T&T: GPS Error

[Pascal Gademer]

there have been cases of uncommanded turns when on AP, sometimes caused by 
bridges, large metal objects, etc...

i woudl never run the AP in a channel...

couple of years ago, someone posted the pictures of Sea Ray Sedan that ran 
up a mud bank at cruise speed on the guld coast.  Boat suddenly turned 90 
into the shoreline.  BIG hole with jsut the deck remaining on top.  forgot 
the story but i think they blamed the AP
