A Dawson-type or rankine singularity free surface model is employed in which source panels are distributed over a local portion of the free surface and a linear free surface boundary condition is applied at each panel. The steady sinkage and trim of the ship can be modeled automatically by balancing the ship's hydrostatics with the computed heave force and pitch moment and iterating the SLAW calculation for the sunk and trimmed hull.
