Which data must ECDIS be capable of recording at one-minute intervals?

• A. Current position
• B. Cruising speed
• C. Course made good history
• D. Weather conditions

Answer: (C)

The ability of ECDIS to record course made good history at one-minute intervals is essential for various navigational and operational analyses. Course made good refers to the actual path that a vessel has taken over the ground, which can differ from the intended course due to factors like current, wind, or navigational adjustments. Recording this information at regular intervals allows for a precise understanding of the ship’s trajectory and can aid in navigation safety, route planning, and post-voyage analysis. This capability serves multiple purposes including performance assessment and verification against planned routes, which can be vital for compliance with international shipping regulations and for enhancing overall navigational efficiency. It supports the navigator in identifying trends, determining the effectiveness of the vessel's navigation strategies, and making informed decisions during voyage execution. Although current position, cruising speed, and weather conditions are significant pieces of information, they do not inherently require recording at one-minute intervals within the context of this specific question, which focuses on the history of the course made good.
