USCG Exam PracticeLeeway allowance in plotting
Under the Inland Navigation Rules, when two power-driven vessels are in sight of one another and within half a mile, and one vessel sounds one short blast, the other vessel is in agreement with the proposed maneuver. What action shall the agreeing vessel take?
- A. Sound five short and rapid blasts and take precautionary action
- B. Sound one prolonged blast and alter course to starboard
- ✓ Sound the same signal and take the steps necessary to effect a safe passingCorrect
- D. Sound two short blasts to confirm the port-side passing
Why C is correct
33 CFR §83.34(a)(ii) states that upon hearing the one or two blast signal of the other, if in agreement, the vessel shall sound the same whistle signal and take the steps necessary to effect a safe passing. Sounding a different signal or five blasts would indicate doubt, not agreement.
