I'd tend to agree with you. Mind you, radar can be *very* good. We have
2 on our icebreaker and I've steered through heavy sea ice using the
radar image to see where the leads are. Lotta fun and it doesn't really
matter if you turn a little wide or tight since it's OK to crunch over
stuff in the way.

That situation seems quite different to doing the same thing in a busy
waterway.



Anyway, if damn fools are considered as worth the trouble of saving,
then running at 25 knots on radar only in heavy fog isn't prudent.
Personally, I wouldn't regard anyone stupid enough to go out onto a
busy waterway, in heavy fog, sans lights, radar reflector, radar, sound
signals, radio and in a hull that is a poor radar reflector as worth
saving. Anyone that stupid is a hazard to navigation and we're all
better off without them.

I don't really disagree with you.

I'm simply saying that I don't think that travelling in a busy waterway at
25 kts using radar alone is semsible - in any state of visibility.
