Which symbol corresponds to the information buoy?

• A. White with orange markings
• B. Orange circle
• C. Orange diamond
• D. Orange square

Answer: (D)

In this setup, information marks use an orange square as their symbol. It’s a special mark meant to convey that information about the area is available (like locations of services, rules, or local guidance), not to warn of a hazard or mark a channel. The orange square is distinctive and easy to recognize, which is why it’s the correct symbol for an information buoy.

An orange circle isn’t used to indicate information in this system, and an orange diamond typically signals a hazard or warning area rather than information. A white buoy with orange markings doesn’t match the standard information-mark symbol.
