2843. Streamlined Buoy 



A streamlined buoy has been designed for use as a sono-radio or radio-current buoy. 

 Preliminary use of^this buoy indicates that it may have many advantages where strong

currents are prevalent. Figure 52 indicates its general appearance. Construction 

 specifications and drawings are available. The buoy itself weighs 250 pounds and dis- 

 places 1,450 pounds; fully equipped as a sono-radio buoy it weighs 450 pounds. 



This buoy maintains an antenna nearly vertical, well out of the water, in a 

 comparatively rough sea and strong current, and it floats steadily without yawing. 

 When used as a sono-radio buoy, it seems to produce no objectionable water noises to 

 be picked up by a hydrophone. The strain on the anchor line is less than with con-
