Open up like scissors and drag across the bottom of the bay. Used in smaller sailboats. Bugeye: a big, cumbersome boat used to harvest oysters Skipjack: a simpler boat in design, but is easier to operate (one man could do it). Buyboat: had a bushel basket by the sails. Bought oysters from oystermen on the water and brought them to sell on land Cull: used to whack at oysters and determine which were too small to keep.
