Question 1 of 27070

Your vessel is proceeding through a narrow channel. What actions can you take to avoid any sudden sheers of the vessel?

🔍 Key Concepts

• Bank effect and squat in narrow channels • Relationship between vessel speed and controllability in confined waters • Importance of channel depth and position in minimizing sheer

💭 Think About

• How does higher speed affect bank suction, cushion, and squat in a narrow channel? • Where in a channel is bank effect usually strongest, and where is it usually weakest? • Does putting an anchor in the water actually prevent sheer, or can it create new handling risks?

✅ Before You Answer

• Identify how reducing vs. increasing speed changes hydrodynamic forces on the hull and rudder effectiveness • Consider whether being close to the bank/outer limits increases or decreases the risk of sheer • Ask if using an anchor while making way is a standard shiphandling practice in narrow channels or an emergency-only measure

Reduce speed and stay to the outer limits of the channel

Reduce speed and stay in the deepest part of the channel

Increase speed and stay to the outer limits of the channel

Put your offshore anchor well in the water
