Q

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

🔍 Key Concepts

• Effect of current and bank suction on a tow in a narrow river • Relationship between speed, rudder effectiveness, and sheer • Advantages of the deepest part of the channel versus shallow water

💭 Think About

• In a narrow river, what happens to your tow when you go faster near the bank versus when you slow down and stay near the center/deep water? • How do shallow areas and proximity to the bank affect the tendency of a vessel or tow to sheer or be grabbed by the bank? • Which combination of speed (higher or lower) and channel position (outer limits vs deepest part) is most likely to give you more control and less bank suction?

✅ Before You Answer

• Compare how high speed vs reduced speed affects sheer in confined waters • Consider where bank suction and cushion are strongest: near the bank or in the deeper center of the channel? • Confirm which channel position gives the most water under the keel and the most predictable handling for a tow
