INTRODUCTION 

 

DUFOUR CATAMARANS is pleased to present this manual that will allow you to learn more about 
your boat. This manual has been developed to help you use your boat safely and with pleasure. It 
contains details about the boat, the equipment supplied or installed and its systems, as well as the 
information about their use. Read it carefully and familiarize yourself with the boat before using it. 
This owner's manual is not a course on the safety of navigation or the marine sense. If this boat is 
your first boat or if you have changed it to a type of boat with which you are not familiar, for your 
comfort  and  safety,  be  sure  to  gain  experience  on  its  manoeuvre  and  use  before  taking  the 
Commands. Your dealer, your national sailing Federation or powerboating or your yacht club will be 
happy to inform you about the relevant sailing schools or instructors in the region. 

Make sure that the wind and sea conditions are in line with the design category of your boat, and 
that you and your crew are able to manoeuvre the boat  under these conditions. Even when  your 
boat is adapted to it, the sea and wind conditions corresponding to the design categories A, B and 
C vary from heavy storm for category A to severe conditions for the top of category C, subject to the 
dangers of waves or gusts and anomalies, and are therefore dangerous conditions, in which only an 
experienced crew, in good shape, and trained, maneuvering a well-maintained boat can navigate 
satisfactorily. This owner's manual is not a detailed maintenance or repair guide. In case of difficulty 
use the builder of the boat or his representative. If a service manual is provided, use it. 

Always use the services of an experienced professional for maintenance, installation of accessories 
or  modifications.  Modifications  that  may  affect  the  safety  characteristics  of  the  vessel  shall  be 
assessed, carried out, and documented by competent persons. The builder of the boat cannot be 
held  responsible  for  any  changes  that  he  would  not  have  approved.  In  some  countries  a  driver's 
licence or authorisation is required or specific regulations are in force. Always properly maintain your 
boat  and  consider the  deterioration that  results from  time  or,  if  applicable,  significant  or  improper 
use. Any boat, however solid it may be, can be severely damaged if it is not used properly. This is 
not compatible with safe navigation. Always adjust the speed and direction of the boat to the sea 
conditions. 

If your boat is equipped with a life raft, read the user manual carefully. The crew should have on 
board all the safety equipment (lifejackets, harness, etc....) corresponding to the type of boat, the 
weather conditions, 

distance from the coast, etc…. This material is mandatory in some countries. 

The  crew  should  be  familiar  with  the  use  of  all  safety  equipment  and  with  emergency  safety 
manoeuvres (recovery of a man at sea, towing, etc.); sailing schools and clubs regularly organize 
training  sessions.  It  is  recommended  that  all  persons  carry  appropriate  flotation  aids  (lifejackets, 
personal flotation aid equipment) when they are on deck. It should be noted that in some countries 
it is compulsory to wear flotation aid in accordance with national regulations all the time. 

WARNING 

Before  taking  the  sea,  the  owner/user  of  the  boat  must  read  this  manual  and  know  its 
contents, in particular all warnings regarding safe use and emergency procedures.  It is 
the owner's responsibility to ensure that the boat is equipped with all the safety equipment 
required  by  law  during  navigation.  The  owner/user  must  also  inform  all  other  crew 
members about the proper use of the boat and the equipment and emergency procedures.
