What will be the velocity of the tidal current south of Doubling Point, ME, at 1357 EST (ZD +5) on 3 April 1983?

Correct Answer: Option C — 2.0 knots

Calculating current velocity requires referencing the NOS Tidal Current Tables for the specific date and station, applying appropriate harmonic constants, time differences, and drift ratios to determine the vector speed at the exact requested standard time.
