Ozer,

At AA7JV I have an antenna right by the sea (on the 
sea-wall, 1.5 meters above the water) and I used an 
inverted L standing at the edge of the sea on 5K0T. From 
experience with these and similar antennas on VK9WWI and 
C6AGU -- where we tried radials -- I can tell you with 
certainty that you do not need the radials over the sea 
water. You may want to instal some on the land side, but 
even that is of questionable value. Just connect your 
feedpoint "GND" to the sea-water. Please note however, 
that throwing a cople of wires into the water will not 
give you a decent ground. You need lots of metal surface 
in contact with the water. I use a 30 cm wide stainless 
steel sheet connecting the antenna ground to the sea 
water. It works!

GL and 73,

George
