USCG Exam PracticeRule 32 — Sound Signal Definitions
Under the Inland Navigation Rules, two power-driven vessels are in sight of one another and approaching within half a mile. Vessel A sounds one short blast. What is the correct meaning of that signal?
- A. I am altering my course to starboard
- B. I intend to leave you on my starboard side
- ✓ I intend to leave you on my port sideCorrect
- D. I am operating astern propulsion
Why C is correct
Under 33 CFR §83.34(a)(i)(1), one short blast means 'I intend to leave you on my port side.' This is an intent signal, not a course-alteration signal as used under COLREGs. Two short blasts means 'I intend to leave you on my starboard side' per §83.34(a)(i)(2).
