Dr. Landweber's comment on page 10 is right, but the 
measurements show that the wave along the mid-ship is almosta 
two-dimensional wave. The blockage correction is a very interes- 
ting problem which has to be considered. The 14-ft and 10-ft 
models appeared to need some blockage correction in the lowa tank. 
It is interesting that the 6-ft model and the 20-ft model agree very 
well.

All the results presented in this paper are very interesting. 
And especially, I think it is exceptional to know both distributions of 
pressure and shear stress ona hull. In sucha case, I would have 
been tempted to check, by integration, the values of the total resis- 
tance and its two components that have been measured by other means, 
May I ask the authors whether they did make such a verification. 
Thank you.

Because of time, the actual integration of the pressure dis- 
tribution and shear stress distribution has not been done. We want 
to improve our computation methods for the potential flow as well 
as boundary layer first and the actual integration can be done if we 
have time, and probably will be carried out in the near future. It is 
not a major point of our paper.
