HYDRODYNAMIC DRAG OF SEMISUBMERGED SHIPS
Linearized theory for wave-making resistance is applied to semisubmerged ships. Theoretical and experimental values are compared for submerged hulls, struts, and struts in tandem. Strut forms producing minimum wave-making resistance are calculated at several speeds and waterplane areas for a typical submerged hull. Struts are described in terms of step functions to facilitate an investigation of multiple struts including the effect of drag of decreased wetted surface area.
