I should like to ask if nevertheless you have tried to compare 
the experiments with thin ship computation, and I will go farther than 
that. I think that the slender body theory can be shown to be a kind of 
particular case of the thin body theory if you let the draft go down to 
zero, and I wonder if your theory also can be derived as a particular 
case of the ship approximation.

In fact I have a comment somewhere in the paper on that. If 
you think back to the boundary value problem that I solved, I had the 
same free surface condition which everybody uses in thin ship theory 
and I had the same body boundary condition which everybody uses in 
thin ship theory. The only difference was that I dropped one term from 
the Laplace equation. So to the extent that that term is small then they 
ought to give identical results. Of course, that term is probably not 
small and that is part of the reason I am looking at it. So Il am not 
quite sure what the difference would be.
