ABSTRACT:
A boat hull construction having a bottom formed with a central longitudinal surface and side surfaces spaced on either side of the central surface. Both the central surface and the side surfaces are flat in a cross sectional direction, and the side surfaces are separated from the central surface by upwardly arched channels. The three parallel flat surfaces enable the boat to plane at lower speeds and provide improved lateral stability.
