design load is conservatively estimated and the load-holding 

 ability of the stop can be tested independently, failure to 

 test under worst conditions need be of no concern. 



Modules 



The present module is designed as a basic instrumentation- 

 carrying vehicle. Only minor modification should be required 

 to adapt it for temperature measurements. More extensive 

 modifications will be needed to adapt it for measurements 

 (sound velocity, salinity, conductivity) requiring a flow 

 of water across the sensor. It is believed, however, that 

 the present design can be modified to provide the necessary 

 ports and vents. 



Handling and Storage Elements 



The feasibility of using the endless-track-type winching 

 machine for handling the modules and faired cable depends to 

 a large extent on the compactness of a unit which will develop 

 the necessary pull. The tests with the Entwistle unit indi- 

 cate that a coefficient of friction of about 0.2 between 

 faired cable and tread may be expected o 



For effective performance, the winch need be capable 

 of inhauling the system with the vessel traveling at a 

 speed of only three knots. For this condition, the initial 

 line tension will be about 10,000 pounds^ progressively 

 lessening with inhaul of the system. If we assume a margin 

 fifty percent greater than the anticipated load, the design
