🔍 Key Concepts

• Rule 24 – Towing and Pushing (International) of the Navigation Rules • The definition and color of a towing light versus a masthead or stern light • Special case: power-driven vessel pushing ahead or towing alongside

💭 Think About

• Ask yourself: In the Rules, how is a towing light specifically defined in terms of color and arc of visibility? • For towing alongside, does the Rule say the towing light is optional, relocated, or described the same way as when towing astern? • Think about whether a towing light is ever described as an all-round light, or if that wording applies to other lights (like anchor or special lights).

✅ Before You Answer

• Look up the exact definition of a towing light in Rule 21 (Definitions) and see what it says about color and arc. • Confirm in Rule 24 what lights are required when a power-driven vessel is pushing ahead or towing alongside—is the towing light still mentioned? • Verify whether any rule says that a towing light must be at the bow or must be all-round, or if those descriptions belong to different types of lights.
