I) INTRODUCTION
Dear Madam, Dear Sir,
You have just taken delivery of your new BENETEAU boat and we would like to congratulate you first
of all for the confidence you showed to us in choosing a product of our mark.
A BENETEAU boat is built to last : each boat is subject to particular care in the slightest details, as
early as when she is designed, when she leaves the factory and she is launched ; this way, she will come up to
your expectations for many years.
This manual was meant to help you to enjoy your boat safely. You will find in it the details of your
boat , her fittings and information about the use and maintenance. Read it carefully and get to know her before
you put out to sea.
If this is your first boat, or if you change to a new type of boat (to which you are not used) get some
training to control and sail her , to ensure your safety and comfort. Then you will be able to assume the command
of the boat. Your dealer, your national sailing association or your Yacht club will be very happy to recommend
you local sailing schools or professional instructors.
Have fine and safe sailing time.
(1) Throughout their lives, our boats are regularly improved and benefit from our experience and our
customers’ experience ; therefore the specifications given in this owner’s manual are not contractual and may be
modified without prior notice and up dating obligation.
In the same way, this manual has a general purpose and it may sometimes list some equipments or refer
to some points which are not relevant to your own boat. In case of doubt, you shall always refer to the inventory
list.
KEEP THIS MANUAL IN A SAFE PLACE AND HAND IT OVER TO THE NEW OWNER IF YOU SELL
THE BOAT.

REF DESCRIPTION
1 Water Tank 170 l

7 Filter – Fresh Water System
8 Water Pump
10 Boiler (capacity : 22 l)
13 Galley Sink
14 Washbasin/Shower

The fresh water system supplies the sink in the galley and the washbasins. This supply is made
depending on the models, either by a manual pump, or by an electric pump ; before this pump there is a filter it is
necessary to clean regularly.
Never run an electric pump when the tank is empty otherwise it might be irreparably damaged.
Never force the filling nozzle deep down the filler pipe in order to prevent any over pressure in the
systems and keep an eye on the vent hole(s) through which the water in excess will be discharged.
When the system has not been used for a long period of time, the tanks and pipes shall be cleansed with
an acetic acid solution (white vinegar)
The water flows out from the sink and wash basins through their own skin fitting seacocks ; Close them when the
water system is not used.

(for the boats fitted with an electric bilge pump).
(See the lay out drawing of the system in the owner’s handbook)
