Deep water wave have been separated in sea-rescue pictures in the files 

 of the Coast Guard which were taken from the Coast Guard Cutter, and were 

 probably lower in oblique angle than those from the Steel Pier, It is of 

 particular significance that deep-water waves as viewed from a vessel respond 

 to the parallel lines method, for now all that is needed to obtain a ivide 

 collection of data is a simple method for making observations directly 

 without need for photography. Such a device is under development but must 

 still be tested under dynamic conditions where the wave systems are in con- 

 stant motion, before it is known idiether the present design will be adequate.
