The results are shown in Fig. 11 for a Froude number Fn = 0.20. For the other 

 Speeds a similar result was found. A numerical comparison is given in the Ta- 

 bles 2, 3, 4 and 5. It may be concluded that the section results are in agreement 

 with the values for the whole model. No influence of the gaps between the sec- 

 tions could be found.
