🔍 Key Concepts

• INLAND Rule 34(a) – maneuvering and warning signals for vessels in sight of one another within half a mile • Meaning of one short blast Inland (intention of course arrangement, not just ‘I am altering to starboard’ as in International) • Duties of stand-on vessel vs give-way vessel in a crossing situation (Rules 15, 16, 17)

💭 Think About

• From the diagram, which vessel is on the other’s starboard side, and therefore which is the stand-on vessel in this crossing? • Under Inland Rule 34(a), when one vessel makes a one‑short‑blast passing signal and you agree, how do you respond: by changing course/speed, by repeating the signal, or by staying silent? • In a normal crossing where everything is clear, is the stand‑on vessel expected to change course/speed immediately when agreeing to a proposed passing arrangement?

✅ Before You Answer

• Verify the Inland meaning of one short blast and how it differs from the International meaning • Check that the vessels are within half a mile and in sight, which makes Rule 34(a) maneuvering signals applicable • Confirm what the stand-on vessel should normally do with her course and speed when a safe passing arrangement has been made and agreed to
