INTERNATIONAL ONLY If a vessel displays three all-round red lights in a vertical line at night, during the day which shape(s) may she show?

🔍 Key Concepts

• Rule 27 – Vessels Not Under Command or Restricted in Their Ability to Manoeuvre (International Rules) • The link between night lights and corresponding day shapes • Number of red all-round lights compared with number and type of black shapes shown by day

💭 Think About

• First identify: A vessel showing three all-round red lights in a vertical line at night is in what special condition or status under Rule 27? • Once you know that status, what is the standard day shape prescribed for that type of vessel (how many shapes, what color, and what basic geometric form)? • Compare each option: which one actually matches the standard day shape for that vessel status under the International Rules?

✅ Before You Answer

• Verify in Rule 27 which vessel exhibits all-round red lights and how many (two vs three) are normally prescribed • Check carefully how many shapes and of what basic form and color (ball, cone, diamond, cylinder) are required for that same vessel during the day • Make sure the choice you pick has the correct number of shapes and correct geometry for that vessel’s status, not just any special shape used by other restricted-condition vessels
