What will be the set of the rotary current at Nantucket Shoals at 1245 (ZD +5) 14 January 1983?

🔍 Key Concepts

• Use the Tidal Current Tables for the correct year and location (Nantucket Shoals) and find the rotary current diagram for that station. • Understand how time is referenced in the tables (standard time vs. local/zonal time) and how to convert 1245 (ZD +5) to the time used in the diagram. • Follow the rotary current diagram from the reference time of slack or maximum up to the required time to read the set (direction in degrees).

💭 Think About

• Which page or section in the Tidal Current Tables gives you the rotary current diagram for Nantucket Shoals, and what is the reference time indicated (e.g., time of maximum or slack)? • From that reference time, how many hours and minutes have passed by 1245 (ZD +5) on 14 January 1983, and where does that put you on the rotary current diagram? • When you reach that point on the rotary diagram, what is the set (direction) indicated in degrees, and which answer choice most closely matches it?

✅ Before You Answer

• Confirm you are using the correct station (Nantucket Shoals) and not a nearby reference or subordinate station. • Double-check the time conversion so the time you plot on the rotary diagram truly matches 1245 (ZD +5). • Verify you are reading the set (direction of current in degrees true) and not the drift (rate in knots) from the diagram.
