Under the IALA Buoyage Systems, safe water marks may show a __________.

🔍 Key Concepts

• IALA Buoyage System and the purpose of safe water marks • Color and light characteristics associated with safe water marks (vs lateral or cardinal marks) • Meaning of Morse ( A ) and composite group-flashing (2+1) in light descriptions

💭 Think About

• First, recall what a safe water mark indicates and where it is usually placed (e.g., mid-channel, landfall). What are its standard colors and patterns? • Compare which of the listed light characteristics you would expect on a mark that indicates there is navigable water all around, not just on one side. • Look at each choice: which colors and flash groups are normally used for lateral marks (port/starboard) or cardinal marks, and which would best fit a mark that is ‘safe all around’?.

✅ Before You Answer

• Verify the standard color of lights and body for safe water marks under IALA (don’t mix them up with port/starboard lateral marks). • Check which flash character, including Morse ( A ), is specifically associated in books/tables with safe water marks. • Eliminate any options that use green or red where you know the safe water mark should have a different light color.
