This shore furnishes excellent mackerel fishing during most of the season when these fish are in northern waters. Virtually no gill-netters operate here, the distance to market being great and the chance of rough weather and the lack of safe harbor making it dangerous for small craft. From this stretch of shore (mostly from off Chatham) there were landed at Boston in the year 1923, 66 fares with a total of 1,797,826 pounds valued at $76,875. Tobins. A name given to a piece of ground about 20 miles square lying S. by E. from the Highland Light. It runs from about 40 miles to about 60 miles offshore, the depths gradually increasing as the bottom slopes away evenly from the shore from 75 to 95 fathoms over a bottom of clay, sand, and pebbles. Cod are taken here in the spring, summer, and fall, and haddock in February, March, and April. A few hake are taken here in summer, but, as compared with the grounds off Chatham, this is not to be considered a hake ground. Morris Ledge. This lies eastward of Chatham and is a favorite ground for certain cod fishermen during spring and early summer. Schooners and small craft operate here. Outer Crab Ledge. The center lies about 14 miles ESE from Chatham Lights. It extends about 5 or 6 miles in a N. and S. direction and is about 1 mile wide. Depths run from 19 to 23 fathoms; the bottom is rocky. The fishing is principally for cod in the fall, winter and spring. Vessel fishing here is principally in the spring. Nantucket Shoals. This stretch of bars and deeper waters between, roughly triangular in form with its apex at the north, lies along the western edge of the South Channel, extending S. and SE. from the southern end of Cape Cod and Nantucket Island. From Monomoy Point to Rogers Fishing Ground, on the eastern edge of Phelps Bank, it is SSE. 80 miles. Its width from Southeast Rips to the western edge of New South Shoal is 40 miles. The area includes a number of "fishing spots" and shoals, among which the following are the most important: Pollock Rip Ground, Rose and Crown Shoal, Great Rip, Davis Bank, Fishing Rip, Old and New South Shoal, and Phelps Bank.
