Too small? That's kinda funny. Do you need to transport all the way to the ocean or could there be a much closer body of water that can be navigated to the ocean? A flatbed truck or trailer would work from Ryder or U-Haul, perhaps.
Where is the boat?
Another thought is to buy a trailer of the right size, if you can't find a Capri 22 trailer, and have a welding or trailer repair shop modify it to fit. Then you have a trailer too.
