    I have a friend who engineered the very wide screen TV display for a tug
    boat "flight simulator".  He told me that any kind of change to a large
    ship, like an oil tanker, needs to be made miles in advance of when it's
    needed, so the extremely high cost of the "flight simulator" was justified.
    Have Fun,
