Abstract
A transonic hydrofield TH has been established which defines the shape of a displacement transonic hull (TH). The hydrofield is characterized in not having curvatures such as shoulders, midbody, or rear quarter, with a deep draft forward and shallow draft aft. In consequence of TH's shape, surface wave-making sources typical of conventional displacement hulls are eliminated. The transonic hull TH corresponding to the hydrofield has substantially triangular waterplane in dynamic displacement conditions, maximum draft forward, and minimum draft aft, and planing lateral surfaces inclined at large angle are vertical to the waterplane.
