How high is that antenna mounted? It would have to be 70' up to have a
horizon at 12 miles. If it was mounted that high you would only be able to
see ships higher than 70' at 24 miles. Those would have to be some pretty
big ships for you to see them at ranges of well over 24 miles, no matter how
powerful the radar.

Antenna's up about 45'. Radio horizon is further than your visual
horizon and can be extended by temperature inversions. The other
thing to consider is the height of the target. A radar reflector a
hundred feet above the water or a large ship can be seen way further
than the horizon because he sticks up OVER it for quite a distance.
