When bluefin are off Newburyport

Two local operators list different season windows: Dark Horse runs commercial tuna trips July through December, and Mass Charter Fishing lists its bluefin season as August through November. This page is for skippers running their own boats. It covers when fish are around, where Newburyport boats run, how deep the ledge edge is, how it is fished locally, and who charters it. It won’t promise fish, but it should help you decide where to look. For ramps, marinas and the river entrance, use the Newburyport port page. For biology and behavior, see the Atlantic bluefin tuna species guide.

Where Newburyport boats run

Jeffreys Ledge is the main named ground reached from Newburyport. For how the ledge fits into the wider Gulf of Maine, see the Northeast bluefin guide (see also the Atlantic Northeast fishing guide).
The grounds the local fleet names:
- Jeffreys Ledge: the main ground
- Stellwagen Bank: named by the harbormaster
- Outside Flag: named tuna area
- Pigeon Hill: named tuna area
Jeffreys Ledge
According to the Game and Fish ledge guide, the ledge runs northeast from Cape Ann to Cape Neddick. Newburyport sits inside that span.
Stellwagen Bank
Harbormaster Paul Hogg, quoted by Northshore magazine, names Stellwagen Bank as a ground for Newburyport boats.
Outside Flag and Pigeon Hill
The same harbormaster names Outside Flag and Pigeon Hill as tuna areas that the local fleet talks about.
Grounds and structure

The shallow features are at the river mouth. The fish-holding structure is offshore on the ledge.
River mouth flats
Joppa Flat, on the Newburyport side of the Merrimack River mouth, is 5 ft deep. Salisbury Flat is 7 ft.
Jeffreys Ledge depth
The ledge sits at about 160 ft. Game and Fish puts the working range on the ledge at about 160 to 210 ft, on the reasoning that bluefin cruise the edge and feed on bait the current pushes up.
| Ground | Depth | Note |
|---|---|---|
| Joppa Flat | 5 ft | Merrimack River mouth, Newburyport side |
| Salisbury Flat | 7 ft | Shallow feature at the river mouth |
| Jeffreys Ledge | about 160 ft; edge about 160 to 210 ft | Main named ground, reached from Newburyport |
| Stellwagen Bank | Named by the harbormaster | |
| Outside Flag | Named tuna area | |
| Pigeon Hill | Named tuna area |
To read the 160 to 210 ft edge on the chart, use the Chart Contours layer in Breakpoint. Chart layers are not for navigation.
How it is fished here

Anchoring at the ledge edge is the local method. For drifting, trolling and other approaches, see the tuna fishing guides.
Anchoring the edge
Game and Fish advises anchoring at or just over the edge of the ledge, where bluefin cruise on bait the current pushes up.
