    Re: Fw: Grounding of cruiser PORT ROYAL

    Hi Lu
    
    Roger that!  I wasn't blaming the electronics, rather the crews' reliance on 
    the electronics without consideration of other factors.
    
    Best Regards
    Brad

    I wouldn't blame the problem on electronics, but rather on violating the
    fundamental rule of navigation -- to use ALL available information.
    Silt indicating the ship was operating in shallow water was ignored.
    Alarms indicating a disagreement between the GPS and inertial systems
    were ignored.  Even having a competent deck watch instead down below
    serving galley duty was wrong.   I suspect the captain was under
    pressure to return the Port Royal to service quickly despite delays in
    its shipyard work (two weeks, according to the article); he gambled and
    lost on shortcuts in returning the Port Royal to operational status.  I
    guess there's a thin line between being a bold leader (which is what
    gets you promotions) and a stupid one...

    little thought in their heads about how the position might be wrong, even 
    though the electronics warned them about a 1.5 mile difference between the 
    inertial (laser ring gyro) system and the GPS system.  Why they thought that 
    the inertial system would be better than either the GPS or the Mark 1 Eyeball 
    systems astonishing.

    officer's careers are ruined.  For those that were actually culpable, they 
    deserve the punishment, as they could see that they weren't in the right 
    spot.  What were they thinking?  One of those articles states that they could 
    see silt being churned up (shallow waters) and that they could see fixed 
    locations on land.  At what point did they think that was OK, especially 
    after the electronics warnings about GPS errors.
