Best Deep Sea Fishing Fishing Spots in Nantucket
From legendary bays to productive reefs, here are the top deep sea fishing fishing spots your captain will target in the Nantucket area.
Nantucket Offshore Tuna Grounds
The deep water south of Nantucket over the continental shelf is a premier bluefin tuna fishery where giant and school-sized tuna chase menhaden, herring, and squid from June through November. The area's proximity to the shelf edge and warm Gulf Stream eddies creates ideal conditions for tuna to concentrate in fishable numbers. Charter boats out of Nantucket run 20 to 50 miles south to reach the tuna grounds for some of the best bluefin fishing in the world.
Rosie's Ledge
Rosie's Ledge is an underwater ridge southeast of Nantucket where the hard bottom rises from surrounding depths to attract cod, pollock, black sea bass, and bluefin tuna. The ledge's structure concentrates baitfish over the hard bottom, drawing tuna and sharks that patrol the edges during warmer months. Bottom-fishing over the ledge produces consistent catches of cod and sea bass while trolling the perimeter targets passing tuna.
The Dump (South of Great Point)
The Dump is a well-known offshore fishing area south of Great Point where the seafloor drops off from the Nantucket Shoals into deeper water, creating a natural bait-concentrating feature. Bluefin tuna, blue sharks, and mako sharks cruise this transition zone following schools of baitfish pushed by currents off the shoals. It is a productive area for both chunking and trolling during summer and early fall.
Davis Bank South
Davis Bank South lies roughly 40 miles south of Nantucket where an elevated section of the continental shelf concentrates marine life in the surrounding deep water. Bluefin tuna, yellowfin tuna, and bigeye tuna are targeted along the bank's edges during warm-water months when Gulf Stream influence pushes bait concentrations over the structure. Long-range offshore charters from Nantucket consider Davis Bank a primary destination for big-game fishing.
