🔍 Key Concepts

• Review Rule 24 – Towing and Pushing in the Navigation Rules for day shapes used by tugs • Recall the standard day shapes for vessels at anchor and vessels not under command • Identify what a single black diamond shape (not ball–diamond–ball, not two balls) indicates in towing situations

💭 Think About

• What day shape does a tug display when the length of tow reaches a certain minimum distance? How many shapes and of what type? • Which day shapes are used for not under command and at anchor, and do they look like the shape in the illustration? • Is hazardous cargo shown by shapes on the tug, on the tow, or by some other means (lights, signals)?

✅ Before You Answer

• Confirm from Rule 24 what a single black diamond means for towing during the day • Verify that not under command is indicated by two black balls in a vertical line, not a diamond • Verify that at anchor is indicated by one black ball, not the shape shown in the illustration
