I've known about the Bottsand for ages - it's basically a floating German pooper-scooper for oil slicks - and I still can't work out if it's an act of genius or an office joke that went too far.
Anyway, once it's bored of mopping oil it folds back up to become a more conventional looking ship again.
People are mentioning RP FLIP, so just in case anyone wants to know what that's all about here's an image...
It's apparently considered pretty poor form to press the "rotate" button when the captain is using the heads.
@diamondhell I mean, the British are still trying to make Ajax a thing. That's going to end up as a running military joke.
The Zubr hovercraft is an obvious candidate for your criteria though?
@DreadShips the 60s is when pretty much anything that can take top trumps in some way was built.
Whatever it was, it likely drank like Oliver Reed and was uncomfortable as hell, but went like a stabbed rat.
See Concorde, hovercrafts of all types, hydrofoils and many other things for further details
@diamondhell 1950s banged pretty hard as well, to be fair. I suspect some of the dafter modern stuff is classified or will only look silly in retrospect - it's possibly just too early to judge.
Airlander's flying bum was mooted for military use?

I didn't know you did airships as well!
"And what's yours?"
