The major consequence of not regularly updating charts in Electronic Navigation (E-NAV) is the increased risk of navigational errors due to outdated information. Navigational charts are crucial for safe passage, as they contain essential details about maritime routes, hazards, and navigational aids.

Outdated information can lead to critical errors in navigation, which may result in grounding, collisions, or other maritime accidents. Navigators rely on accurate and current charts to make informed decisions about course and speed to avoid dangers and ensure a safe voyage. Therefore, the necessity of regularly updating these charts becomes paramount in maintaining safe navigation practices and minimizing the risks associated with navigation.
