Operational Level 3M/2M 1600T 500T Ocean or Near Coastal

The following pages contain references to various references to points of land, lights, buoys, etc. that are used by the National Maritime Center (NMC) in their chart plots solutions.

Learning where these points can be found on the individually referenced chart will be of aid to you in solving the chart plot more quickly and efficiently.

As you find each point a check off box is provided so you know when you have covered them all.

Good luck on your chart plots.
