USCG Exam PracticeEstimated position from current set & drift
The person directing the movement of a vessel underway is required by 33 CFR §164.11 to know which of the following before transiting an area?
- A. Predicted set and drift only; tidal state is required only for vessels over 100 GT
- B. Tidal state only; set and drift are required only for towing vessels under 33 CFR §164.78
- ✓ Both predicted set and drift, and tidal state for the area to be transitedCorrect
- D. Current velocity and direction only; set, drift, and tidal state are advisory
Why C is correct
33 CFR §164.11(l), (m), and (n) each independently require the person directing movement to know current velocity and direction, predicted set and drift, and tidal state for the area to be transited. None of these requirements is limited by vessel size or type.
