Question 1 of 27070

What will be the direction and velocity of the tidal current at Provincetown Harbor, MA, at 1405 DST (ZD +4) on 5 May 1983?

🔍 Key Concepts

• Tidal Current Tables for Provincetown Harbor, MA • Conversion between Daylight Saving Time (DST) and standard time using ZD +4 • Using rate and direction at slack water vs. maximum flood/ebb and interpolating between them

💭 Think About

• What is the correct standard time corresponding to 1405 DST when the time zone description is ZD +4, and which current table hour does that put you near? • Around that time on 5 May 1983, is the current closer to slack, building toward maximum, or decreasing from maximum? • Based on the nearby listed times in the table, how would the direction of the current be changing (toward 135° T or 315° T) and what kind of magnitude (near 0, small, or moderate) should you expect?

✅ Before You Answer

• Verify the correct time conversion: adjust 1405 DST to the time used in the Tidal Current Tables for ZD +4. • Check the Provincetown Harbor subordinate station listing and note which reference station and time differences apply for 5 May 1983. • Confirm whether the time falls closest to a slack water entry or a maximum current entry, and estimate the rate (knots) and set (degrees True) accordingly before choosing.
