    Re: Looking for references on "aiming off"

    Hi George H.
    While I do not want to burden you with extra work , I "know"?(from your past 
    posts) that you are able to give this chap more practical techniques that you 
    have used in your sailings...say to France, in order to get him moving in the 
    right direction. (Tidal currents, wind age factor, seamanship , fixes, 
    reliability of charts use of Pilot Charts etc.
    ( You might also want to touch on the easting-westing routine )
    Hope you don't mind my 2 cents worth .
    Kind regards
    Irv
