🔍 Key Concepts

• shallow water effects on a vessel’s handling • how propeller (screw) race flows past the hull and over the rudder • relationship between propeller wash and rudder effectiveness

💭 Think About

• Visualize the water flow: if the clearance under the keel is very small, where can the propeller’s discharge current go? How will that affect the rudder’s ‘bite’ on the water? • Think about each choice: which one(s) are known symptoms when a ship is in very shallow water at speed? Do they seem related to reduced propeller efficiency, steering control, or both? • Ask yourself whether restricting screw currents would affect only one aspect (steering or power) or several aspects of maneuvering at the same time.

✅ Before You Answer

• For each option, mentally connect it to restricted propeller wash: Does reduced flow past the rudder make this more likely? • Recall that in shallow water ships often experience squat, sluggish steering, and higher power demand. Which options match these handling problems? • Before picking an answer, decide whether the effect of restricted screw currents is single-purpose (just one symptom) or multi-effect (several symptoms together).
