BOTH INTERNATIONAL & INLAND You are making headway in fog and hear a fog signal of two prolonged blasts on your starboard quarter. Which action should you take?

🔍 Key Concepts

• Rule 19 – Conduct of vessels in restricted visibility • Meaning of a fog signal of two prolonged blasts • Relative bearing: what it means when a sound is on your starboard quarter

💭 Think About

• Ask yourself: In restricted visibility, what is your primary obligation when you hear another vessel but do NOT see it? • Think about what two prolonged blasts usually indicate about the other vessel’s status and movement. • Consider whether making a course alteration without knowing the other vessel’s exact position and course makes the situation safer or more dangerous.

✅ Before You Answer

• Verify in Rule 19 what actions are recommended when you detect another vessel by hearing a fog signal forward of the beam versus abaft (behind) the beam. • Check what two prolonged blasts generally mean under the sound signal rules (are they an altering-course signal, a making-way signal, or something else in restricted visibility?). • Before choosing, ask: Does this option minimize risk of collision and avoid making bold course changes toward an unknown contact?
