Cod Fishing Off Plymouth: Winter Season Guide for Cape Cod Bay
Plymouth's Cold-Water Tradition
When autumn stripers head south and tuna boats haul out for the season, Plymouth's waterfront shifts focus to a fishery with deep New England roots: Atlantic cod. From December through April, the waters of Cape Cod Bay and the southern portions of Stellwagen Bank hold cod populations that draw party boats and charter vessels from Plymouth Harbor into productive winter grounds.
Plymouth's position on the western shore of Cape Cod Bay provides direct access to cod habitat without the long open-ocean runs required from ports farther south. The fishing grounds lie 10-30 miles from the harbor, making same-day trips practical even during the short winter daylight hours.
Where Plymouth Boats Fish for Cod
Cape Cod Bay
The bay itself holds cod from late fall through early spring, particularly along the rocky bottom areas off the Plymouth shore and in the deeper channels running through the bay. Water depths of 40-80 feet hold fish close to structure — wrecks, rock piles, and hard bottom areas that provide habitat for the crabs and shellfish that cod feed on.
Stellwagen Bank (South End)
The southern end of Stellwagen Bank is accessible from Plymouth in about 90 minutes of steaming. This area holds larger cod than the inshore bay grounds, with fish averaging 8-15 pounds and occasional specimens exceeding 30. The hard-bottom areas along the bank's southwestern edge are particularly productive.
| Month | Primary Area | Water Temp | Avg Cod Size | Other Catches |
|---|---|---|---|---|
| December | Cape Cod Bay inshore | 45-48F | 4-8 lbs | Haddock, pollock |
| January | Bay + Stellwagen south | 38-44F | 6-12 lbs | Pollock, cusk |
| February | Stellwagen south | 36-40F | 8-15 lbs | Pollock, haddock |
| March | Stellwagen + bay | 38-42F | 6-12 lbs | Haddock, pollock |
| April | Cape Cod Bay | 42-48F | 5-10 lbs | Transitioning to stripers |
Tackle and Technique
Winter cod fishing from Plymouth boats follows the classic New England bottom-fishing playbook. Heavy tackle, heavy sinkers, and hearty bait dropped to structure on the bottom.
Standard Cod Setup
- Rod: 6-7 foot heavy-action boat rod
- Reel: Conventional reel with strong line capacity
- Line: 50-65 lb braided line for bottom sensitivity
- Rig: Hi-lo (two-hook) rig with 6/0-8/0 circle hooks
- Sinker: 8-16 oz bank or sash weight depending on current
- Bait: Clam strips, squid, and cut mackerel — fresh is always better
Jigging
Diamond jigs (8-16 oz) produce quality cod, often outperforming bait on days when fish are active. Drop to bottom, lift 3-5 feet, and let the jig fall back on slack line. Cod strike on the drop. Add a strip of squid or clam to the jig hook for scent.
There's a satisfying simplicity to winter cod fishing out of Plymouth. Drop your rig to a wreck in Cape Cod Bay, wait for the rod tip to nod, lift into a heavy fish, and reel it to the surface. No complicated presentations, no finicky bites — just honest bottom fishing in cold water with the reward of some of the best-eating fish in the ocean.
Party Boats and Charters
Plymouth's for-hire fleet runs dedicated cod trips from December through April. Party boats carry 20-40 anglers on full-day trips at $100-$150 per person, with bait included. Private charters offer a more focused experience for $800-$1,400 for a full day.
The Plymouth charter fleet departs from the town wharf and Plymouth Harbor marinas. Most winter trips run 7-8 hours, departing at first light and returning mid-afternoon.
Regulations
Atlantic cod are managed under federal regulations through the New England Fishery Management Council. Recreational anglers must follow current size and bag limits set by NOAA Fisheries. Regulations can change during the season — verify limits before every trip. Massachusetts also requires recreational saltwater fishing registration through the state portal.
Plymouth's winter cod fishery offers a productive reason to keep fishing through the cold months. The accessible grounds, experienced fleet, and quality fish make this a worthwhile pursuit for anglers willing to layer up and head offshore when most others have hung up their rods for the season.
