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.
The following craft are exempt from the application of this International Standard:
. sailboats;
. tiller-steered craft (3.7) 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.paragraph.
