🔍 Key Concepts

• Meaning of regulatory markers on the water (orange and white buoys) • Differences between information, danger, control, and exclusion symbols • How the diamond shape is modified to indicate restrictions versus total prohibition

💭 Think About

• First, recall what each geometric symbol on an orange-and-white buoy is used for: which one gives general information, which one warns of hazards, which one limits activities, and which one completely keeps vessels out? • Think about the difference between an area where certain activities are controlled (like slow speed or no wake) and an area where no vessels are allowed at all—how is that shown visually? • Which symbol most clearly communicates do not enter at all instead of just use caution or obey these rules?

✅ Before You Answer

• Match each shape: square, circle, diamond, and diamond with an additional mark to its specific meaning before answering. • Verify which symbol is used for information versus danger versus controlled area versus exclusion area in standard U.S. Aids to Navigation materials. • Double-check that your chosen symbol means no boats allowed (not just warning or restriction).
