A wake control apparatus for adjusting the trim of a watercraft to selectively raise and lower the level of the wake produced by the watercraft. The apparatus comprises a pair of hydrofoils which are pivotally connectable to the watercraft in spaced relation to each other. Mechanically coupled to respective ones of the hydrofoils is a pair of actuators which are connectable to the watercraft. Each of the actuators is operative to pivotally move a respective one of the hydrofoils between neutral, first and second positions. The apparatus is attachable to the watercraft such that each of the hydrofoils is moveable by a respective one of the actuators about an axis which extends in non-perpendicular relation to the longitudinal axis of the watercraft. When the apparatus is connected to the watercraft and the watercraft is propelled within the water, the movement of each of the hydrofoils from the neutral position toward the second position causes the aft end of the watercraft to be drawn downwardly into the water to increase the level of the wake produced thereby. Conversely, the movement of each of the hydrofoils from the neutral position toward the first position causes the aft end of the watercraft to be elevated within the water to reduce the level of the wake produced thereby.
