🔍 Key Concepts

• Inland Rule 24 – Towing and Pushing (day shapes for tows and towed objects) • Difference between black ball (commonly used for vessels not under command, at anchor, aground, etc.) and diamond (often related to towing situations) • How the length of the tow affects whether a special day shape must be shown

💭 Think About

• Ask yourself: in the Inland Navigation Rules, which day shape is specifically linked to a long tow (over a certain length)? • Is the day shape in this question required all the time for a towed object, or only when a certain length threshold is exceeded? • Think about whether a partially submerged object is treated more like a vessel at anchor (ball) or like a tow that must indicate its total length (diamond).

✅ Before You Answer

• Look up Inland Rule 24 and find the paragraph dealing with a vessel or object being towed during the day. • Verify which shape (ball or diamond) is specified there for a tow exceeding 200 meters in length. • Confirm whether the rule says that the towed object must show that shape only when the tow exceeds 200 meters, or regardless of length.
