1.3 Introduction
This manual has been written and compiled to make it possible
for you to use your sailing yacht, a DEHLER 35, in a safe and
pleasant way.
Apart from many details regarding the yacht itself, the manual
also contains details about the equipment supplied or integrated
fittings and information on its use and maintenance, in addition
to the information given by the manufacturer. Please read the
manual through carefully and get familiar with everything before
you go sailing with your yacht.
We recommend that you make copies of the important parts of
the manual and of some of the manufacturer’s information, such
as instructions about maintenance and warnings, so as to have
them handy on board in case you need to find out the cause of a
technical fault quickly and remedy it.
We hope you will enjoy your new DEHLER 35 and wish you
good luck and safe sailing.
An owner’s manual however can never replace the knowledge of seamanship which is
necessary.
An Owner’s Manual is a technical document which gives you a general description of the
yacht and its technical systems. It helps the skipper/sailor to handle and maintain the yacht
and its systems safely, identify possible technical faults and sometimes even to rectify these
faults himself. Furthermore it is to the advantage of the owner to undertake maintenance and
servicing of the Dehler 35 and thus maintain its value. Maintenance should only be done by
experienced people. Changes which are done after delivery of the boat without any notice and
confirmation by the yard are out of responsibility of the yard.
The shipyard reserves the right to carry out changes in equipment and technique. The systems
represented in this manual should not be considered as a basis for the sales contract. In this
respect you should use the construction specifications and the relevant price list for the
purchase of your yacht.
PLEASE KEEP THIS MANUAL IN A SAFE PLACE AND GIVE IT TO THE
NEW OWNER, IF YOU SELL THE YACHT.

Yacht Manual DEHLER 35

This owner’s manual is not a course on boating safety or seamanship. If this is your first craft,
or if you are changing to a type of craft you are not familiar with, for your own comfort and
safety, please ensure that you obtain handling an operating experience before “assuming
command” of the craft. Your dealer or national sailing federation or yacht club will be advise
you of local sea schools, or competent instructors. Ensure that the anticipated wind and sea
conditions will correspond to the design category of your craft, and that you and your crew
are able to handle the craft in these conditions. Even when your boat is categorized fro them,
the sea and wind conditions corresponding to the design categories A, B and C range from
severe storm conditions for category A, ti strong conditions for the top of the category C,
open to the hazards of a freak wave or gust. These are therefore dangerous conditions, where
only a competent, fit and trained crew using a well maintained craft can satisfactorily operate.
This owner’s manual is not a detailed maintenance or trouble-shooting guide. In the case of
difficulty, refer to the boat builder or his representative. If a maintenance manual is provided,
use it for the craft’s maintenance.
1.4 Stick on notices - List
List of the most important information, indicated by stick on notices.
Observance of the notices is very important for both the boat and its crew. Non-observance
of the notices can lead to total loss of the boat and problems for the crew. As the skipper
responsible for the boat’s safety you should inform new crew members about the notices and
their meaning.

1.5 Design Category
One of the requirements of the EC Directive on Pleasure Craft is that every boat must belong
to a specific design category.
The yacht type DEHLER 35 belongs to Design Category A.
The Directive describes Design Category A as follows:
Design Category A: High Sea
Designed for longer trips, with possible weather conditions of a force 8 wind or above
(Beaufort Scale) and waves 1) as high as 4 m or more, these boats can continue sailing on
their own. Abnormal conditions such as hurricanes are excluded. Such conditions may be
encountered on extended voyages, for example across oceans, or inshore when unsheltered
from the wind and wave for several hundred nautical miles.
1.6 Identification
For a yacht of this size the EC Directive only provides for B module certification. This means
that the manufacturer certifies the conformity of its construction and equipment with the
directive, but that its stability needs to be tested by a recognised testing institute. The ECB
Niederlande one of the testing institutes authorised by the EC Directive, was in charge of
testing; see the Statement of Conformity on page 12.
The hull identification number was stamped in the gel coat on the surface of the starboard side
of the boat. This is a worldwide unique succession of numbers and letters. For example:
DE-DEH 73011K909
This succession of numbers and letters comprises the following data:
DE Germany, Country of Origin
DEH Unique Shipyard Code
(the Register is kept by the German Boat and Shipbuilders’ Association)
73 Designated Type as chosen by the shipyard
11 Serial Construction Number
