🔍 Key Concepts

• Differences between chart corrections and planning publications • Which publications are updated frequently versus reissued less often • Role of weekly USCG and NGA publications for safety-related changes

💭 Think About

• Ask which option is specifically designed to broadcast new safety and navigational changes on a frequent, regular schedule • Consider which publications are more like reference books used for voyage planning rather than frequent updates • Think about which item would report things like new dangers, buoy relocations, and changes to lights soon after they occur

✅ Before You Answer

• Identify which choice is known to be issued on a weekly basis • Determine which options are usually bound books updated only when a new edition is printed • Match each option with its main purpose: planning information vs ongoing corrections/alerts
