Q

The Light List indicates that a dayboard is a type TR-SY. Which action should you take?

🔍 Key Concepts

• Light List dayboard type codes (TR-SY, TR-TY, etc.) and what each letter stands for • Difference between lateral aids (red/green, port/starboard) and non-lateral aids (special purpose, information, regulatory) • How the Intracoastal Waterway (ICW) aids to navigation are marked and when "leave to port" applies

💭 Think About

• What do the letters T, R, S, Y in TR-SY typically refer to in the context of dayboard types (shape and colors)? • Does a dayboard coded TR-SY indicate a red/green lateral mark, or does it sound more like an informational/regulatory/special mark? • Which of the choices describes behavior appropriate for a lateral aid versus a non-lateral informational or regulatory aid?

✅ Before You Answer

• Verify what TR means (e.g., triangular vs square) and how that relates to lateral vs non-lateral significance. • Confirm what S and Y mean in the Light List dayboard coding (colors: standardized abbreviations). • Decide whether a TR-SY mark would control which side you pass on, or simply convey information without lateral significance.
