Why not try a YuhlooYuhloo




An uleau is an oar with about a 15 degree bend in the handle
perdendicular to the plane of the oar and a pivot at that point,
which presents the oar blade sideways, perpendicular to the desired
direction of travel. The end of the handle is tied by a piece of
rope several feet long to the interior of the boat. Moving the oar
handle sideways by pulling and pushing on the rope causes the blade,
along with the bend and pivot, to work in the water like the blade
of a propellor, equally to either side, "sculling" the oar. Each
reversal of the handle causes the blade to pivot a few degrees, so
the blade pushes or pulls the boat with each side to side motion.
Manipulation of the handle permits steering. The blade is lifted
from the water to enable coasting between strokes, if desirable.
Pushing or pulling harder to one side or the other also enables
steering.

A rubber flipper stuck on a typical rudder may also serve, with
technique.
