Grabbed it last night and installed right away.
Nothing short of stunning, Henrik!
BTW, for anyone who likes retro AI boat traffic and wants to keep the density of the original FSX/P3D (in my case P3D) boat traffic file but doesn't want the default modern ships, I'd suggest cherry picking some of your favourite cargo and cruiser vessels from this pack after using AIBTC to decompile, and changing the assignment in the boat file, then recompiling. This way you get all the original traffic density PLUS all that Henrik's traffic bgl's add.
Took me less than an hour, and now in addition to the added traffic from Henrik's files, you keep the extra volume that the original default traffic file contributes, only now with whichever of Henrik's boats most suits your fancy. I kept the general categories, replacing the default tankers, cruise ships, etc. with Henrik's classic ships of similar function - bingo. Instant (extra) AI boat traffic. I can share the substitutions, if people are interested. The only hard part was deciding which of the gems to pick - there's so many good ones. Thankfully you're still going to see them all in Henrik's traffic files - they're all works of art. But if there's ones you'd like to see more of, then this approach will add retro traffic.
Note, unlike Henrik's traffic files which are are route-specifically accurate, doing this will add vessels to routes that aren't likely to be super accurate. For example, I replaced one of the default large cruise ships with the Canberra - because it's so lovely and graceful. So I'll see her on routes she likely never sailed, but ... whatever - these ships are too gorgeous to only occasionally stumble across.
So a huge thanks again, Henrik!
