Q

Which statement is TRUE concerning the vessel's slipstream?

🔍 Key Concepts

• Slipstream (propeller race) and how water flows behind a turning propeller • Relationship between slipstream flow and rudder effectiveness, even with helm amidships • Difference between slipstream and the vessel’s wake

💭 Think About

• Think about what the water directly behind the propeller is doing: does it move straight back, or does it have some special pattern? • Ask yourself: does water flowing past the rudder affect steering only when the rudder is angled, or also when it is amidships? • Compare the speed and character of the water in the slipstream right behind the propeller with the more distant, expanded wake.

✅ Before You Answer

• Verify how the propeller blades push and twist the water as they rotate. • Check whether rudder force depends only on the ship’s forward speed, or also on the flow from the propeller. • Confirm whether the wake far astern has the same velocity characteristics as the concentrated flow right behind the propeller (the slipstream).
