CONCLUSIONS 



From the analysis of the test data on Buoys 1, 2, and 3 it was pos- 

 sible to select that buoy which would meet the requirements established by 

 the Woods Hole Oceanographic Institution (1). 



The requirement that the drag coefficient remain fairly constant 

 for a range of Reynolds numbers from 1.0 x TO 5 to 7>5 x TO 5 was satisfied by 

 both Buoys 1 and 3; see Figure 19. The other requirement, that the buoy se- 

 lected be reasonably stable in currents up to 5 knots, full-scale speed, was 

 satisfied only by Buoy 1 . The full-scale model of Buoy 1 was selected as the 

 one most nearly fulfilling these requirements. 



Buoy 1 will be further developed by the Woods Hole Oceanographic 

 Institution.
