My point was that Sola TS should have noticed and plotted HI before they did because I think she was visible on the radar from the time when they left the pier at 03:45. I do not know if any of the northbound vessels did plot her.
When it comes to manoeuvres, I think Sola TS did what could be expected from her, close quarter situation is normal many places.
I think that there was mistake from HI, VTS, and Sola TS that in the end resulted in the collision.
