Yeah, I'm the one who brought this game up first because I ran across a copy of it on eBay which I snagged right away. (I was the only bidder, too, and it was 5 bucks...Heh.)
I haven't gone back to playing it again since my first time trying it but it does look cool... the framerate is not the greatest (think Daytona USA) but the gfx look pleasant and the water and spray effects are done nicely enough. It's competitive boat racing in big basins and it's not very easy, I tell you that. I still have to figure out the whole control thing, actually. The game also features loads and loads and loads of menus, statistical data (of real-life Japanese boat-racing teams I think) and options, it's difficult to get through it all, or maybe just at first.
I'd be happy to go back to the game and make some screenshots as best I can with my webcam... Just let me know...
