USCG Exam PracticeCourse to steer to compensate for current
Under 33 CFR §164.11, a navigator may use buoys to accomplish which of the following?
- A. Fix the vessel's position as a primary method when no other aids are available
- ✓ Corroborate a position fixed by other means, or establish an estimated position when no other aids are availableCorrect
- C. Fix the vessel's position provided at least two buoys are used simultaneously
- D. Replace a GPS fix in restricted visibility when the buoys are lit
Why B is correct
33 CFR §164.11(e) and its accompanying note state that buoys cannot be used to fix a position, but may corroborate a position fixed by other means. If no other aids are available, buoys alone may establish an estimated position — not a fix.
