Okay, since my primary objection was to the use of "always", I'm satisfied. Although my experience has been more along the line the sun is sometimes visible through a full overcast.
To let you know where I'm coming from, the majority of my sea time was the W Pacific, but I've been in every major basin except the Arctic and the S Atlantic.
Also, in the Navy on ships without aerographers, which was every ship I was on, navigation was responsible for the hourly weather observations. So between celestial and weather obs, I've spent a lot of time looking at the sky at sea.
Thank you for your service, sir.
