The lack of rigour in treating the radiation condition used in the more popular methods described in recent years was criticised by Bail Suggestions that the approaches were nearer to art than science were quickly refuted by the more pragmatic users of the methods since the experience has been that the methods do provide good engineering predictions provided the algorithms remain stable. There was general agreement about the desire to use higher order panels to resolve the divergent wave system and to better model the larger gradients in the bow region (Yim, Larsson, Mori, Baubeau)

The existence of solutions to the potential flow formulation of the wave resistance problem was discussed at some length in the context of instabilities near the water-line. In the real world, we know that spray and wave-breaking occur -especially near the bow; both viscous and surface tension effect are present (Jensen)
