Q

A safe water daymark has what shape?

🔍 Key Concepts

• Aids to Navigation (ATON) shapes and meanings per the U.S. Aids to Navigation System • Difference between safe water marks and regulatory/information signs (like no‑wake, danger, exclusion) • How daymarks are shown on charts and in the Coast Pilot / Light List

💭 Think About

• First, recall what a safe water mark indicates and where you might see it (channel centerline, landfall, fairway). What is its basic symbol shape? • Think about other common ATON sign shapes you’ve seen on the water (danger, information, controlled area). Which of the listed shapes are usually used for regulatory or warning signs rather than safe water? • If you’ve seen a chart symbol for a safe water mark, what simple geometric shape is used there, and how would that translate to a dayboard/daymark shape?

✅ Before You Answer

• Be sure you are thinking of a safe water mark (red and white vertical stripes) and not a regulatory sign (like hazard or exclusion zones). • Match each option with the sign type you know: which shapes are used for danger, information, and controlled area markers? Eliminate those. • Confirm which of the options is commonly used to show unobstructed water all around or the center of a channel in both buoy and daymark form.
