Figure 3. --Albacore tuna catches by the Hugh M. Smith and the charter 

 vessels during the Northeastern Pacific Albacore Survey. 



Eight of the charter vessels started the 

 NEPAS survey on schedule on July 22, 1957; 

 the ninth started on July 23. All vessels conn- 

 pleted the survey of their assigned tracks on 

 either July 31 or August 1 except the Tuna 

 Clipper and the Lynn . The fresh-water supply 

 of the Lynn became contaminated with salt 

 water and she was forced to withdraw from the 

 survey about 150 nniles fronn her starting point. 

 The Tuna Clipper encountered heavy weather 

 at the start of the survey and was forced to 

 return to port in a lesiking condition after com- 

 pleting 30 nniles of her track. Several of the 



other vessels sustained storm damage (e. g., 

 the Luwella broke both trolling boonns and her 

 radio antenna), but they were able to maJ^e 

 repairs en route and complete their tracks.
