Thank you all!
I think there all slightly different, i'm a navy engineer and sailed on all kind off ships. And even there is a difference in the length en curving of the ship from the same classes. Sometimes even a couple of meters.
If you look at the floorplans from the attachment (300 & 350 model) you see also that the curving from the nose is different drawn.
Mine 350 Le was standing near a other 350 and the angle of the nose from mine was almost verticle.... even so much difference that i was thinking that mine was refitted, but it never had a accident so...
So indeed a head scratcher (lol)
