Read this: http://force12inc.com/PCSDAT-002.htm  It describes an 80m 
vertical array overlooking salt water.  They used a pair of "gull 
wing" elevated radials at 8' high.  They note that this radial 
configuration has worked well in several other salt water edge 
operations.  For 160m, you would probably want the radials to be twice as high.

Note that mixing elevated and grounded radials (e.g. laying in the 
water) has been shown to increase system losses and should be 
avoided.  This also means you need a good choke balun at the 
feedpoint to keep the feedline from acting like a ground radial.
