🔍 Key Concepts

• How different types of crossings and obstructions are shown on inland river charts • The typical chart symbol for an overhead cable or power line versus something on or below the water surface • How a ferry crossing is normally marked across a river on navigation charts

💭 Think About

• Look at how the line is drawn: does it suggest something above the water, below the water, or a service that moves back and forth? • Think about which of these four options would logically be represented by a line that crosses completely from one bank to the other at a right angle. • Recall from chart legend/symbols: which feature is often shown as a dashed line running straight across the channel with landing points near each bank?

✅ Before You Answer

• Verify in a chart legend how a ferry crossing is symbolized versus a submarine (underwater) pipeline. • Check whether overhead power lines usually have extra markings, such as clearance figures or tower symbols, rather than just a simple dashed line. • Confirm that pipelines (gas or submarine) are normally labeled or follow a route along or under the riverbed, rather than simply a short dashed span straight across the river.
