    In visual navigation in close waters the triangle on the chart is more 
    dangerious that most think. We are taught by book and school that we can use 
    the center of the triangle and run our DR. from there, also we can use this 
    center position for finding set and drift. Both of these can help leading to 
    a grounding. A little chart work can support this. Any time, with accurate 
    bearing and a little compass error with NAVAIDS within 180 of each other you 
    will get a triangle with you outside of the center. A little chart work will 
    support this. For a complete understanding of this, Bowditch after 1977 and 
    for many year after that or read Franklin Piloting Technique.
