When one needs to transport a large powerboat great distances, it presents a rather wasteful problem. See, you have plenty of livable space on the boat, but said boat is up on a trailer, thus one must either tow one's craft with a large RV or stay in hotels. The owner of this... thing evidently thought that was too wasteful in the name of epic leisure. As such, you see the incredible contraption in front of you.
There are any of a number of places you'd expect to find a Ferrari: at the race track, on the auction block, in the showroom, parked in front of the swankiest restaurants in town... To see one in the water usually spells trouble, but history is not without its exceptions.
