More sailors are using marine navigation charts online than ever before. But are these charts suitable and legal for navigation in Australian waters?
At Boat Books, we're often asked whether digital charts can replace traditional paper charts. The answer depends on the source of the chart and whether it meets the requirements for safe navigation.
What Counts as a Legal Nautical Chart in Australia?
For chart carriage requirements, mariners should use official nautical charts published by recognised hydrographic authorities and ensure they are current and suitable for the intended voyage.
Official nautical charts published by the Australian Hydrographic Office (AHO) and the UK Hydrographic Office (UKHO) are widely used for safe navigation in Australian waters, provided they are appropriate for the intended voyage and kept up to date.
Official vs Unofficial Navigation Charts
While many apps and websites offer convenient mapping, they may not contain official hydrographic data or the latest updates.
Official charts typically offer:
- Regular hydrographic updates
- Accurate navigational information
- Recognised chart standards
- Reliable data for voyage planning
Unofficial charts can be useful for general reference or trip planning, but they shouldn't be relied upon as a source for safe navigation.
Are Digital Charts Legal for Navigation in Australia?
Yes, digital charts can be used for navigation in Australian waters when they are official electronic navigational charts (or other approved official chart products), are suitable for the intended voyage and meet the applicable carriage requirements.
Whether you're navigating commercially or recreationally, it’s important to choose your charts carefully. Consider factors such as scale, location, and publication date.
Understanding AMSA Electronic Chart Requirements
The Australian Maritime Safety Authority (AMSA) has specific requirements for electronic navigation on certain commercial vessels.
For safe navigation, always use current charts from an official source and ensure they're suitable for your intended voyage.
Commercial operators should ensure their electronic navigation systems comply with applicable AMSA and carriage requirements for their vessel.
Choosing the Right Marine Navigation Charts for Safe Sailing
When selecting a chart, don't base your decision on convenience alone. Focus on current charts that are appropriate for your cruising area and produced by an official hydrographic authority.
