🔍 Key Concepts

• Inland Navigation Rules – Sound and Light Signals (Subpart D) • The meaning of one, two, and three short blasts in Inland meeting and crossing situations • Difference between distress signals and maneuvering/intent signals

💭 Think About

• Think about what one short blast means on inland waters in a meeting or crossing situation. How does changing from one to two blasts change the intended maneuver? • Ask yourself: are maneuvering intentions (like leaving another vessel to port or starboard) ever signaled by light as well as by sound at night under the Inland Rules? • Consider which type of signal is used for distress: is it a specific short light flash pattern like this, or something else (such as flares, radio, or continuous flashing)?

✅ Before You Answer

• Verify in the Inland Rules that maneuvering signals by whistle (one, two, three blasts) have equivalent light signals at night for vessels in sight of one another. • Confirm whether distress is indicated by random short flashes or by specific, more sustained signals (e.g., continuous or long-duration signals). • Check that the option you choose matches an intention relative to the other vessel’s side (port vs. starboard) rather than a change in communication method or an emergency condition.
