Ever seen a fish with forward rudder?
Philip C Bolger was the first to expiriment with the concept *(at least in
modern history).

One his more interesting experiments/essays... actually he tried it
twice, first time on a boat with a sharpie hull and an experimental
double-luff full-batten main. This boat was very difficult to sail and
was an unmitigated failure (one of the best things about Bolger is he
tells what he's tried that *doesn't* work); but he thought the forward
rudder had possibilities and tried it on another boat of well tried
design.
