Haha it sounds a little cheesy right? But then again, I really miss better affordable VR equiment myself. Not really for shock and vibration but rather orientation and visuals.

On the sub, there was a rather successful project of a hydroglider / low altitude plane though. Kind of similar. It was a ship that would fly at 2 meters altitude or so when speed up. It could carry a huge load of material however and was gigantic. I would have to get my books out to find the correct name though and it'd be too off topic anyways =p

Madfish, You're probably thinking of ground effect vehicles - like the Soviet Ekranoplan:
