This is exactly the sort of case where people lose situational awareness. They 
were worried about other things. The captain was trying to break records 
getting that vessel out of the shipyard on little sleep, and he was going out 
of his way to make the "aviation assessors" happy (probably because that 
meant he could get to sea one day sooner).

So why didn't they worry about the Voyage Management System complaining about 
a position discrepancy between GPS and (presumably) INS? My guess: the system 
wasn't fully functional yet. This was a trials cruise, and they probably had 
some other reason to be suspicious of the navigation system. They entered 
incorrect initialization data for the INS and the VMS noticed the discrepancy 
right away (damn computers). What does this tell us?? Ironically, trust the 
electronics. They're probably right, and no matter what, drop anchor and stop 
rushing things. Computers can be wrong, but they are never sleep-deprived, 
and they don't worry about the happiness of aviation assessors, and they 
don't care about their careers.
