Question 1 of 27070

When turning a vessel in shallow water, which statement is TRUE?

🔍 Key Concepts

• Shallow-water effects on maneuvering (bank cushion, squat, increased resistance) • Difference between turning diameter and rate of turn • How restricted water depth affects propeller and rudder effectiveness

💭 Think About

• Think about what happens to water flow around the hull and under the keel when depth decreases. Does the ship respond more or less easily to the rudder? • If the vessel "squats" and resistance increases in shallow water, will the ship swing more quickly or more sluggishly? • Imagine doing the same rudder angle and speed in deep water vs shallow water. Which circle would be larger on the chart?

✅ Before You Answer

• Be clear on the definition of turning diameter (distance from original track to the vessel’s track when turning 180° at constant rudder and speed). • Decide whether shallow water makes the vessel’s turning circle tighter or wider at the same speed and rudder angle. • Confirm in your seamanship/maneuvering notes how shallow water generally affects stopping distance and turning ability.
