Light List for coastal waters are ___

The Light List for coastal waters is a critical reference used by mariners, detailing the characteristics and locations of navigational aids such as lights and buoys. The correct answer asserts that the Light List is accurate through the date shown on the title page. This means that while the information is reliable up to that specified date, subsequent changes or corrections may occur after that publication date.

This reflects the dynamic nature of navigational aids, which can be updated due to maintenance, changes in signal characteristics, or even repositioning of aids as waterways are altered. Mariners must always check for any updates, corrections, or addenda that may be issued after the publication date to ensure they have the most current information for safe navigation.

In contrast, the other options suggest varying publication schedules or imply that the Light List does not require corrections, which is misleading. The system of corrections is essential to keeping the information accurate and reliable for users, highlighting the importance of staying informed about any amendments or updates following the publication date.
