In international waters, a signal of intent must be sounded by which vessel?

• A. A vessel entering a traffic lane
• B. A vessel overtaking another in a narrow channel
• C. A vessel approaching a bend
• D. A vessel anchored

Answer: (B)

In this area, vessels use sound signals to communicate maneuvers that could affect other ships, especially in restricted spaces like narrow channels. When one vessel intends to overtake another in a narrow channel, it must make a sound signal to indicate its plan, so the vessels can take appropriate action to avoid a collision. The signal helps the vessel being overtaken know what to expect and adjust speed or course as needed. The other scenarios listed do not involve overtaking someone in a confined space, so there is no required overtaking signal for them. In practice, the overtaking vessel typically emits a standard signal (for example, one prolonged blast followed by two short blasts) to convey this intent, reinforcing why the correct choice is the vessel overtaking in a narrow channel.
