🔍 Key Concepts

• Use the Tidal Current Tables 1983 for the correct region (New York Harbor / approaches). • Understand what slack water means in current tables (very little or no current around the time of reversal). • How to find the time interval when the current speed is less than 0.1 knot before and after the listed slack time.

💭 Think About

• Which specific current station in the tables corresponds to the area east of the Statue of Liberty? Is it a primary or a subordinate station? • Once you find the first PM slack water on 3 March, what are the speeds and times listed just before and just after slack? • How do you convert the time difference between when the current first drops below 0.1 knot and when it rises back above 0.1 knot into minutes?

✅ Before You Answer

• Verify you are looking at 3 March 1983, not another year or month. • Confirm you selected the first PM slack (not the AM slack or a second PM slack if two occur). • Check carefully the times when speed crosses 0.1 knot on each side of slack, and use those two times to determine the duration.
