🔍 Key Concepts

• Definition in Rule 3(g) of the Navigation Rules for a vessel restricted in her ability to maneuver (RAM) • Difference between deep-draft constraint and inability to deviate from course due to work or nature of operations • Examples listed in the Rules versus common but incorrect assumptions (like just being large or in a narrow channel)

💭 Think About

• Which options describe a vessel whose work or operations physically prevent her from keeping out of the way of other vessels? • Which situations are explicitly listed in Rule 3(g) as examples of restricted maneuverability? • Is being large, deep-draft, or in a channel by itself enough to make a vessel "restricted in her ability to maneuver" under the Rules?

✅ Before You Answer

• Re-read Rule 3(g) and look for the specific examples (e.g., vessel engaged in laying, servicing, or picking up certain equipment). • Check which choice involves special operations where the vessel cannot freely alter course and speed to avoid others. • Make sure you are not confusing a vessel constrained by her draft (a different definition) with a vessel restricted in her ability to maneuver.
