    Silicon Sea answers should be worked out in what ever method of Dead
    Reckoning or Sight Reduction you are comfortable with. Most Silicon Sea
    problems are based on a specific Dozier Rhumbline formula. Answers can vary
    from the Silicon Sea answers, but if your answer is with in +/- 5 degrees or
    +/- 5 miles it is correct. Guys this is practical marine navigation, we are
    not trying to place an object in orbit.
    Great Circle is a special case and not very practical for small boat
    navigation. When a Great Circle answer is required the Silicon Sea question
    will state it.
