Waverace 64 as jet boats

Wasn't this game originally going to be about futuristic jet boats or something like that? Are there any shots of that?

Is this the kind of thing that you mean?

 

Yup that's it. I think I remember seeing shots of that in magazines at some point. F-Zero on water is what comes to mind.

Thanks for the link.
