These results, coupled with earlier findings (Murphy and 

 Shoraura 1953), indicate that the actual depth reached by the line is 

 a function of a complex of factors. Only one of these is readily 

 ascertainable and that is the distance between buoys. Since this 

 distance governs the maximum amount the main line can sag down between 

 buoys it gives the maximum possible depth that the line can reach. 

 During Cruise 11 of the Manning the deepest hooks could have been 

 fishing at about 550 feet (table 17), with the other hooks at lesser 

 depths, Even this figure is approximate as there is variation in 

 buoy distance between baskets and there is probably variation within 

 a basket while it is soaking.
