You will not see any fog
is nice to have, but would not be high on my list of priorities.
The standard of ship watch keeping in this part of world seems pretty woeful. AIS will help, but don't expect miricales. A simple visual watch is more than adequate to avoid the traffic, however.
Radar generally just shows they are going hit you like a visual lookout will.
The biggest advantage of radar is to overlay a radar image overlay on top of map to highlight the errors in charting. Very useful for night approaches to anchorages
, but if you restrict yourself to entering most anchorages
in daylight the water
is so clear that a visual lookout is generally the best.
