I have been following your project for several years, having served on the Oklahoma City from 1971 to 1974.
I don't know where you plan to take the Okie Boat from here, but there is currently a project to bring realistic AI ship models to the new Microsoft Flight Simulator 2020 that you might be interested in. I know I would love to see the Oklahoma City sailing again.
The project page is at this address: https://flightsim.to/file/9529/global-ai-ship-traffic-msfs-v1 and the developer's name is Henrik Nielsen.
I thought perhaps your ship might be too highly detailed for this, until I read a post by another developer who has contributed his model of a historic paddle steamer to the project: https://www.avsim.com/forums/topic/589840-henrik-nielsons-global-ai-ship-traffic-for-msfs/page/38/
