USCG Exam Practice · Compass variation and deviation; T-V-M-D-C

You are the master of a towing vessel and wish to fix your vessel's position. Under 33 CFR §164.78, which of the following methods is specifically prohibited as a sole means of fixing position?

  1. AUsing radar ranges to charted landmarks
  2. BUsing buoys alone✓ correct
  3. CUsing hydrographic contours
  4. DUsing geographic reference points

Why B is correct

33 CFR §164.78(a)(3) explicitly states that the person directing the vessel shall not fix position using buoys alone, because buoys may not maintain exact charted positions due to currents, seas, ice, or collisions. Radar ranges, hydrographic contours, and geographic reference points are all listed as acceptable means.
