To insure full employment and reduce fuel consumption for barges we need to bring back oar-powered galleys. A trireme will look great on our rivers and with its three banks of rowers will be capable of getting over thirty miles against a two knot current per pizza per man.
That would also provide jobs for drummers! Ya gotta have someone mark the rowing rhythm.
We shall convert the US Navy into a progressive galleon powered peace force. The rowing will be carried out by white males only. No talking! PULL!!!!!
