🔍 Key Concepts

• Inland Navigation Rules – sound signals for passing and overtaking • Difference between meeting/crossing signals and overtaking signals • Meaning of one short blast vs. two short blasts on inland waters

💭 Think About

• First, decide: are you in a meeting, crossing, or overtaking situation? How does that change the whistle signal used? • Think about what one short blast and two short blasts each communicate on inland waters regarding your intended passing side. • Ask yourself: when you intend to pass on the other vessel’s port (left) side, what standard sound signal announces that intention under the Inland Rules?

✅ Before You Answer

• Confirm that the question is limited to INLAND ONLY (do not use International Rules here). • Verify which whistle signal corresponds to: “I intend to leave you on my port side” or “I intend to overtake you on your port side.” • Make sure the choice you pick is a short blast signal, not a maneuvering signal meant for restricted visibility (prolonged blasts).
