🔍 Key Concepts

• Left bank / right bank are defined looking downstream (with the current) on a river • In inland river navigation, terms like ascending and descending describe a vessel's direction relative to the current • Think about which vessel direction would place a light on the "left bank" to the port side of the vessel

💭 Think About

• First, picture yourself looking downstream: which side is the left bank? • Now imagine a vessel moving upstream vs. downstream vs. from seaward vs. crossing—for each case, which side of the vessel would that left bank be on? • Which of the listed directions of travel would make the left bank physically lie on the vessel’s port side?

✅ Before You Answer

• Be sure you remember that riverbanks are named looking downstream (with the current), not from the vessel • Check what ascending and descending a river mean in standard river terminology • Confirm which direction of travel would place the downstream-defined left bank on your vessel’s port side
