USCG Exam PracticeRule 18 — Responsibilities Between Vessels
Under the International Rules only, any vessel other than a vessel not under command or a vessel restricted in her ability to maneuver shall avoid impeding the safe passage of a vessel that is ______.
- A. engaged in fishing and displaying the prescribed day shapes
- B. a sailing vessel proceeding under sail alone
- ✓ constrained by her draft and exhibiting the prescribed signalsCorrect
- D. restricted in her ability to maneuver in a narrow channel
Why C is correct
COLREGs Rule 18(d) creates an obligation to avoid impeding a vessel constrained by her draft that is exhibiting the signals prescribed in COLREGs Rule 28. Inland Rule 28 is reserved; the Inland Rules do not recognize a vessel constrained by her draft as a distinct class, making this an International-only provision.
