🔍 Key Concepts

• International Rules (COLREGS), Rule 34 – Maneuvering and Warning Signals • Difference between course alteration signals and passing arrangement signals • How two power-driven vessels in a meeting situation agree on how to pass

💭 Think About

• Ask yourself: Under the International Rules, what does a two-blast signal describe: a change of course, or a side-to-side passing arrangement? • Think: In a head‑on/meeting situation, what are the normal expectations for how vessels pass, and how do they propose an alternative if needed? • Compare the wording: which options describe an intention to alter course, and which describe a desire about how to pass relative to the other vessel?

✅ Before You Answer

• Verify in Rule 34 whether two short blasts is defined as an intention to alter course to port or a desire to pass on a particular side. • Check which phrases in the options match the exact type of signal used in the International Rules (intention vs. desire). • Confirm that this question says INTERNATIONAL ONLY, so do not use Inland whistle-signals for passing agreements.
