Okay, I was a sailor. In fact, my job was navigation. Since you asked, I'll tell you. You have no idea what you're talking about.
OK, change that to ALMOST always. If, as you claim, I don't know what I'm talking about, then the counter-claim is that the sun is NEVER visible during full overcast.
I will not debate this with you. Too many years sailing out of Boston Harbor, in weather fair and foul, have taught me otherwise.
