At a MacENC zoom scale of 1:15,000
Gloucester harbor is 42*35.84N - 070*40.12W
Portsmouth to Cape Ann - US4MA04M (approach 1:80,000) covers that.
Plymouth harbor is 41*59.10N - 070*40.26W
Cape Cod Bay - US4MA14M (approach 1:80,000) covers that.
My NOAA ENC download is less than 24 hours old. You can see which cells (charts) are displayed by clicking the "Objects" button in the Chart Manager. Make sure you downloaded ALL of the NOAA ENCs per these instructions..

If you want Harbor detail (i.e. 1:40,000 or greater) then I recommend supplementing the NOAA ENCs with the Maptech raster charts.
