DANSK DSF/FPREN ISO 11591 PDF

This International Standard specifies requirements for the field of vision from the helm position, forward and astern, small craft of up to 24 m length of hull. It considers different risk assessments for both engine driven and sailing craft due to their different ranges of speed and their related collision hazards. It is not applicable to: -- engine driven tiller-steered craft with maximum speed less than 10 knots; -- rowing boats. 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.
