aft of the sphere and were 6 inches wide, l/l6 inch thick, and had a span of 

 2k inches. The lower forward quadrant of the vertical longitudinal plane of 

 the sphere was slotted to permit the passage of the mooring line to the cen- 

 ter of the sphere. Figure 5 shows the general arrangement of this buoy. 

 After the sphere had been immersed during several tests, separation occurred 

 between laminations and the layers became displaced relative to each other, 

 which produced a corrugated effect with irregularities as great as 1/2 inch. 

 This necessitated the construction of another full-scale model at the Model 

 Basin to complete the required tests. 



Photographs of the models are shown in Figures 6, 7» 8, 9> and 10.
