    Hi Jeremy,
     
    Thank you for an excellent problem.  It forced me to realize - 8 ZD makes it EAST, just as you wrote.  The nice thing about CN math blunders is that you quickly find the incorrect  solution  is impossible. 
     
    I ignored the speed because  the vessel moved only  4 NM from first to last sight.  I just imposed a northeast bias on my intersecting LOPS. Great sights.
     
    My results... " TA DAH"  , with a very minor drum roll.... 8 * 54 N   109* 44 E.
     
    Stay well and best regards
     
    Bruce

    Hello all,
    It's been awhile since I've done this, but I will post the data on one of the rounds of stars I shot this last time out to sea. I didn't get a chance to shoot too often, but I did get a few rounds in with the cadets in tow.
    B/Rgds,
    Jeremy
