Claim:
1. An inboard water-sport boat comprising: a hull having a transom; and a foil coupled to the hull and movable between an undeployed position, a first deployed position, and a second deployed position, wherein the foil is configured to produce a lifting force when in the first deployed position as the hull moves through water, wherein the foil is configured to produce a downward force when in the second deployed position as the hull moves through water, and wherein at least a portion of the foil is disposed above a bottom edge of the transom when in the undeployed position; one or more actuators configured to move the foil between the undeployed position, the first deployed position, and the second deployed position; a sensor configured to provide a signal indicative of whether the boat is planing; wherein the one or more actuators position the foil at the first deployed position when the signal of the sensor indicates that the boat is not planing, to produce a lifting force that helps the boat to plane; wherein the one or more actuators automatically move the foil from the first deployed position to the undeployed position or the second deployed position when the signal of the sensor indicates that the boat is planing.
