jeffies, you said it all with:

I haven't used RDF

that we knew when you said it was accurate on a recreational sailboat to 2
degrees.

Everything I knew about RDF came from the Ray-Jeff manual,

if you hd paid attention, and thought things through, you would not have been
plowing through the granite ledges blindly in fog trusting your RDF to keep you
safe.

God takes care of fools and little children, jeffies. you got lucky. other
people didn't.
