A watercraft hull includes a lower portion, an upper portion, and a strake positioned between the lower portion and the upper portion. The lower portion may include a bow portion having a v-shape defined by a keel and sidewalls extending upwardly therefrom to the strake and an aft portion having a tunnel formed therein. The aft portion may be defined by a pair of opposing sidewalls extending downwardly from the strake to a bottom portion. The tunnel may be defined by a pair of opposing tunnel sidewalls that extend upwardly from the bottom portion to a tunnel top having a center rib. The lower portion may also include a medial portion that transitions the bow portion to the aft portion. The medial portion may have a vacuum chamber extending between and transitioning the keel of the bow portion to the tunnel formed in the aft portion.
