Here is the company I have used a few times... They are a broker and can handle it all for you. They don't put it in a container. They trailer it into the belly of a boat and it goes with all the new cars that are being exported to China and Australia. Probably best for you to deliver the boat to port. The boat needs to be winterized, tower folded, guide poles off, and shrinkwrapped.
