I remember getting our first Furuno gps
that gave the lat and long, MAGIC! It was such an amazing feeling to really know precisely where you were, all you had to do was plot the two numbers and bingo, X marks the spot! DR works, but by the time you throw in some current, cross wind, rough weather, fog, etc it was really little more than an educated guess most of the time:-)) But we always got where we were going, maybe not in a straight line
, but we got there. I still plot the course on paper charts
, but mostly just for fun.
