Stay safe on the water by ensuring your nautical paper charts are accurate. Boat Books tells you how to use Notices to Mariners to stay up to date, and when replacing an older chart is the safer option.
Here’s what you’ll learn:
- What Notices to Mariners are
- How to correct paper charts
- Why corrected charts improve safety
- When to replace old charts
Even the most accurate nautical paper charts need regular updates to remain reliable.
Here at Boat Books, we understand just how important it is to have the latest information at your fingertips. Notices to Mariners help you keep up with changes to waterways, navigational aids, and hazards.
Let’s take a look at how to use these essential marine publications correctly and apply them to your nautical charts in Australia.
What Are Notices to Mariners?
Notices to Mariners are official updates issued to inform mariners of changes that could affect navigation.
These may include:
- New buoys
- Altered shipping channels
- Relocated beacons or newly reported wrecks
- Revised depth information
Rather than replacing your existing Admiralty charts, these notices allow you to keep them current by making manual corrections where required.
How to Correct Nautical Paper Charts
Applying Notices to Mariners is a straightforward process when it’s done regularly. Each notice identifies the affected chart and provides instructions for making corrections.
Typical chart corrections include:
- Updating the position of buoys or beacons
- Marking new navigational hazards or wrecks
- Amending depth soundings or seabed information
- Revising shipping lanes or restricted areas
- Recording the correction date on the chart
Remember that official Australian Hydrographic Office and UK Hydrographic Office charts should be kept current as part of safe navigation.
Why Corrected Charts Improve Safety
Outdated marine charts in Australia can leave you relying on information that no longer reflects actual conditions. Regularly applying Notices to Mariners helps ensure your charts remain accurate, even if they aren’t brand-new.
Correct charts also help you comply with recognised navigational best practice.
When It’s Time to Replace Your Paper Charts Instead of Correcting Them
While Notices to Mariners are useful for keeping charts current, there comes a point when replacement is the safer option.
If your paper chart has become heavily marked, difficult to read, physically damaged, or several editions out of date, corrections may no longer be practical. A new edition will provide clearer, more reliable information and reduce the risk of missing important updates.
