Electronic charts are one of the most powerful tools on board a modern boat. Used well, they make navigation clearer, passage planning easier, and situational awareness far better than it was a generation ago.
Used without understanding, they can also create a false sense of security.
This short course exists to help people use electronic charts properly, with confidence and caution in equal measure.
Why electronic charts need explanation
Most people learn electronic charts by turning them on and seeing where the boat appears on the screen. For a while, that feels reassuring. The problem is not the technology itself. The problem is over-reliance.
Electronic charts are not infallible. They rely on correct setup, correct interpretation, and an understanding of their limits. When those pieces are missing, boats run aground, often in conditions where the crew believed they were completely safe.
This course explains what electronic charts can and cannot do, and how to use them as a safety tool rather than a single point of failure.
What this course actually teaches
The focus is on safe, effective use rather than brand-specific operation.
You learn:
-
How to set up electronic charts correctly for safe navigation
-
How to use them for sensible passage planning
-
What to watch for while underway
-
Where errors and misunderstandings commonly occur
-
How to check and double-check what the screen is telling you
The aim is not to turn people into technicians. It is to help them think critically about what they are seeing.
A problem seen too often
One of the reasons this course was created is simple. Too many boats are running aground.
In many cases, the crew did everything “right” according to the screen. The error lay in assumptions. Scale, settings, chart data, and interpretation all matter. Without understanding those factors, electronic charts can quietly lead you into trouble.
This course addresses those blind spots directly, using real examples and common mistakes seen on the water.
What is deliberately not included
This course does not teach every brand of electronic charting system.
All major systems share the same underlying principles, and the technical operation of buttons and menus is best learned from the manufacturer’s manual or online guides. Including brand-specific detail would add complexity without improving safety.
Instead, the course focuses on correct setup, interpretation, and judgement, which apply across all systems.
Who this course is for
This course is suitable for anyone on board who looks at an electronic chart.
It works for:
-
Beginners who want to start with good habits
-
Boaters who have used e-charts for years without formal instruction
-
People upgrading equipment and wanting to use it properly
-
Anyone who wants to understand the limitations of the screen they rely on
Experience does not automatically equal understanding. This course bridges that gap.
Real experience, practical lessons
The examples used come from real situations, not theory.
Common mistakes are explained clearly, along with what to watch for and how to avoid them. The emphasis is always practical. How does this help you make better decisions on the water, in real conditions?
That perspective comes from using these systems extensively, alongside traditional navigation methods, over many years.
How this course fits with basic navigation skills
Electronic charts and paper charts belong together.
You cannot fully understand what an electronic chart is showing unless you understand the fundamentals underneath it. That is why this course works best alongside basic navigation skills. Learning those fundamentals takes very little time, but it changes how everything else makes sense.
Together, the two courses put people well ahead of the curve, without overwhelming them.
A safer way to use modern tools
Electronic charts are here to stay, and they are incredibly useful. This course does not discourage their use. It makes their use safer.
By understanding their capabilities and their limits, you gain confidence rather than dependence. You become someone who uses the technology, not someone who trusts it blindly.
Where this sits in your learning path
This course stands alone as a practical safety guide. It also complements basic navigation skills and sets a strong foundation for deeper learning later.
For many people, these two short courses together provide exactly what they need to feel safer and more capable on the water.
