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

Correct Answer: Option A — reduce speed and stay in the deepest part of the channel

In restricted waterways, reducing speed minimizes hydrodynamic pressure differentials around the hull, while staying in the deepest part of the channel maximizes under-keel clearance and lateral separation from banks, preventing sudden hydrodynamic sheers.
