FORCE AND MOMENT ON A TWIN-HULL SHIP IN A STEADY POTENTIAL FLOW

The linearized problem of potential flow around a twin-hull ship is solved by two sheet distributions of sources and normal doublets. The thickness problem is solved by the thin-ship approximation, while the lifting problem is solved by a slender-ship approximation. General formulas for the steady hydrodynamic force and moment acting on a hull are obtained as an extended form of Lagally's theorem for two floating lifting bodies. This theory is applied to the prediction of wave resistance of Small-Waterplane-Area Twin-Hull ships. Computed and experimental results are compared and presented.
