Chart Correction Template contains the Region A & B IALA Maritime Buoyage symbols required for updating & correcting nautical charts. Keeping charts updated with the Chart Correction Template helps ensure the safety of your crew & vessel. Designed for use with a fine line pen, corrections to nautical charts can be made neatly & quickly with this simple-to-use stencil. These corrections then become a permanent part of the chart. Corrections should be made in ink so they will not be accidentally erased when you are using the chart. Please reference US Nautical Chart No. 1 or UK Admiralty Chart 5011 for assistance with symbol identification. An exact replica of the Chart Correction Template formerly prepared & published by the National Geospatial Intelligence Agency (NGA). TIP: Always check the Local Notice to Mariners & the Broadcast Notice to Mariners file to ensure the chart is fully corrected. Keep a log on the chart or a chart correction card of all the corrections that have been made; this will make it easier to verify the chart’s correction status prior to its next use.
