INTRODUCTION
Welcome!
You have just been delivered your new BENETEAU boat and we thank you for the confidence you have shown in us by
ordering from our brand. The whole BENETEAU team welcomes you on board.
A BENETEAU is made to last and to bring you all the pleasure you should expect from a boat over a period of many years.
Each boat is subject to the utmost attention to detail from the design stage right through to launching.
This manual is designed to help you to enjoy your boat comfortably and safely. It includes the boat's specifications, the
equipment provided or installed, information on the boat's systems and some tips on operation and maintenance. Some
of the equipment described in this manual may be optional.
Your BENETEAU dealer will be able to help and advise you on the use and maintenance of your boat.
The first time you use your boat a high level of skill and attention will be required. The proper functioning of all equipment
will depend on the initial set-up being carried out correctly. For this reason the first launch must be carried out under your
dealer's supervision.
Read this Owner's Manual carefully and take time to get to know your boat before you use it.
The better you know your vessel, the better your experience will be when sailing it.
Keep this manual somewhere safe and pass it on to the new owner should you sell your boat..
You are advised to keep any user's guides supplied by the manufacturers of any equipment for your boat
(accessories, etc.), together with your manual.
For each piece of equipment on your
boat,please read the instruction manuals
provided by the manufacturer.

This manual is written to help you enjoy your boat in safety. It contains details of the boat and of all the equipment provided and installed on your boat, as well as instructions
for its use. Read it carefully and get to know your boat properly before using it.
This owner's manual is not in any way a navigation or mariner's training manual. If this is your first boat or if you have changed to a type of boat with which you are not
familiar, make sure that you learn how to use it and manoeuvre safely and with ease before taking the helm alone. Your dealer, national sailing or motorboat association, or yacht
club will be very happy to tell you about navigation schools or qualified instructors in your area.
Make sure that the wind and sea conditions forecast are appropriate for the design category of your boat and that you and your crew are capable of manoeuvering the boat
in these conditions.
Even with a well-adapted boat, the wind and sea conditions which correspond to the design categories A,B and C range from storm force winds for category A to severe
storm conditions at the upper end of category C, and could put the boat at risk from very large waves and strong gusts. These are dangerous conditions in which only an
experienced, fit and well-trained crew, manoeuvring a well-maintained boat, will be able to navigate with sufficient skill.
This owner's manual is not intended as a detailed maintenance or repairs manual. Should any problems arise please contact your dealer. If a maintenance manual is
provided, please use it.
Always use the services of an experienced professional for the maintenance of your boat, for fitting accessories and for any modifications. Any alterations which may affect
the safety specifications of the boat must be assessed, carried out and recorded by persons qualified to do so. The boat manufacturer cannot be held responsible for any
modifications not approved by them.
Some countries require you to hold a Certificate of Competency or other such qualifications, or there may be other specific regulations in force.
Always maintain your boat well and make note of any deterioration due to wear and tear or to heavy or inappropriate use.
Any boat – no matter how well-built – could suffer serious damage if used recklessly. This kind of use is highly unsafe. Always adjust the speed and heading of your boat
according to the sea conditions.
If your boat is equipped with a life-raft, read the instruction manual carefully. The crew must have all safety gear available onboard (lifejackets, harnesses etc.), and this
must appropriate for the type of boat and for the weather conditions. In some countries it is mandatory to have this safety equipment onboard. The crew must be fully familiarised
with the use of the safety gear and with emergency manoeuvres (man overboard procedures, towing another vessel etc). Sailing schools and clubs regularly run training sessions
for these skills.
It is strongly advised that everyone wears an appropriate flotation device (lifejacket or personal buoyancy aid) when on deck. Be advised that in some countries it is
mandatory to wear a flotation device which meets the national regulations at all times.

2.4 DESIGN CATEGORIES
Category A:
A yacht of design category A is considered to be designed for wind that may exceed force 8 (on the Beaufort scale) and waves that can exceed a significant height of 4 metres,
but excluding exceptional conditions such as storms, severe storms, tornadoes and extreme sea conditions or very large waves.
Category B:
A yacht of design category B is considered to be designed for wind that may go up to force 8 inclusive and waves that can reach a significant height up to 4 metres inclusive.
Category C:
A yacht of design category C is considered to be designed for wind that may go up to force 6 inclusive and waves that can reach a significant height up to 2 metres inclusive.
Category D:
A yacht of design category D is considered to be designed for wind that may go up to force 4 inclusive and waves that can reach a significant height up to 0,3 metres inclusive,
with occasional waves of a maximum height of 0,5 metres.
NOTE: Boats in each category must be designed andbuilt to withstand these parameters in respect of stability, buoyancy and other relevant essential requirements,
and to have good handling characteristics.

3.1 STABILITY INFORMATION
- Fully laden displacement was used to evaluate the stability and buoyancy of the boat. The value of this displacement
can be found in the "Technical specifications" paragraph at the beginning of this manual.
- Any changes in the distribution of loads onboard (for example by adding a raised structure for fishing, fitting a radar or
in-mast furling, changing the engine etc.) can significantly affect the boat's stability, trim and performance;
- It is important to keep water in the bilges to a minimum;
- Adding weight high up on the boat will affect stability;
- In heavy weather it is important to close all the hatches, lockers and doors to minimise the risk of water pouring in;
- The boat's stability can be reduced when towing a boat or when using a davit or boom to lift a heavy load;
- Breaking waves are a serious threat to stability.
- Reduce speed in wavy conditions.
- Always adjust the speed and heading of
your boat according to the sea conditions.
- All of the watertight hatches must remain
closed when at sea.
- If the wind exceeds 20 knots, it is
recommended that you stow all removable
protection sheets (lazy bag, Bimini, awnings, ...).

- This boat was tested using the stability rating STIX, which is a worldwide safety measurement of stability and which
takes account of the length of the vessel, its displacement, hull dimensions, stability characteristics and flooding
proofness. This test produced the following results:
Shallow draught keel version
Deep draught keel version
Very deep draught keel version
- This boat is likely to capsize or be overrun if it is over-canvassed. In these circumstances, it may then sink. The sail
plan should be adjusted according to wind and sea conditions and it is important to be particularly vigilant in case of gusty
winds or squalls.

3.2 ACCESS TO THE BOAT
Access to the cockpit
NOTE: It is essential that the guardrails remain closed when under way.
- It is essential that both the cockpit and the
engine compartment are kept closed when at
sea.
- When at sea close the guardrail side-
opening or openings.
- Slamming an access hatch may cause injury
: always close the hatch gently and carefully.
- Do not allow children to open or close the
hatches unsupervised.
- It is essential that companionway access is
kept closed when at sea.
- Close the deck hatches and portholes
before each trip.
- Close all access doors and hatches in heavy
weather or when the sea is rough.
- When under way, keep hull valves and fillers
in the closed position to minimise the risk of
flooding.
