Motorgetriebene kleine Wasserfahrzeuge - Sichtfeld vom Steuerstand (ISO 11591:2000)
Diese Internationale Norm legt Forderungen an das Sichtfeld vom Steuerstand aus nach vorn und hinten in motorgetriebenen kleinen Wasserfahrzeugen mit einer Rumpflänge bis 24 m fest.
Petits navires à moteur - Champ de visibilité au niveau du poste de pilotage (ISO 11591:2000)
La présente Norme internationale fixe les prescriptions relatives au champ de visibilité vers l'avant et vers l'arrière à partir du poste de pilotage des navires de plaisance à moteur dont la coque ne dépasse pas 24 m de longueur. Elle n'est pas applicable aux voiliers, ni aux navires à barre franche dont la vitesse maximale est inférieure à 10 km (10 noeuds).
NOTE Selon la façon dont les navires de plaisance à moteur sont pilotés et selon leur vitesse, ils peuvent être soumis à des angles d'assiette tels que la visibilité vers l'avant est temporairement occultée. La présente Norme internationale ne peut pas garantir qu'un navire peut être manceuvré sans risque de perte de visibilité temporaire au niveau du poste de pilotage, lorsque le navire prend des angles d'assiette importants en passant du mode déplacement au mode planant.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11591 was prepared by Technical Committee ISO/TC 188, Small craft.
INTERNATIONAL STANDARD ISO 11591:2000(E)
Smallcraft,engine-driven — Fieldofvisionfromhelm position
1 Scope
This International Standard specifies requirements for the field of vision from the helm position, forward and astern,
in small engine-driven craft of hull length up to 24 m.
The following craft are exempt from the application of this International Standard:
� sailboats;
� tiller-steered craft (2.9) with maximum speed less than 10 kn (10 knots).
NOTE Small engine-driven craft can be operated in a manner and at certain speeds causing trim angles such that vision
forward is temporarily obscured. This International Standard cannot assure that a craft can be operated without some temporary
loss of vision from the helm position while operating at high trim angles during the transition from displacement to planing mode.
2 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1
high eye position
�helmsman in standing position� position 1 730 mm above the surface on which the helmsman stands, 400 mm
from the centre of the steering-wheel rim (see Figure 1)
2.2
high eye position
�helmsman in seated position� position 840 mm above the intersection of the compressed seat and the seat back,
400 mm from the centre of the steering-wheel rim (see Figure 2)
2.3
low eye position
�helmsman in standing position� position 1 480 mm above the surface on which the helmsman stands, 400 mm
from the centre of the steering-wheel rim (see Figure 1)
2.4
low eye position
�helmsman in seated position� position 690 mm above the intersection of the compressed seat and the seat-back,
400 mm from the centre of the steering-weel rim (see Figure 2)
2.5
compressed seat bottom
surface of the centre of the helm seat at the intersection of the seat-back and seat-bottom when compressed by a
25 mm diameter spherical object under a vertical load of 100 N (see Figure 2)

3 General requirements
3.1 The helmsman's position shall permit the operator to have a field of vision, including sight of the water
surface, conforming with the requirements of this International Standard when in the fully loaded, ready for use,
condition during cruising, manoeuvring, docking or other extended operational modes.
3.2 All glazing through which vision from the helm station is maintained shall conform with the requirements of
this International Standard and shall have at least 70 % light transmission.
3.3 For craft having more than one helm station, at least one helm station shall meet the vision requirements of
this International Standard. Other helm stations that do not meet the requirements of this International Standard
shall display a sign at these helm stations, in clear view of the operator, with the ISO symbol for caution, ,and at
least the following information in a language acceptable in the country of operation:
CAUTION — Vision from this helm station is limited. Maintain a lookout a
