What describes a Bald or very bold alteration of course in collision avoidance?

• A. Minor course change to starboard
• B. Rapid, conspicuous course change to avoid risk
• C. Slowing to anchor
• D. Increase speed

Answer: (B)

When there’s a risk of collision, you want an action that is clear, timely, and effective. A bald or very bold alteration of course is exactly that: a rapid, conspicuous change of course to port or starboard intended to avoid the risk and make your intentions obvious to the other vessel. This kind of maneuver reduces ambiguity and gives the other vessel a predictable path to follow or avoid, helping to prevent a near-miss or collision.

The other options aren’t describing that unmistakable, decisive maneuver. A minor course change isn’t bold enough to clearly signal your intent and avoid confusion. Slowing to anchor isn’t a feasible response when you’re underway and in traffic. Increasing speed can worsen the situation by reducing the time and space available to react.
