Put a set ( 4 of them ) on the Bayou Skiff so it can be rowed while facing backwards or forwards in the center seat. Forwards only from the back seat.
You might have a problem with the pirogue since it is narrower then the skiff but a set of short oars might do it. The Uncle John pirogue is 31 at the beam and the Bayou Skiff is 43 for a 12 inch difference.
