USCG Exam Practice · Rule 35 — Sound Signals in Restricted Visibility
A pilot vessel engaged on pilotage duty is at anchor in restricted visibility. In addition to the prescribed anchor bell signal, which optional signal may she sound to identify herself?
- AOne prolonged followed by two short blasts
- BFive short and rapid blasts
- CFour short blasts✓ correct
- DOne short, one prolonged, and one short blast
Why C is correct
33 CFR §83.35(k) permits a pilot vessel engaged on pilotage duty to sound an identity signal of four short blasts in addition to the signals prescribed in §83.35(a), (b), or (g). One short, one prolonged, and one short blast is the optional warning signal available to any vessel at anchor under §83.35(g), not the pilot vessel identity signal.
