1. A planing blade for a hydrofoil, comprising:
a framework defining a generally wing-shaped body, the framework having
an upper surface,
a lower surface, and
a front edge between upper surface and lower surface, the front edge curving from a central point to two opposite side edges,
a plurality of voids defined by the framework such that void has an upper opening at the upper surface of the framework and passes through the framework to a lower opening at the lower surface of the framework;
an integral cover, comprising a material which fills the plurality of voids and covers at least a portion of the framework to define a continuous upper surface and a continuous lower surface of the planing blade.
