🔍 Key Concepts

• Inland Navigation Rules – Sound and Light Signals (Subpart D) • Meaning of one short blast in a meeting or crossing situation on inland waters • Difference between course change vs intention relative to the other vessel (which side to pass on)

💭 Think About

• Ask yourself: In Inland Rules, when two power-driven vessels are meeting, does one short blast describe the direction of the helm or which side you intend to leave the other vessel on? • Think about typical port‑to‑port vs starboard‑to‑starboard meetings: which whistle signal is associated with a standard port‑to‑port meeting? • Compare Inland to International: which answer choice sounds more like the International meaning, and which sounds like the specific Inland convention for passing?

✅ Before You Answer

• Verify in the Inland Rules that one short blast in a meeting situation states the intended passing arrangement, not just a generic turn. • Check which side (port or starboard) is normally used for the standard meeting situation between two power‑driven vessels. • Make sure the wording in the correct option mentions the relative position of the other vessel (which side you’ll leave her on), not only your own rudder or heading.
