USCG Exam PracticeEstimated position from current set & drift
Under 33 CFR §164.11, which of the following items must the person directing the movement of the vessel know BEFORE transiting an area?
- ✓ Predicted set and drift, current velocity and direction, and tidal stateCorrect
- B. Predicted set and drift and tidal state only; current velocity is optional
- C. Current velocity and direction only; tidal state applies only to vessels over 100 GT
- D. Tidal state and gyrocompass error only
Why A is correct
33 CFR §164.11(l), (m), and (n) each independently require that current velocity and direction, predicted set and drift, and tidal state all be known by the person directing the vessel's movement. None of these requirements is optional or tonnage-dependent.
