USCG Exam PracticeEstimated position from current set & drift
The master of a towing vessel is planning a coastal transit. Under 33 CFR §164.78, which of the following must the person directing and controlling the movement of the towing vessel know regarding current?
- A. The set and drift only; tidal state is not required for towing vessels
- ✓ The speed and direction of the current, and the set, drift, and tidal state for the area to be transitedCorrect
- C. Current velocity only, because the draft of the tow is the primary speed consideration
- D. Tidal state only when transiting waters with a tidal range exceeding 3 feet
Why B is correct
33 CFR §164.78(a)(6) requires the person directing the towing vessel to know the speed and direction of the current AND the set, drift, and tidal state for the area to be transited. All four elements are required; none is optional.
