A preferred planing foil apparatus (10) for use with a pontoon boat (12) includes mounting structure (32) for connecting a planing foil (30) to the boat (12) with the foil (30) positioned between and spaced from the pontoons (12, 14) generally amidships and straddling the transverse centerline of the boat (12). The foil (30) is also positioned between the waterline (62) and the lower surfaces (64) of the pontoons (12, 14) when the boat (12) is at rest so that foil (30) rises toward a planing position on the surface of the water as the boat (12) is propelled therealong in order to lift the boat (12) and reduce drag.
