Under 33 CFR §164.11, the person directing the movement of a vessel is prohibited from doing which of the following when fixing the vessel's position?
- A. Using electronic navigational equipment as the sole means of fixing position
- B. Using geographic reference points in combination with hydrographic contours

- D. Using a running fix derived from a single advanced LOP
Why C is correct
33 CFR §164.11(e) explicitly states that buoys alone are not to be used to fix the vessel's position. The regulation's note clarifies that buoys may corroborate a fix or establish an estimated position when no other aids are available, but they cannot constitute a fix.
