BS EN ISO 11591:2011

• - 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.
