25. What is the predicted velocity of the tidal current 2 miles west of Southwest Ledge for 2330 DST (ZD +4) on 7 September 1983?
The predicted velocity of the tidal current 2 miles west of Southwest Ledge on 7 September 1983 at 2330 DST (ZD +4) is 1.3 knots. This was determined by referencing the 1983 Tidal Current Tables, using the Southwest Ledge reference station and the subordinate station data, adjusting for time differences and velocity ratios, and interpolating for the specific time.
