Blue marlin fishing out of Cape May means a 60 to 70 mile run to the canyon and continental shelf grounds, trolling artificial lures, with July and August built around tournaments. That distance, per the 16-hour canyons trip listing, sets fuel, range and time on the water, and the rest of this page follows from it.
For inlet details, marinas and ramps, see the Cape May port page. Below: when the tournament fleet fishes, which grounds you pass and reach, how the fish are worked locally, and who fishes for them from this port.

The run and the grounds
Plan fuel, range and daylight around 60 to 70 miles before anything else. Check wind, wave height and period in the NWS Mount Holly coastal waters forecast before committing to the run. The canyon chain north and south of this port is covered in the Northeast blue marlin regional guide (see also the Atlantic Northeast fishing guide).

Who fishes for blue marlin out of Cape May
Charter crews and the tournament fleet fish these grounds.
Charters
Two local operations list blue marlin:
- Common Sense Sportfishing in Cape May
- Captain Mark, on the Captain Experiences listing. The 16-hour canyons offshore trip runs 60 to 70 miles to the canyon and shelf grounds, and the listing credits Captain Mark with 56 years of experience.
A charter is one way to see the run and the grounds before taking your own boat out. It does not promise fish.
Tournaments
The tournament fleet works the same water in July and August:
- Cape May Marlin Tournament: usually July. See the Cape May Marlin Tournament page.
- South Jersey Yacht Sales Offshore Showdown: usually July.
- The MidAtlantic: usually August, with blue marlin as a named division.
White marlin and other billfish share these July and August divisions. See our billfish fishing pages for more.
