Boat charts are current when corrected in how many months?

• A. 1 month
• B. 3 months
• C. 6 months
• D. 12 months

Answer: (C)

Keeping nautical charts current is essential for safe navigation. Corrections to charts come from Notices to Mariners and Local Notices to Mariners, and there is a standard practice that a chart is considered current if it has been corrected within the last six months. This six-month window ensures depth, hazards, and aids to navigation reflect recent changes, reducing the risk of navigating with outdated information. To stay current, you apply the latest corrections so the chart you’re using stays within that six-month period. Therefore, six months is the correct timeframe.
