Q

When steering a tow downstream around the shape of a sand bar, and staying on the proper side of the buoys, an operator should be cautious of __________.

🔍 Key Concepts

• River current behavior when water flows around a sand bar or point • How cross‑currents (set) act on a long tow versus the tug itself • Relationship between channel buoys, the bar, and the strongest current

💭 Think About

• Sketch a top‑down view of the river bend, the sand bar, the buoy line, and your tow going downstream. Which way is the main current bending as it goes around the bar? • Think about a long tow: if the head of the tow is near the bar and the stern is still in the main current, which way will the stern be pulled, and how does that swing the head of the tow? • Which situation would most likely push part of the tow toward shallow water or the bar itself, even though the tug is trying to follow the buoy line?

✅ Before You Answer

• Be clear on where the deep channel is relative to the sand bar and buoys (the buoys mark the safe side). • Consider that the strongest flow will try to swing the stern of the tow and thus pivot the head toward one side—decide which side that is around the bar. • Ask: which option describes a current effect that would most likely put the tow in danger of grounding on or striking the bar, rather than just losing control in open water.
