🔍 Key Concepts

• Bank cushion and bank suction effects when operating near steep banks or revetments • Hydrodynamic interaction between a tow and a nearby vertical surface when there is no current • Difference between how the head of the tow and the towboat’s stern react near a steep bank

💭 Think About

• Think about how water has to move between the tow and the steep revetment when you are pushing ahead—does this tend to push the bow toward or away from the bank? • Consider whether the absence of current makes your speed over the ground change by itself, or if something else must cause that. • Compare which part of the unit (head of tow vs. towboat stern) is more affected by cushion against the bank and which by suction away from it.

✅ Before You Answer

• Verify what bank cushion typically does to a vessel’s bow or the head of a tow when operating close to a steep bank. • Verify whether speed over the ground would automatically increase just because you are running close to a revetment in still water. • Check which is more likely in this situation: the head of the tow sheering away or the stern of the towboat sheering away from the revetment.
