European foreword
This document (EN 17361:2023) has been prepared by Technical Committee CEN/TC 15 “Inland
navigation vessels”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by August 2023, and conflicting national standards shall be
withdrawn at the latest by August 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 17361:2020.
The main changes compared to EN 17361:2020 are listed below:
a) 5.1 has been replaced by the Clause “Watertightness”;
b) 5.4 has been deleted.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document is applicable to outboard ladders for inland navigation vessels. Outboard ladders are used
on inland navigation vessels having great side heights to facilitate safe climbing into ship's boats, safe
disembarking or safe crossing over onto vessels in the case of significantly different boarding heights.
This document specifies safety requirements on design, dimensions and strength and test conditions for
outboard ladders.
Outboard ladders are intended for that range where boarding stairs according to EN 1502 are not
sufficient in length. This range starts at a boarding height of approximately at 2,8 m above the light water-
line.
Outboard ladders are not intended for use by passengers.

4 Safety requirements
4.1 Dimensions
General tolerances: ISO 2768 – c (see EN 22768-1).
The dimensions are shown in Figures 1 to 5 and in Table 1.
Edges shall be rounded to min. R 1,5 mm.
Data which have not been specified shall be selected as appropriate.
4.2 Parts
4.2.1 General
Ouboard ladders are not expected to conform to the designs illustrated here; however, the dimensions
and specifications given shall be followed. Maximum permissible masses are shown in Table 1.

4.2.2.1 The stringers extending on both sides above the platform are used as handholds. On that side
which faces the vessel's wall, the handholds shall be designed according to Figure 5.
4.2.2.2 Stringers and handholds should be made from tubular section tube with ∅ 35 mm ± 5 mm. If
alternative profiles are chosen, it shall be ensured, that they are easy to grasp.
4.2.3 Steps
4.2.3.1 General
Steps are the rungs and the platform.
4.2.3.2 Rung
Rungs shall be made of rectangular profile, e.g. hollow profile 40 mm × 30 mm.
4.2.3.3 Platform
The platform shall be made of water displacing sheet.
