The operator of that small boat without radar may be foolish or even
foolhardy, or not, but the fact is that boat and operator have as much
"business" being there as you or the QE2.

The problem is with those who think that some another vessel has no
business being there and act as if it is not their responsibility to
take into account the possibility of meeting such a vessel in dense fog.
