LOL! I am California born and raised, but I thought a paddle wheel boat just cried out for the Stars & Bars!
What are your plans for a paddle wheel boat? Will it be a vehicle? A venue for music? (You can't do both at once, not without a lot of confusion for people who are not sitting or dancing). Making something that looks like your photograph would be a pretty easy build, if you made the floors flat instead of arching up at the ends like that. And used texture maps on big prims for all the banisters, and had time for building. I'd donate a paddle wheel to the project. (Just 7 prims, and it can turn!)
I saw a very clever way to get around the standing-on-a-moving-vehicle problem. Someone built a nice looking pirate ship (over in InWorldz last Halloween) and had it stand still, while a REGION SIZED prop rotated past it. The illusion was great, you stood on the deck and watched the scenery scroll past. They could have dances on a "moving" boat!
