This course was designed to ensure Officers are competent in the key operations of their ECDIS. When the display scale on an ECDIS is set to a scale smaller than an object's SCAMIN value, the object will disappear, thus reducing clutter and improving ENC rendering speeds. The extent of the surrounding navigable water is immaterial: such a mark can, for example, indicate either a shoal which is well offshore, or an islet separated by a narrow channel from the coast. ECDIS navigation procedures and practices. Most grounding are a result of human error, poor planning and incompetency of setting proper ECDIS safety settings. isolated danger marks or cautionary areas 3.
