Okay something that has bugged me for a long time is how Zartan's Chameleon Swamp Skier works. So from the look of the vehicle it basically operates like a hydrofoil. The main body houses a small jet engine that pushes the craft through the water and up onto the front and back skis and it zips along the surface of the water. We've seen it in action like this in the cartoon.

What bothers me though is that there doesn't appear to be any structure or mechanism that allows it to float when its not moving. In the cartoon when they were stopped and tied up to the dock (as I recall) they floated on the skis as though the skis were pontoons, which clearly they aren't unless they are made of some magical lighter than air material.

Also the underside of the body is just the outer housing of the jet engine and doesn't appear to have any kind of hull wrapped around it. Is the body frame also made of the same magical hover metal as the skis?

I know that G.I. Joe is full of strange and unbelievable concepts and that a lot of it shouldn't work in the real world. But this vehicle, one of my favorites as a kid, just defies the laws of physics in extraordinarily blatant ways. I could totally see this functioning as a land vehicle, skating along snow like a fancy jet powered snowmobile. But in the water when it isn't moving this thing should sink like a rock.
Any thoughts?
