You are bound for the Chelsea docks in the Hudson River. The Captain wants to arrive at the docks at the first slack water on 28 July 1983. You are keeping daylight saving time. What time should you be at the docks?

Correct Answer: Option A — 0215

Finding the first slack water time requires converting local daylight time to standard time, referencing the daily NOS tidal current tables for the Hudson River, and identifying the exact morning slack period for arrival.
