USCG Exam PracticeRule 35 — Sound Signals in Restricted Visibility
A pilot vessel engaged on pilotage duty is at anchor in restricted visibility. Which combination of signals is she authorized to sound under Inland Rule 35?
- A. The anchor bell signal only; pilot vessels have no additional authorized signals while at anchor.
- ✓ The anchor bell signal, and she may in addition sound an identity signal of four short blasts.Correct
- C. One prolonged blast followed by two short blasts, plus four short blasts as an identity signal.
- D. Four short blasts only, in lieu of the anchor bell signal.
Why B is correct
33 CFR §83.35(k) authorizes a pilot vessel engaged on pilotage duty to sound an identity signal of four short blasts in addition to the signals prescribed in paragraphs (a), (b), or (g). While at anchor, the applicable base signal is the bell signal under paragraph (g); the four-short-blast identity signal is supplemental, not a replacement.
