USCG Exam PracticeEstimated position from current set & drift
The master of a small passenger vessel underway wishes to determine an estimated position when no fixed aids to navigation are available. Which of the following is the most appropriate action under federal regulations?
- A. Use buoys alone to establish the vessel's position and log it as a fix
- ✓ Use buoys alone to establish an estimated position, since no fixed aids are availableCorrect
- C. Anchor the vessel until fixed aids to navigation become available
- D. Use only electronic navigational equipment and disregard all visual aids
Why B is correct
33 CFR §164.11 note states that if no other aids are available, buoys alone may be used to establish an estimated position — not a fix. The position must be characterized as estimated, not fixed. This distinction is critical on the exam.
