🔍 Key Concepts

• ECDIS (Electronic Chart Display and Information System) primary purpose and core data sources • Difference between chart data layers (what comes from the chart/HO) and system or ship data (what comes from sensors or calculations) • How Notices to Mariners are used in relation to electronic charts

💭 Think About

• Ask yourself: Which option describes information that is more about the ship’s own behavior or performance rather than charted geographic information? • Which items are clearly related to chart production and updates versus onboard calculations or sensor inputs? • Think about what the Hydrographic Office actually provides and what ECDIS must show to be a legal replacement for paper charts.

✅ Before You Answer

• Identify which choices are clearly tied to official ENC (Electronic Navigational Chart) / Hydrographic Office chart data. • Identify which choice most clearly relates to vessel performance characteristics (e.g., maneuvering, turning, squat), not chart features. • Remember that Notices to Mariners are used to update charts—consider whether that means they appear as a separate "data layer category" or are already incorporated into the chart data.
