🔍 Key Concepts

• INLAND Rules – Barge and mooring light exemptions (look in the Annexes and special inland provisions) • Difference between a barge moored to a bank or in a slip and a barge projecting into a channel • Purpose of lighting: marking an obstruction to navigation vs. a vessel safely inside a mooring area

💭 Think About

• Ask yourself: Is a barge inside a slip used mainly for mooring purposes likely to be a danger to vessels navigating in the channel? How does that affect whether lights are required? • Compare what the Rules say about barges moored in or near a fairway versus moored in slips or behind piers. • Which of the options sound like lights meant to warn traffic in the channel of an obstruction, and which option reflects that the barge is tucked away inside a slip?

✅ Before You Answer

• Verify in the Inland Rules/Annexes what is said about barges moored in slips or behind piers. • Check whether there is an explicit exemption for barges in areas "used primarily for mooring purposes." • Confirm that any required lights on moored barges are intended for vessels that could collide with them in the navigable channel, not for those safely inside dedicated mooring slips.
