Hi,
If the question was adressed to me, I can tell you, that I've spent more than 20 years on the sea (on the ship's bridge):-)
So, I know these problems very well.
In my opinion, every captain should do everything he can to avoid the collision.
It's truth, that 90% of collision and casualties are caused by the human errors.
A lot of mates are fascinated in GPS, but I always telling him: what would you do, when GPS will be shut off?
But I can't present my opinion about collision of ECE and GROT-ROWECKI, because I don't know anything about it.
Regards,
MJK.
