    Re: Tides by bearing of the moon

    Hi Dave.
    
    Next, try some place more tropical. Hawaii perhaps? :-) That should show 
    significantly worse behavior with respect to azimuth.
    
    I wrote some code a few years back to do tidal calculations. It's much shorter 
    than the widely available X-tide code and only marginally less accurate: 
    http://fer3.com/arc/m2.aspx?i=100454. 
    
    Here's a question that's been in the back of my head for a long time... which 
    is a better predictor of tide times: the local hour angle of the actual Moon 
    or the local hour angle of the mean Moon (which we can imagine moving along 
    the celestial equator with constant angular velocity)?
