🔍 Key Concepts

• Meaning of the day shape ball–diamond–ball in the Navigation Rules (see Rule 27 - Vessels Not Under Command or Restricted in Their Ability to Maneuver) • How other vessels must act around a vessel restricted in her ability to maneuver (see Rule 18 - Responsibilities Between Vessels) • Difference between a vessel in distress and a vessel that is restricted in ability to maneuver

💭 Think About

• What type of work or condition would make a vessel unable to easily move out of your way, and which day shape represents that? • If another vessel’s movements are limited by their work, are you normally the stand-on vessel or the give-way vessel around them? • Looking at the four choices, which option best reflects your obligation when you are the one that can more easily maneuver?

✅ Before You Answer

• Identify correctly that ball–diamond–ball is NOT the distress signal shape • Confirm from Rule 27 that this shape indicates a vessel restricted in her ability to maneuver • From Rule 18, verify which vessel must keep clear when encountering a vessel that is restricted in her ability to maneuver
