The skipjack Rebecca T. Ruark has worked the oyster beds of the Choptank in three centuries. Since 1951 she's had two captains, Emerson Todd of Cambridge and Wade Murphy, Jr. of Tilghman Island. The latter's son, Wade Murphy III, has grown up aboard her. In
2014, she was still working under sail, the last full-time sail dredger on the Chesapeake. Here, Wadey Murphy III culls oysters, separating live, legally sized ones, from undersized and shell.
