    Gary,
    
    > Some radio waves do penetrate into the sea
    
    yes, very long ones. I don't know the details
    (how deeply they penetrate) but I know that
    the Germans attempted to base radio connection with their submarines
    on the very long waves. Possibly for this reason.
    
    My previous message explains why such long waves are not likely
    be of use for precise navigation.
    
    Alex.
