🔍 Key Concepts

• Navigation lights and shapes for vessels under tow in the Navigation Rules (COLREGS/INLAND) • Difference between day shapes (black geometric figures) and lights (used at night or in restricted visibility) • Rules about obscuring or interfering with required navigation lights

💭 Think About

• Is a jack-up drilling rig under tow treated more like a vessel being towed, or like a working platform underway on its own? • Which option describes a required day shape or sound signal in the Rules, and which options sound more like general safety/common sense measures? • When navigation lights are required, what does the Rules say about other lights that might confuse other vessels?

✅ Before You Answer

• Look in the Navigation Rules section on Towing and Pushing and on lights and shapes for vessels being towed • Confirm whether two black diamonds in a vertical line is actually a recognized day shape combination in the Rules for this situation • Verify the rule that says no other lights may be exhibited that could be mistaken for navigation lights or interfere with them
