Q

BOTH INTERNATIONAL & INLAND What shape would a vessel at anchor show during daylight?

🔍 Key Concepts

• Day shapes required by the Navigation Rules (COLREGS) for different vessel conditions (underway, aground, at anchor, not under command, etc.) • Where the rules describe ‘vessels at anchor’ and what they must show by day and by night • The difference between shapes for at anchor vs aground

💭 Think About

• First recall which single day shape is used most commonly, and for what basic vessel status it is associated • Ask yourself: how many shapes are added when a vessel’s condition becomes more restricted, like aground or not under command? • Think about whether ‘no signal’ is ever acceptable for a vessel that is not making way but is still in a position that other vessels must safely navigate around

✅ Before You Answer

• Verify in the Navigation Rules what Rule 30 – Anchored Vessels and Vessels Aground requires for day shapes • Confirm how many black balls are required when a vessel is aground versus just at anchor • Check whether any vessel at anchor is completely exempt from showing a day shape in clear visibility
