trollling around on a small yacht in fog and meeting it would worry me,

This not a reflection on the crew, just my own feelings. I think it is
probably totally impractical in a working environment when time is fuel is
money but I would rather everyone trolled around at speed to suit conditions
that would let them avoid collisions visually. One of my old teachers used
to warn us of 'radar assisted collisions', I suppose I carry this concept to
this day, probably reinforced by own lack of experience using radar and my
lack of exposure to the use of radar at the hands of a really experienced
operator.

Most "radar assisted collisions" occur because someone didn't plot the
target. Using the EBL/cursor and range rings or VRM, is not plotting.
Problem is, few recreational boaters have the ability to plot, many
"work boats" don't either ....no excuse for ships.
