Canadian Boating Practice Exam

What additional information does a nautical chart provide that aids in planning a route?

1. The best fishing spots

2. The location of shipwrecks only

3. Currents, rapids, and other obstacles

4. The history of the waterway

The correct answer is: Currents, rapids, and other obstacles

A nautical chart provides information about currents, rapids, and other obstacles which is crucial for planning a safe and efficient route. This information is not available on a regular map or chart. Option A about fishing spots might be tempting, but this is not the primary purpose of a nautical chart. Option B about shipwrecks is also incorrect as shipwreck locations are not the only information shown on a chart. Lastly, option D about the history of the waterway is not relevant to planning a route and can be obtained through other means. Therefore, the most important and useful information that a nautical chart provides is information about currents, rapids, and other obstacles.
