    Coming from a professional mariner background myself. I wonder more what
    the impact to the average boater is.

    My concern is that they will say things like 'well the big boys don't need
    paper maps, so electronic navigation is all I need to ever know)

    I am fearfull it gives them a false sense of security.

    There is no substiture for training, situational awareness and common sense.

    Hank.
