Good data, totalling the 8 mentioned ports, NYC accounted for almost exactly half! Amazing by any standard, the Southerners would have done well to use it as a model in developing their own shipping (were it not for the whole blockade thing).
Another interesting table can be found on page 139 of the same source, showing the countries of origin of ships entering US harbors from foreign countries (and thus excluding the coastal packet traffic). For 1859, foreign ships account for almost exactly one-third of the total tonnage arriving from foreign countries (1,583,033 out of 4,913,031). This would seem to somewhat undermine the claimed importance of the navigation acts.
