Which is a common occurrence when a vessel is running into shallow water?

🔍 Key Concepts

• Squat effect and how it changes a vessel’s draft and under-keel clearance in shallow water • How shallow water affects rudder effectiveness and turning ability • Changes to wake and wave pattern when moving from deep to shallow water

💭 Think About

• Think about what happens to the water flow under and around the hull when you move at speed in very shallow water. • Consider whether the ship tends to sit higher or lower in the water when experiencing squat. • Ask yourself: does shallow water usually make steering easier or harder, and does it usually make the wake bigger or smaller?

✅ Before You Answer

• Verify what squat means: is it an increase or decrease in draft? • Check whether shallow water generally makes the ship more or less responsive to the rudder. • Consider if the wake height and wave pattern typically increase or decrease in shallow water.

Question 1 of 27070

Which is a common occurrence when a vessel is running into shallow water?

The vessel is more responsive to the rudder

"Squat" will cause a decrease in bottom clearance and an increase in draft

The wake is less pronounced

All of the above
