Having had both a car trailer and a boat trailer, I think aguyindallas is correct. They will both have the same wheel width... around 8.5 feet. That means the boat wheels would fall off the edge of the car trailer.
Some states allow one trailer to pull another (triples). Shocking to me, and scary to tow. But, I'm in MN, and it's allowed here. I've seen a truck pulling a travel trailer, with a boat behind the trailer. Not sure if you could legally do this from OH to TX, but maybe. Check the rules and limits before trying this! And, don't back up!
Otherwise, sell the car trailer and get another one in TX. For the few hundred you may sacrifice, it may be easier than the hassle.
