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.
