    Sam.  I’ve already sent off two messages to NavList this morning, so I’ll leave answering this one until tomorrow if you don’t mind.  I’ve also got to revise spherical geometry first.  As I said, it’s all bagpipe music to me at the moment.  I can barely remember “some people have coal black hair through perpetual brushing” and “all silly tabby cats”.  I see Bowditch is available on-line?  It’s more popular in the USA than the UK, so I’ve not looked at it before.  Please will you give me a chapter and a paragraph number rather than a page number?  It’ll be easier to find the correct section that way.  Dave

    Dave,

    Here are the coordinates;

    Departure point- N 39d 58min  W 075d 12.2min

    Destination point- N 41d 43.5min   W 075d 02.5min

    The formula i use was mentioned previously and found in Bowditch page 332.

    The problem could very well be my calculator. It probably has some sort of setting that messing things up.

    Sam L.
