You will transit the Cape Cod Canal on 7 November 1983. If you arrive at the R R Bridge at 1655 EST (ZD +5), for what period of time during your transit will you have currents of not more than 0.5 knot?

Correct Answer: Option A — 1648 to 1702

Evaluating low-current transit windows in restricted channels requires applying NOS table data for duration of slack, calculating offsets from the exact slack time, and establishing the exact beginning and ending timestamps.
