    Re: sextant without paper charts

    The US Power Squadrons continue to teach sextant navigation as the
    core of their Navigator grade. I am teaching this course at the
    present time. There are approximately 700 students across the US
    presently studying this course. A smart skipper would use the NASR
    method in the Almanac or use his computer and NAVCALC which solves the
    determination of Ho and Zn from which the intercept is calculated
    Simple.
