The Beach Haven Charter Fishing Assoc. has a couple of boats listed that could fill your needs . The Miss Beach Haven and the Star Fish . I work/fish out of Pt. Pleasant so we are a couple of inlets too far north for you .
There might be some YFT/Mahi's up by Late July . You might look into an Offshore troll trip . The Spencer Canyon isn't too bad a run from Beach Haven The Mahi hang under the lobster floats on the edge of the Canyons.
