I recently watched an on-ice demonstration video of a 14-foot craft that has features to put pricy ice-craft to shame.
It was a 12-or 14-foot aluminum rowboat (or jonboat). It was powered by small pull-srart engine driving a "blade".
The "blade" (diameter about 12- to 14-inches) was lowered outboard-style onto the ice, where it dug into the ice surface and the boat took off!
Of course, the aluminum bottom must have been battered, but the video didn't show any anticipated protections.
There are older previous threads on the subject. I'll try to find others.
