The Office of Navigation Systems announced today in the Federal Register an update to Navigation and Inspection Circular 01-16: Use of Electronic Charts and Publications In Lieu of Paper Charts and Publications. The policy identifies acceptable equivalencies to paper charts and publications as well as position fixing and plotting requirements under Coast Guard Regulations.

This guidance applies to U.S. vessels subject to U.S. chart, or map and publication carriage requirements, as codified in Titles 33 and 46 CFR, and provides a voluntary alternative means to comply with those requirements.

Along with announcing the equivalency, the updated NVIC provides guidance to marine inspectors and recommendations to mariners regarding:

  • How to identify equivalent electronic charts and display systems
  • The integration of other navigational information
  • The limitations of positioning sources
  • Back-up arrangement recommendations
  • Training recommendations
  • Cyber considerations


As a reminder, mariners are not required to use electronic charts or electronic charting systems. This update offers a voluntary alternative means to comply with U.S. chart and publication carriage requirements.
