Claim 19:
20. A foil system for biasing a cable of a towed marine array comprising:
a foil defining a foil shape having a leading edge and trailing edge;
a first through-cable extending through the foil along the leading edge;
a second through-cable extending through the foil along the trailing edge;
a first actuator configured to tension the first through-cable; and
a second actuator configured to move the tensioned first through-cable from an unselected configuration to a selected configuration, wherein:
when in the unselected configuration, the tensioned first through-cable cooperates with the second through-cable to maintain the foil at a substantially neutral angle of attack; and
when in the selected configuration, the tensioned first through-cable cooperates with the second through-cable to maintain the foil at a positive or negative angle attack.
