RECOMMENDATIONS 



1. Soth manual and digital computer calculations of the section properties of ship hulls 

 (i.e., equivalent beam parameters) should be made for a number of ships. 



2. The digital computer method for obtaining these properties should be generally used 

 if the comparison is favorable or if the comparison between theoretical results (e.g., fre- 

 quencies, mode shapes, whipping response to slam, flutter response), based on the computer 

 program, and experiment is at least as good as the comparison between theoretical results, 

 based on hand computations, and experiment.
