I had made one out of "dock" parts from the HarborKit dat file, and they sat fine in the water, but I did not have the "cut-outs" for the side guns and was stuck there. I would also be willing to help out with this. I also used the same "tower" from the Library... lol, as well as a couple of buildings from the HarborKit. Yours looks WAY better than mine... lol - but if no one knew what it looked like, they'd never know the difference. Now you have ruined that...
- but "yes", count me in too, if you need anything!
