🔍 Key Concepts

• Navigation Rules – Rule 24 (Towing and Pushing) day shapes • Which single shape (not a combination) marks a tow exceeding 200 meters in length • How the shapes for tow length, restricted in ability to maneuver, and vessel at anchor differ

💭 Think About

• First, recall from your Rules of the Road summary: what is the required day shape for a tug when the length of tow is over 200 meters? Is it one shape or a stack of shapes? • Look at each option and match it to what you know: which one is used for restricted in ability to maneuver, which for vessel at anchor, and which for a tow over 200 m? • Ask yourself: for a tow less than 200 meters, is there any day shape required? If not, which specific shape is added only when the tow becomes long (over 200 m)?

✅ Before You Answer

• Verify in Rule 24 that a single black diamond is associated with a tow exceeding 200 meters. • Confirm that the ball–diamond–ball combination is for restricted in ability to maneuver, not for tow length. • Make sure you do not confuse the black ball (used for vessels at anchor or making no way) or the two cones apex together (used for vessels not under command or constrained in certain ways) with the long-tow day shape.
