How about the "drive" on the "sailboat" which instead of the sail has a
slowly rotating verticle tube. Any wind from any direction can be
converted to forward propulsion, even straight into the wind if I
remember correctly.
I have a picture of an old ferryboat with 4 horses in a turnstile,
which turns a paddlewheel. It was sort of Rube Goldberg, as there
wasn't room for much else.

Looks like it would rock for slow speed manuevering, but I bet you could get
some interesting side slip if you jack it around at speed.
