🔍 Key Concepts

• Inland Rule 34(c) – Overtaking in a narrow channel: what does one vs. two short blasts mean? • Difference between meeting/crossing signals and overtaking signals under the Inland Rules. • Role of the vessel being overtaken – how does it indicate agreement or doubt?

💭 Think About

• First, decide what kind of situation the illustration shows: are the vessels meeting head‑on, crossing, or is one overtaking the other in the same direction? • Once you know it’s an overtaking situation, ask: when vessel "B" (the overtaking vessel) makes a whistle proposal, how is agreement properly indicated by vessel "A"? • Think about whether Inland Rules require you to acknowledge an agreed maneuver by repeating the same signal, using a different confirmation signal, or by remaining silent.

✅ Before You Answer

• Verify in Inland Rule 34(c)(i) what sound signal the overtaking vessel makes and what sound the vessel being overtaken must make if in agreement. • Confirm whether two short blasts in a narrow‑channel overtaking situation indicate passing on the port or starboard side of the vessel being overtaken. • Make sure the option you choose reflects an explicit reply from vessel "A" when it agrees—silence is typically not the way to show agreement in Inland narrow‑channel overtaking.
