During daylight, how does a dredge indicate the side on which it is safe to pass?

• A. Two diamonds in a vertical line
• B. A circle
• C. A triangle
• D. A square

Answer: (A)

Two diamonds arranged vertically are the day shape used to mark a dredging operation. Seeing that sign tells other vessels that dredging work is taking place and a wide, careful pass is required. It doesn’t prescribe a fixed pass side; instead you should choose the safest clearance given the activity and traffic, proceeding with extra caution. The other shapes listed are associated with different types of marks and do not indicate dredging.
