🔍 Key Concepts

• Red Right Returning in the U.S. lateral system (IALA Region B) and how starboard vs. port daymarks are shaped • What changes (color bands only vs. shape) when a buoy/daymark indicates a preferred channel at a junction • The difference between square and triangular dayboards when inbound from sea

💭 Think About

• When you are inbound from sea and the preferred channel is to starboard, which side’s normal lateral marks (port or starboard) does the junction mark most resemble? • For daymarks in the U.S. system, which geometric shape is associated with the starboard side when returning from sea—square or triangular? • Look at each of the four options: which one matches the basic shape used for a starboard lateral daymark, ignoring color details?

✅ Before You Answer

• Be sure you know that in Region B, starboard aids when returning from sea are red and have a distinctive shape compared to port aids • Remember that a preferred channel mark keeps the basic shape of the preferred side and adds a contrasting color band—so the question is really asking for that basic shape • Confirm in the illustration which option is clearly the triangle vs. square vs. other polygon, then match that to the starboard daymark shape you recalled
