Overreliance on ECDIS

What should have been a routine re-routing becomes an expensive and career-ending error when a crew relying on ECDIS fails to assess the reliability of the ship’s electronic nautical charts (ENC), which were based on information from the 1960's. Don't let it happen to you!


  • Get to know where the ENC data within ECDIS technology comes from.
  • Understand why you still need to assess the reliability of your ship’s electronic nautical charts (ENC).
  • Understand why the Category Zones of Confidence (CATZOC) codes for ENC data are important to know.
  • Learn why sufficient voyage planning has to include traditional skills like conferring with local pilots, consulting pick reports, and identifying sector lights.
