Adjustable planing device mounted midship on a pontoon boat to provide lift to the pontoon boat, reduce drag, and improve steering. Adjustable planing device includes a planing device having a connector member with a hinge that is rotatably attached to a midship region of the boat wherein the planing device is pivotable about the hinge by a powered actuator such that a portion of the planing device comprises a subsurface volume below water level. Optionally the planing device is buoyant. The planing device is adjustable vertically relative to the boat to vary the depth of water displaced by the planing device. The adjustable planing device is movable along a track mountable to the bottom of either the boat or cross-members wherein the longitudinal position of the planing device is adjusted. The cross-sectional shape of the planing device varies from a tapered shape in front to a flatter shape in rear.
