While this video is not the one that caught my eye, it does demonstrate the principle involved. He's got a sensible, inexpensive, strong, floatable and roomy answer to getting across the ice safely.

(The drive "blade" was smaller and much more robust in the earlier video).
Factoid:
Early French missionaries crossed frozen North American lakes using fully loaded canoes. Some relied on sail power!
