I'm not sure if this helps but can you put a smaller vertical near the
water's edge and then run a top loading wire angled to the tower top?

Kenny,
It's not easy and in fact I haven't done it for anything lower than 40m. It
would be very interesting to compare something at the water's edge to what I
have now. The shoreline runs SW-NE - I think about 215-35. The question
is how much better it would be if the antenna were right next to the water.
I don't have a clue as to whether it would be significantly better or not.
Of course I'm talking about Europe.
If you drew a straight line 45 degrees from the tower it would not be over
water until you went 15 miles, yet I'm robably over water in less than 100
feet if you go about 25 degrees from the antenna.
I cannot imagine that I have no significant improvement to 45 degrees
because a straight line to 45 degrees does not go over water for many miles
but I don't have the knowledge to prove it. I would bet, however, that it
would be very difficult to match the signal to locations 45 degrees with a
single element located a quarter mile SE of where my tower is located.
Maybe someone has some idea of just how much better my signal would be if I
had a 160m vertical 65 feet closer to the water? If I were convinced it
would be significantly better it would be a safe bet that I would find a way
to accomplish it - at least for on-site 160m DX Contest operations.
