You are making an engineering judgment. You know I mean, when nothing is there, you
have to use your you kind of judgment on that, so you can get this. That is what I am
trying to say. one interesting point that is to be said about this, you see, suppose the ship
is turning, now now you see here, which side the ship is turning is, as it turns here as it
turns here, it is heeling on this side outward. So, you know where you will see this
picture of the ship heeling like that, as it turns, I have got a nice picture on my desk or
aircraft carrier turning this side that is heeling, you can make out that at the heel is in
fact, it almost 10 degree or so, you can make out. Next time you come, I show you I have
got that matter, very nice picture. You cannot make a mistake of the turn because, the
wake will tell you which side it turns, that a real picture.
