ABSTRACT:
A boat hull is provided including fore and aft hull sections pivotally interconnected for relative angular displacement of said sections about a horizontal transverse axis between predetermined limits. Connecting structure is provided and interconnected between the sections and adjustably yieldingly resists relative angular displacement of the hull sections. In addition, the connecting structure is operative to adjustably vertically position the axis of relative oscillation of the sections relative to the fore section and the fore and aft sections include generally longitudinally straight adjacent bottom surface portions with the bottom surface portion of the aft section being spaced above the level of the bottom surface portion of the fore section, even when the axis of relative oscillation of the sections is adjusted to its lowest position relative to the fore section.
