Hi all:
here's an image of the Cutty Sark when I had her set up as AI in FS2002 (the USCG cutter in the background is AI too). Unfortunately, the Cutty was extremely "tippy" and we could never get the contact points right to make her fully stable in the water. Haven't tried it again in FS9.

As for the strange wake, I've noticed that when setting up FS9 AI floatplanes with the FS2002 water effects files - they don't stay on the water but just lift up. I've since switched to the water effects (wake and waterland) that came with the Maule amphibian version and they work well. I can provide more details if you want me to.
Cheers, Holger
