Be careful though....You are not the only one with radar out there.
I once tried to find a contact with radar in foggy conditions and suddenly had a destroyer bearing down on my boat trying to ram me. Actually an amazing sight while standing on the bridge yourself.
The worst thing was, my watch didn't even report him

so without being damaged and after he had disappeared into the fog again my crew on watch were looking at me like '' Where did who go ? ''

You crazy nutter...
