BOTH INTERNATIONAL & INLAND During the day, which shape is required for a dredge to exhibit to indicate the side on which it is safe to pass?

🔍 Key Concepts

• Dredging signals (day shapes) in the Navigation Rules (International & Inland) • The difference between shapes showing safe side vs. obstructed side of a dredge • How balls and diamonds are paired vertically to indicate passing information

💭 Think About

• Which shape (ball or diamond) is associated with an obstruction / danger and which is associated with a safe water / passing side? • On a dredge, do you expect the same shape on the safe and obstructed sides, or different shapes? How does that help you distinguish them at a distance? • Look at the answer choices with multiple shapes: which pattern would logically be used for the clear, safe side, not the blocked side?

✅ Before You Answer

• Verify in the Navigation Rules that balls indicate an obstruction or no-passing side for dredging operations • Verify that diamonds indicate the safe side for passing when a dredge restricts the channel • Confirm that the required signal for the safe side is specifically a vertical line of identical shapes, not a mixed combination, during the day
