Get out there and chum em up. PRobably could get them at the East Lump not too far from cape may. Or try trolling, instead of slammer blues you might find yourself tied into a nice mahi, wahoo, tuna, or even a marlin. ITs not that far out so i am told.
When I fished out of Cape May, we would troll all around five fathom light and five fathom bank- if I remember correctly, it is approx. 15-16 miles offshore.
We trolled them top and bottom. Hoochies on top and #5 clark spoons on the downriggers.
