Are you talking about the “quadski”? Link doesn’t work but I’ve seen the quadski. Google it for a you tube link.
My thoughts…for atv use, the hull would get damaged without question be it from from rock chips, logs, etc. To easy to get high centered, not very nimble.
As a jet ski…better keep it in a straight line, I could see turning sharp and the wheels catching water and throwing the rider.
As a unit, to much “electronics” with the power up/down wheels. Surely the electric motors make more weight, more parts to wear out. How strong are the axles/pivot points when it’s a “atv”.
Kind of a neat idea but who’s gonna buy something like that? It’s not as useful as a atv and can’t be as fast or nimble as a jet ski. Maybe for the guy that has everything and money to burn??
I wasn’t impressed.
