Cutter charts are current when corrected in how many days?

• A. 15 days
• B. 45 days
• C. 30 days
• D. 60 days

Answer: (B)

Keeping charts current means applying official corrections so the chart reflects the latest navigational information. For Cutter charts, the standard window is 45 days from the date of the last correction. This time frame balances how often notices to mariners are issued with the practical workload aboard cutters, ensuring you have the latest details on hazards, buoy positions, depth changes, and aids to navigation before you sail. If a chart hasn’t been updated within that 45-day window, you should obtain newer corrections or a replacement chart to avoid relying on outdated information. Shorter intervals like 15 or 30 days aren’t the standard tested here, and 60 days would risk missing important changes. Keeping corrections within 45 days maintains current situational awareness for safer passage planning.
