It certainly should be - but how do you get it at the correct angle?
We've all seen powerboats with the bow sticking way up. And, if the
powerboat slows, as it should in the fog, then the radar is pointing
down. Clearly, if the bow goes up more than 25 degrees at speed,
there is no way to have the radar work at both high and low speed.

Certainly many powerboats will be using trimtabs to stay reasonably
close to proper trim, but I'm not sure we can say "most" have their
radar at a proper angle. And of course, when that sport fisherman is
blasting down Buzzard's Bay in pea soup at 30 knots, is he really
looking at the radar?

Jeff,
On most power boats the radar is angled down so when the boat is
underway on plane the radar is now level.

The beam width of small radars is +-12.5 degrees. Thus, if you're
heeling 15 degrees (assuming no leveling device) you're seeing almost
nothing to windward or leeward. If you're bouncing that much, your
signal is intermittent. And if you're a powerboat at speed with the
bow raised 15 degrees, you could be blind in front!
