Hi,
I read the articel in Shipsim Magazine Issue 1, by NathanC,  about Pride of Rotterdam . 
In the third part he write this:
 
" The 1.4 dynamics of the ship are brilliant, the ship
is very manoeuvrable with bow thrusters and the
ship turns very quickly with the rudder. I am not a
fan of the 1.4.2 dynamics as the ship handles very
sluggishly, but you cannot blame VSTEP as P&O
very helpfully didn’t provide the developers with
any handling characteristics."
What is 1.4 dynamics ?  
What is 1.4.2 dynamics.
What is the difference ?
Have not read  about it before. But otherwise it is giving a good example of how to handle the carferry, howe to turn, move, dock in the Magazine. This in the following parts of the article.
Appreciate an answer.
Regards
Nils
