Question 1963Navigation General

The correct answer is A) 75°00'W. The time meridian used for tide computations in New York Harbor is 75°00'W, which is the standard time meridian for the Eastern Time Zone in the United States. This is the longitude at which local time is determined for the tide predictions in the New York Harbor area. The other answer choices are incorrect because 60°00'W is the time meridian for the Atlantic Time Zone, 82°30'W is not an established time meridian, and 52°30'W is the time meridian for the Greenwich Mean Time (GMT) zone, which is not used for tide computations in the United States.
