🔍 Key Concepts

• IALA-B lateral system for marks (used in North and South America, Japan, Korea, Philippines) • Meaning of red vs. green lateral marks when entering from seaward • Relationship between port/starboard side of the vessel and the color/shape of buoys in IALA-B

💭 Think About

• When you are "entering from seaward," which direction are you considered to be going: upstream, inshore, or offshore? • In the IALA-B system, which color do you keep on your starboard side when coming from seaward, and which color ends up on your port side? • Think about the common phrase mariners use to remember lateral buoy colors when coming in from sea in IALA-B areas.

✅ Before You Answer

• Confirm you are thinking of IALA-B, not IALA-A • Make sure you are picturing the vessel entering from seaward (coming in), not going out • Verify which color buoys are kept to starboard vs. port in IALA-B when returning from sea, then match that to the choices
