■ Many factors affect the times and heights of the tides: the coastal configuration, the time of the Moon’s southing (crossing the meridian), and the Moon’s phase. The High Tide column on the Left-Hand Calendar Pages, 112–138, lists the times of high tide at Commonwealth Pier in Boston Harbor. The heights of some of these tides, reckoned from Mean Lower Low Water, are given on the Right-Hand Calendar Pages, 113–139. Use the table below to calculate the approximate times and heights of high tide at the places shown. Apply the time difference to the times of high tide at Boston and the height difference to the heights at Boston.
EXAMPLE:
The conversion of the times and heights of the tides at Boston to those at Cape Fear, North Carolina, is given below:
High tide at Boston 11: 45 A.M.
Correction for Cape Fear – 3 55 hrs.
High tide at Cape Fear 7: 50 A.M.
Tide height at Boston 11. 6 ft.
Correction for Cape Fear – 5.0 ft.
Tide height at Cape Fear 6. 6 ft.
