After such a positive comment, ....
The patch, downloaded from the site, contains the collision boxes for the Dover environment and for Pride of Rotterdam. I have tried the collisions between PoR and this specific berth, and everything is fine on my system, the ship doesn't enter in the quay.
So, it must be something else, and as Apejens' version is not Steam, the patch should be the good one, I think. Perhaps some more explanations about the malfunctioning, when and how, could help to find its origin.
Regards,
Luc
