Rebar stakes lead the way from the Patricia to the Miss Karline and the boulders. More stakes run from the boulders to Billy's Barge. The radio antennas lie, unstaked, just south of the boulders. The Matthew Lawrence is located just south of the antennas. Many wrecks are marked on diving and fishing charts, and even a few on regular marine navigational charts.
Divers can also find wrecks by asking other divers.
Dive shops and clubs are good sources of information. Regardless of how easy it is to obtain the coordinates of a wreck, a Loran C or GPS is necessary to get there. Once the charted position is reached, the fathometer or depth sounder can be used to pinpoint it. Never anchor over a shipwreck. Anchors can damage wrecks, and have been known to pull wooden wrecks apart.
