    SS61 course to steer
    From: Patrick McVey
    Date: 2000 Apr 07, 8:19 AM

    On leg 61 departing Rio. On the question of Course To Steer.
    1) Correct me if I'm wrong: This is the course one would steer which accounts 
    for tidal stream, .6 knots drift at 185d set. Correct. THEN, one applies the 
    magnetic variation & compass deviation. I can get the CTS but I don't know if 
    one adds the compass corrections.
    
    2) I am using a graphical method for solving tidal stream. Can someone point 
    me to a mathematical formula. I didn't readily see one in the 4mulas zip 
    file.
    
    Thanks for the input. Its good to be back after some absence. Thanks to the 
    group members for this tremendous resource.
    Patrick
