🔍 Key Concepts

• Rule 28 – Vessels Constrained by Their Draft (International Rules) • The difference between all-round (360°) lights and masthead (225°) lights • The color and number of lights used to indicate special conditions (e.g., restricted ability to maneuver, not under command, constrained by draft)

💭 Think About

• Compare what lights are carried by a vessel constrained by her draft versus a vessel restricted in her ability to maneuver—how many lights and what colors for each? • Ask yourself: for a special condition that must be visible from all directions, would it make sense to use all-round lights or masthead (225°) lights? • Think about which light color is commonly used to indicate a vessel that other vessels should keep clear of, and how many such lights are stacked to show this specific condition.

✅ Before You Answer

• Verify in Rule 28 (International) exactly how many lights are required and their color for a vessel constrained by her draft. • Confirm whether the required lights must be all-round (visible 360°) or masthead/steaming lights (225°). • Check that the chosen option reflects that this is an International-only signal and not something used in Inland Rules.
