Ian, the reason for this split-up was, that I wanted to seperate between "Working vessels" and Tugs, as the description "Working vessels" could be Tug, Anchor-puller, Offshore-Supply, Fishery-patrol....
But I assumed that most are in tugs... and it looks like I was right... (don`t ask my lady, she`ll tell something different either)...
So it is interesting to see the differences between the German and the British/European/American/Australian/ anybody-else-I-don`t-want-to-forget-scene...
I`ll give a clue when the poll is over.
Regards,
Jörg
