🔍 Key Concepts

• Review Navigation Rules, Rule 24 – Towing and Pushing day shapes • Remember the standard shapes: ball, cone, cylinder, diamond and what each one means • Compare what day shapes indicate anchor and not under command versus those used for towing

💭 Think About

• Look closely at the illustration: is it a ball, two balls, a cylinder, or a diamond shape? What condition does that particular shape represent? • Which of the answer choices are clearly associated with anchor or not under command, and do those conditions match the shape shown? • Among the towing-related options, which one specifically uses a diamond day shape under the Rules?

✅ Before You Answer

• Verify in Rule 24 what day shape is required when the length of tow exceeds 200 meters • Confirm what day shape is used for a vessel at anchor and for a vessel not under command and see if the picture matches either of those • Make sure you distinguish between a tow that is simply hazardous and a tow that is very long—only one of these has a special day shape requirement
