What does the Safe Water Mark indicate and what does it look like?

• A. It marks safe water in all directions; typically a white buoy with red vertical stripes.
• B. It marks shallow water near rocks; blue and yellow striped buoy.
• C. It marks restricted area; black and white checkered buoy.
• D. It marks preferred anchorage; green conical buoy.

Answer: (A)

The main idea here is that Safe Water Marks tell you there is safe navigable water in all directions around the mark. They’re used to indicate that the area is not hazardous and you can pass on either side without danger, often marking the entrance to a channel or a safe area for vessels. This is best conveyed by a white buoy with red vertical stripes, which is how Safe Water Marks are visually identified. At night or in low visibility, the mark is distinguished by its topmark (a red sphere), helping you recognize it when you can’t rely on color alone. The other descriptions point to different kinds of marks or purposes, not to safe water in all directions, so they don’t fit as well.
