lurch heavily if
underway at high speeds, and passengers may hurt themselves or even fall overboard.

2. OPERATING THE BOAT__PAGE 9
WARNING
2.3 MAN-OVERBOARD PREVENTION AND RECOVERY
Refer chapter 3.6 for passenger and working areas of the boat.
Other areas must not be occupied when underway due to the risk of falling, potentially
into the water.
If a person has fallen into the water in calm seas, the person can use the rescue ladder
located on the port side of the transom (see chapter 7, figure 1 and position 23). Always
turn OFF the engine and then activate the emergency (dead-man) switch before using
the ladder. The ladder can be pulled down by a person already in the water. In harsh
weather, or if the person is physically not able to climb, it may be hard to use the ladder
alone and help from a person onboard may be needed. Therefore it is recommended for
two persons onboard, especially during harsh weather conditions. Chapter 4.8 further
describes MOB rescue/swim ladder.
A rotating propeller can be lethal for a swimmer or person who has fallen overboard, or a
person using the ladder to board the boat or to enter the water. Shut down the engine and
activate the emergency switch (dead man’s switch) if there is any person in the water behind
the engine, and always before using the ladder.
2.4 FIRE PREVENTION
Fire is a serious boating hazard; because boats burn quickly. Do not remain onboard and
fight a fire for longer. If the fire is out of control and cannot be put out with the fire
suppression equipment onboard, abandon ship immediately.
It is the ultimate responsibility of the boat owner to inspect and maintain the boat’s fire
prevention and fire-fighting equipment. This chapter covers fire prevention and fighting
measures related to the fuel-driven systems onboard the boat. For details of each
system/component, please refer to their specific chapters.
2.4.1 Fire extinguisher
The fire extinguisher is located underneath the port side pulpit. See the figure below and
make sure that you know how to remove and use it. The fire port (see chapter 2.4.2)
can be used for fast fighting of fires below deck.
The boat, when in service shall always be equipped with the following portable fire
extinguisher class:
Fire rating: 13A 89B C with a minimum of 2 kg capacity.
The boat owner/operator should:
1. Check the fire-fighting equipment at regular intervals; indicated on the
equipment.
2. Replace the portable fire extinguisher equipment, if expired or discharged, with
devices of same fire-fighting capacity.

2. OPERATING THE BOAT__PAGE 10
WARNING
3. Ensure that the fire-fighting equipment is readily accessible when the boat is
occupied.
4. Inform the crew members and passengers about the location and operation of
the fire-fighting equipment, the fire port, escape routes and the exits.
5. Unlock any deck hatches to enable fire fighting inside storage areas and keep
the fire port free.
6. Keep the bilges clean and check for fuel and gas vapours or fuel leaks
frequently.
1. Fire extinguisher
Never obstruct passageways to exits or hatches, obstruct safety controls (fuel valves, LPG
valves, electrical switches, etc.), obstruct portable fire extinguishers and fire ports, or allow
unqualified personnel to modify any of the boat’s systems. Keep the fire-fighting equipment
checked at the intervals indicated on the equipment.
2.4.2 Fire port
The starboard stern storage is equipped with a fire port. The port makes it possible to
detect and fight a fire below deck (bilge/tank area). The access to the fire port is through
the sofa hatch. Make sure you know its location, see the figure given below. The fire port
has a transparent cover, and an opening suitable for the fire extinguisher nozzle. In case

2. OPERATING THE BOAT__PAGE 11
DANGER
of fire inside the bilge/ below the deck area, introduce the nozzle to the fire port
opening and activate the extinguisher. Replace the fire port if worn or damaged.
1. Fire port
2.4.3 Refuelling
Before you start to fill the engine fuel tank, turn off the engine and naturally
any cigarettes or any other open flames like stoves, candles or lamps with
flames. It’s not allowed to use switches or appliances that can cause spark
formation during fuelling.
When filling the fuel tank, do not use a plastic funnel between the fuel gun or fuel
container and the boat, as it prevents discharging the electric charge difference between
the fuel pistol and the filling fitting causing a spark.
Always clean up any spillage immediately after fuelling.
Loose reserve fuel containers onboard, should be stored in one of the outside storages
in the stern, or in the aft starboard storage. Never store them inside the cabin or in the
port side stern storage, as electrical equipment may cause sparks. Always check fuel
containers before each trip to detect leakages or smell of fumes.
Fuel and its vapours are highly explosive. Exercise extreme caution and follow these
instructions while refuelling. The smell of fuel always means that there is vaporized fuel in the
boat. Never store fuel close to electric circuits or batteries (so never in the stern sofa). Do
not use plastic funnels when fuelling.

2. OPERATING THE BOAT__PAGE 12
WARNING
2.5 STARTING THE BOAT
2.5.1 Starting the engine
Read the engine owner’s manual carefully, as the boat may be equipped with several
engine brands and models.
Ensure that there are no fuel or oil leaks in or around the engine.
Check that the main power switch is turned on (for location and function, see chapter
5.3).
Make sure the engine gear shift is in the neutral position (propeller should not rotate
when the engine starts) and that the engine propeller is properly submerged in water
and away from any objects or persons.
Start the engine according to the Owner’s Manual for the outboard engine. If the engine
does not start, or functions poorly, check for instructions in the manual. If unsuccessful,
contact your engine dealer (in most cases it is your Ockelbo dealer).
2.5.2 After starting the engine
Check the cooling water control beam, to ensure that the cooling system is working
properly (visible just below the engine hood, well above water level). If water doesn’t
flow out after start, then engine overheating can cause severe engine damage.
Your engine is equipped with visual and sonic alarms for critical malfunctions such as
overheating. Read the engine manual, to understand these alarms. If the alarm goes off,
turn off the engine immediately and check the probable reason as per the manual. If the
problem continues, contact the nearest Engine Brand/Ockelbo dealer.
Do not turn off the main battery switch while the engine is running and ensure that no
exhaust fumes get inside the boat or endanger others.
2.5.3 Ensure sufficient ventilation
Toxic fumes and particles like Carbon Monoxide (CO) can accumulate in dangerous
concentrations anywhere in or around your boat while using the outboard engine or
other fuel-burning equipment. CO can remain in or around your boat at dangerous
levels even if your engine is no longer running. CO is invisible and cannot be smelled;
therefore it is hard to detect. CO can cause severe or lethal poisoning. Study the
illustration below and this text carefully:
To minimize the risk of CO poisoning, consider the following:
Make sure that there is good ventilation throughout the boat and inside the
cabin.
