Dear Bryan,

        Whales swim using their tail flukes for propulsion.  The up-and-down
motion of the broad flukes goes as an up-stroke and down (power) stroke.
They steer an brake using their pectroal flippers.  Beacuase they are
streamlined (fusiform) they can get a lot of mileage for a little energy
however, most whales don't move very fast for very long.  The smaller whales
(dolphins and porpoises) can reach speeds of 29 miles per hour or so but
can't run that way for a very long time.

Ask me some more if this doesn't answer your question.
