But what do you do if you hit your head on the notebook lid when you
try to open it, then reel back in shock and your handheld gps flies
out of your hand? Then, as you over-react again, reeling forward,
knock your head on your binnacle and smash the compass? Then what do
you do? Huh? Huh? At least my paper charts will float long enough for
me to do an MOB on them.
