Thanks for the info Geosub, that certainly sounds like an interesting idea.
I'll have a look around the files and add a couple of ships and see what results I get.
Anyone else tried this, editing the RND file? Should I be setting all vessels as 'class= (blank)', or just merchants?
As I say, I'm not usually one for this fine-tuning, as it has produced CTD's in the past so I usually just download mods that work with GWX, but if this does work I'm all for it!
Cheers!

EDIT - I've just opened the Campaing_RND.mis file using Wordpad - talk about confusing! - Where do I start???
