On 6 June 1983, at 1719 EST (ZD +5), what will be the predicted height of tide at Chester, PA?

Correct Answer: Option B — 1.1 feet (0.3 meters)

Compute the height of tide at Gargathy Neck by referencing subordinate station corrections against the primary port. Entering the standard tidal curve with the time interval from high/low water at 1800 DST gives a predicted height of 2.9 feet.
