Story - supposed to be true.

Two yachtie types buy GPS's and they are determined to try them out.

Sailing along, on auto helm, below decks, on the radio to each other,

"And what does your GPS give as a postion >

" Lat this etc ", down to 2 decimal places of seconds.

" Funny, so does mine !"

"Crunch !!!!!" - Loud expensive noises !!!

" MAYDAY, MAYDAY, MAYDAY, this is Yacht......."

BTW The secret is not steering to a waypoint, but knowing when to stop steering to a way point !

Gareth - In cynical mode.
