This may sound crazy, but I am almost 99.9% sure that my wife and I saw this going south on I-95 in the area you are speaking of. I only say this because of the grass stencils that are painted on the hull and the back.... We were heading home from Fort Lauderdale to Jax, and when I saw this boat, we got into a conversation about all of the Airboats in brevard county. There was a truck directly behind it, pulling another one that was black hull, with blue tubing( whatever the frame is called that the seats and stuff are on).
I don't think that really helps, but I figured it was better than not saying anything.
