• Rule 27 – Vessels Not Under Command or Restricted in Their Ability to Maneuver in the Navigation Rules • Difference between number of red lights and number of black balls (shapes) for vessels not under command • Distinguish between vessel not under command and vessel restricted in her ability to maneuver

💭 Think About

• First, recall exactly how many red all-round lights in a vertical line a vessel not under command must show at night. Is it two or three? • Next, think about the day shapes: how many black balls in a vertical line are required for a vessel not under command? • Compare each answer choice to the requirement in Rule 27. Which options show a combination (lights and shapes) that does NOT match the proper not-under-command signal?

✅ Before You Answer

• Verify in Rule 27 whether a vessel not under command shows two or three red all-round lights at night • Verify whether the correct day shape for a vessel not under command is two black balls or three black balls in a vertical line • Check that the number of lights and shapes match each other according to Rule 27; eliminate any option that gives a combination that does not exist in the rule
