    Re: The Darn Old Cocked Hat - the sequel 1
    From: Bill Noyce

    Although Gary addresses this somewhat by "allowing several SD's" I think it's important to emphasize a fallacy in William Hawes's procedure:
    > Although perhaps not mathematically robust, when I was in the navy I was taught,
    > that when in coastal or pilotage waters, to pick the worst scenario/most dangerous
    > position in the cocked hat.

    This ignores the possibility, which I hope we all accept, that the true
    position is outside the hat -- the whole point of this discussion.
    If a reef were 1/2 mile outside the cocked hat, should we feel safe?
    Unfortunately, teaching to choose the worst position "in the hat"
    seems to imply we should.
