tested in the TMB 1800-ft basin. For example, information is at present available that shows 

 large apparent discrepancies between the motion results obtained for 5-ft models tested in the 

 TMB 14:0-ft basin, and those obtained for 20-ft models tested in the 1800-ft basin. More model 

 tests are required before definite conclusions can be reached with respect to the reasons for 

 the discrepancies. 



The five models were tested in a variety of wave conditions, but only those motion data 

 corresponding to mild or moderate conditions were chosen for the comparative study. This 

 means, in effect, that tests in waves whose heights were greater than l/40th of the wave 

 length were excluded from this investigation. This was done so that nonlinearities introduced
