Abstract:

The equations of steady free-surface flow with gravity past a ship are expanded in a small Froude number perturbation series. Expressions for the vertical force and the moment and the sinkage and trim, correspondingly are derived up to second order. Two examples of flow are solved to first order a two-dimensional flow past a Rankine half-body in shallow water and the three-dimensional flow past a slender body of revolution. Author
