It's interesting that there are five different styles of the same idea shown in this thread. This last one is definitely unique though- visible drive sprocket and cogs(?) on each end of the pontoon, although it is a roller track.
Is that a screw drive unit in the middle?
a single steering ski up front?
You can still see where the pontoon rotated enough to hit the box.
Curious that the lights were removed in the B&W photos . . .
