Small craft, engine-driven - Field of vision from helm position (ISO 11591:2011)

ISO 11591:2011 specifies requirements for the field of vision from the helm position, forward and astern, in engine-driven small craft of up to 24 m length of hull.
It is not applicable to tiller-steered craft with maximum speed less than 10 knots or sailing craft.

Motorgetriebene kleine Wasserfahrzeuge - Sichtfeld vom Steuerstand (ISO 11591:2011)

Diese Internationale Norm legt Anforderungen an das Sichtfeld vom Steuerstand aus nach vorn und hinten in
motorgetriebenen kleinen Wasserfahrzeugen mit einer Rumpflänge bis 24 m fest.
Diese Internationale Norm gilt nicht für:
⎯ Wasserfahrzeuge, die mit einer Ruderpinne gesteuert werden (3.10) und weniger als 10 kn (10 Knoten)
Geschwindigkeit erreichen;
⎯ Segelboote (3.11).
ANMERKUNG Fahrweise und Geschwindigkeit können bei kleinen motorgetriebenen Fahrzeugen zu Trimmwinkeln
führen, welche die Sicht nach Voraus zeitweise einschränken. Die Internationale Norm kann nicht sicherstellen, dass ein
Fahrzeug beim Auftreten großer Trimmwinkel während des Übergangs von Verdrängungs- zu Gleitfahrt ohne
Sichtfeldverlust vom Steuerstand aus betrieben werden kann.

Petits navires à moteur - Champ de vision depuis le poste de pilotage (ISO 11591:2011)

ISO 11591:2011(E)
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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11591 was prepared by Technical Committee ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 11591:2000), which has been technically revised.
INTERNATIONAL STANDARD ISO 11591:2011(E)
Small craft, engine-driven — Field of vision from helm position
1 Scope
This International Standard specifies requirements for the field of vision from the helm position, forward and
astern, in engine-driven small craft of up to 24 m length of hull.
It is not applicable to:
— tiller-steered craft (3.10) with maximum speed less than 10 knots;
— sailing craft (3.11).
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.
