🔍 Key Concepts

• Rule 24 – Towing and Pushing (Navigation Rules) and the special case for inconspicuous partially submerged tows • Difference between shapes for vessels constrained by their draft, towing over 200 m, and objects being towed • Where shapes are shown: forward end vs. after (aft) end of the tow or object

💭 Think About

• First, recall which single shape is used to mark the after end of an inconspicuous partially submerged object or tow, and which combination of shapes is used to mark the forward end when the length exceeds 200 meters. • Look at each choice and ask: does this represent a single shape or a combination of two shapes, and which of those is associated with inconspicuous partially submerged tows in Rule 24? • Think about what additional shape (if any) is added when the tow is over 200 meters long, and whether that extra shape goes at the forward or after end.

✅ Before You Answer

• Verify in Rule 24 that the forward end of an inconspicuous partially submerged tow over 200 m shows two shapes in combination, while the after end shows only one shape. • Confirm exactly which geometric shapes (ball, diamond, cone) are prescribed for these tows and how many are required at each end. • Double-check the wording: the question asks specifically for the after end of an inconspicuous partially submerged object being towed over 200 m, not the towing vessel or the forward end.
