BOTH INTERNATIONAL & INLAND What must be...

🔍 Key Concepts

• Rule 17 – Action by Stand-on Vessel (International & Inland) • The difference between a stand-on vessel’s normal duty (maintain course and speed) vs. her optional/compulsory maneuvering when collision risk develops • How risk of collision and the give-way vessel’s behavior affect when the stand-on vessel may act

💭 Think About

• First, think: under Rule 17, when is the stand-on vessel allowed to maneuver, and when is she required to maneuver? List those specific conditions in your own words. • Ask yourself whether Rule 17 applies only when vessels are in sight of one another, and how that might affect the choices given. • Compare each answer choice to the exact wording of Rule 17. Does Rule 17 mention all of those conditions together, or only some of them?

✅ Before You Answer

• Verify under Rule 11/Rule 17 whether the section on Steering and Sailing Rules applies only to vessels in sight of one another. • Confirm that risk of collision must exist before special collision-avoidance actions by the stand-on vessel are considered. • Check Rule 17 to see if the stand-on vessel must first observe that the give-way vessel is not taking appropriate action before she maneuvers "by her maneuver alone".
