USCG Exam PracticeLeeway allowance in plotting
Under the Inland Navigation Rules, vessel A sounds one short blast indicating she intends to leave vessel B on her port side. Vessel B doubts the safety of the proposed maneuver. What is the correct action for vessel B?
- A. Sound two short blasts to propose an alternative passing arrangement
- B. Sound one prolonged blast and reduce speed
- ✓ Sound at least five short and rapid blasts and each vessel shall take appropriate precautionary action until a safe passing agreement is madeCorrect
- D. Sound three short blasts to indicate astern propulsion is being applied
Why C is correct
33 CFR §83.34(a)(ii) states that if a vessel doubts the safety of the proposed maneuver, she shall sound the signal specified in paragraph (d) — at least five short and rapid blasts — and each vessel shall take appropriate precautionary action until a safe passing agreement is made. Sounding two blasts would constitute a counter-proposal, not an expression of doubt.
