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?
• Use the current and tide tables for the Hudson River for 28 July 1983 • Understand how to interpret slack water at Chelsea docks (flood-to-ebb or ebb-to-flood) • Apply daylight saving time (DST) corrections to the time found in the tables
• First, which reference station and subordinate station would you use to find slack water at Chelsea docks in the Hudson River? • Once you find the predicted time of first slack water on that date, what correction (if any) must you apply for daylight saving time? • Is the time listed in the tables in standard time or corrected for daylight saving time, and how does that affect the clock time you choose?
• Verify you are looking at slack water, not maximum current • Confirm the date and cycle (first slack of the day vs later slack times) • Double‑check that you have correctly applied DST correction (add or subtract one hour as appropriate) before matching one of the answer choices
