jsut ran across this and dont' ahve an ide what it is. i do know that
it has something with marine navigation, but i have no clue what it
does and i confess I'm not educated or experienced enoughto know what
it does and what it's good for. all i see is that it's an award winner
of some sorts.

Wayne?
