There's also the possibility of multiple bouys, and possibly things  
like suspending the antenna (and radio?) from a balloon tethered to  
the bouy (or maybe I'm thinking of just an anchor!) if this is for an  
event of some kind (I'd make at least the radio part floatable, and  
design it so that when the balloon comes down the antenna will be at  
least slightly above the water to make recovery easier).

But I wouldn't listen to me too closely - after all, I'm a long ways  
from any large body of water.  I can shout across every body of water  
within an hour drive from me!
