ABSTRACT:
The hull of a generally shallow draft boat comprises a bottom, sides joined to the bottom by chine portions having rounded outer surfaces, and a transom adjoining the stern edges of the bottom and sides. The bottom includes first and second laterally opposite wings, the lower surfaces of which taper downwardly and laterally inwardly from their respective side edges and converge in a shallow first peak which extends partially along the longitudinal centerline of the bottom and whose rear end is disposed forwardly of the stern edge of the bottom. A pair of longitudinally extending keelsons depend downwardly from the bottom on opposite sides of the centerline of the bottom and equally spaced therefrom. A generally triangular delta formation on the bottom has a base disposed adjacent the transom and an apex disposed adjacent the rear end of the first peak and between the keelsons. The lower surface of the delta formation tapers downwardly and laterally inwardly from the respective side edges of the delta formation to form a second peak extending along the centerline of the bottom from the transom to the rear end of the first peak. The second peak is inclined upwardly from the transom to the rear end of the first peak.
