Photo 1 for 1973 Caraboat, "mirage"

Hello, I have been interested in a Caraboat for years. I am from Germany and my name is Marc. I would like to know what the rust situation is like, especially on the supporting parts. The axle that is built into the hull. That is a weak point of the Caraboat. Can you tell me what it looks like under the wooden floor or at best send me a photo. I would be very happy to get more information. Is the Caraboat registered and can it be driven on the road? Kind regards Marc
