    Re: Line of Position Fix-Submarines

    About two weeks ago I stumbled on the Bantam war book titled "Clear the Bridge" by Admiral Richard O'Kane.  The book is about the  5 WW II patrols of the submarine  USS Tang. Admiral O' Kane  survived the sub's sinking on its last patrol.
    The book is technical, which I like. and reads like a very long report with all sorts of details. O'Kane frequently mentions their course changes, morning sights, evening sights etc. How close they were to their dead reckoning.   It is a good book especially if you are interested in WWII submarine technology and tactics.  I assume this book is readily available; if not let me know and I'll drop it in the mail and we can pass it around.

    I am glad to see you weigh in on this topic.  It gives me an opportunity to ask a follow up question regarding fleet practice with regards to the observations.

    How many stars (bodies) were used in the determination of a twilight fix?  Did the actual practice match the published advice to fleet officers in training at the academy?

    Byron to Debbra, If you have 'you tube' go to "navtec333" I have a complete
    video on filling in the sight form (229)and plotting the fix. It also talks about using a star finder. The best time to shoot stars or any body is when the horizon is clear and visible and the body's near 90 degrees for two or well spred for more than two. practice makes nearer to perfect.
