USCG Exam PracticeRule 35 — Sound Signals in Restricted Visibility
A vessel restricted in her ability to maneuver is at anchor in restricted visibility. Which fog signal applies to her?
- A. The bell signal prescribed for vessels at anchor only, because she is not underway
- ✓ One prolonged followed by two short blasts, because she is a vessel restricted in ability to maneuverCorrect
- C. Two prolonged blasts, because she is stopped and making no way
- D. One prolonged blast, because she is not making way
Why B is correct
33 CFR §83.35(c) specifies that a vessel restricted in her ability to maneuver, whether underway or at anchor, shall sound one prolonged followed by two short blasts at intervals of not more than 2 minutes. The phrase 'whether underway or at anchor' is explicit, so the standard anchor bell signal of §83.35(g) does not substitute for this vessel type.
